Ping @richsalz ?

richsalz · 2021-03-08T14:26:40Z

Seems reasonable. Is it necessary since openssl version outputs +quic in the vendor space?

jasnell · 2021-03-08T14:34:49Z

Is it necessary since openssl version outputs +quic in the vendor space?

Strictly speaking, we could use any mechanism that would be available at configure/make time. A #define is, by far, the easiest and least complicated of the options.

richsalz · 2021-03-08T14:40:04Z

A #define is, by far, the easiest and least complicated of the options.

Makes sense. And since openssl does it for all others, that makes sense. I think updating "disableables" variable in Configure should do it.

tmshort · 2021-03-08T14:44:35Z

quic is already in the Configure disableables list. It creates the the OPENSSL_NO_QUIC #define as needed, but there's no way to tell if it's enabled; as OpenSSL does things with inverse logic.

richsalz · 2021-03-08T15:21:32Z

Todd's right, of course. @jasnell if you to contort things. Rather than say "is quic enabled" you have to do "is quic not disabled." Ugh, but history:

#ifndef OPENSSL_NO_QUIC
    /* happy day, we can support quic with openssl */
#endif

#ifdef OPENSSL_NO_QUIC
   /* life has no meaning this openssl version cannot support quic */
#endif

tmshort · 2021-03-08T15:31:29Z

Yeah, the problem comes from trying to use vanilla openssl/openssl that does not have any concept of QUIC and the lack of OPENSSL_NO_QUIC does not mean that QUIC is available.

#ifndef OPENSL_NO_QUIC
    /* wait, do I have QUIC, or am I using vanilla OpenSSL that doesn't have any concept of QUIC? */
#endif

#ifdef OPENSSL_NO_QUIC
    /* Why-oh-why are we using a version of quictls/openssl without QUIC enabled?!?! */
#endif

#ifdef OPENSSL_INFO_QUIC
    /* Oh YES! */
#endif

This happens usually if an template object is created and there is an out of memory error before the ASN1_OP_NEW_POST method is called, but asn1_item_embed_free calls now the ASN1_OP_FREE_POST which may crash because the object is not properly initialized. Apparently that is only an issue with the ASN1_OP_FREE_POST handling of crypot/x509/x_crl.c, which ought to be tolerant to incomplete initialized objects. The error can be reproduced with the reproducible error injection patch: $ ERROR_INJECT=1652890550 ../util/shlib_wrap.sh ./asn1-test ./corpora/asn1/0ff17293911f54d1538b9896563a4048d67d9ee4 #0 0x7faae9dbeeba in __sanitizer_print_stack_trace ../../../../gcc-trunk/libsanitizer/asan/asan_stack.cpp:87 #1 0x408dc4 in my_malloc fuzz/test-corpus.c:114 #2 0x7faae99f2430 in CRYPTO_zalloc crypto/mem.c:230 #3 0x7faae97f09e5 in ASN1_STRING_type_new crypto/asn1/asn1_lib.c:341 #4 0x7faae98118f7 in asn1_primitive_new crypto/asn1/tasn_new.c:318 #5 0x7faae9812401 in asn1_item_embed_new crypto/asn1/tasn_new.c:78 #6 0x7faae9812401 in asn1_template_new crypto/asn1/tasn_new.c:240 #7 0x7faae9812315 in asn1_item_embed_new crypto/asn1/tasn_new.c:137 #8 0x7faae9812315 in asn1_template_new crypto/asn1/tasn_new.c:240 #9 0x7faae9812a54 in asn1_item_embed_new crypto/asn1/tasn_new.c:137 #10 0x7faae9812a54 in ASN1_item_ex_new crypto/asn1/tasn_new.c:39 #11 0x7faae980be51 in asn1_item_embed_d2i crypto/asn1/tasn_dec.c:325 #12 0x7faae980c813 in asn1_template_noexp_d2i crypto/asn1/tasn_dec.c:611 #13 0x7faae980d288 in asn1_template_ex_d2i crypto/asn1/tasn_dec.c:518 #14 0x7faae980b9ce in asn1_item_embed_d2i crypto/asn1/tasn_dec.c:382 #15 0x7faae980caf5 in asn1_template_noexp_d2i crypto/asn1/tasn_dec.c:643 #16 0x7faae980d7d3 in asn1_template_ex_d2i crypto/asn1/tasn_dec.c:494 #17 0x7faae980b9ce in asn1_item_embed_d2i crypto/asn1/tasn_dec.c:382 #18 0x7faae980dd1f in ASN1_item_ex_d2i crypto/asn1/tasn_dec.c:124 #19 0x7faae980de35 in ASN1_item_d2i crypto/asn1/tasn_dec.c:114 #20 0x40712c in FuzzerTestOneInput fuzz/asn1.c:301 #21 0x40893b in testfile fuzz/test-corpus.c:182 #22 0x406b86 in main fuzz/test-corpus.c:226 #23 0x7faae8eb1f44 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x21f44) AddressSanitizer:DEADLYSIGNAL ================================================================= ==1194==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000010 (pc 0x7faae9b0625f bp 0x7fffffe41a00 sp 0x7fffffe41920 T0) ==1194==The signal is caused by a READ memory access. ==1194==Hint: address points to the zero page. #0 0x7faae9b0625f in crl_cb crypto/x509/x_crl.c:258 #1 0x7faae9811255 in asn1_item_embed_free crypto/asn1/tasn_fre.c:113 #2 0x7faae9812a65 in asn1_item_embed_new crypto/asn1/tasn_new.c:150 #3 0x7faae9812a65 in ASN1_item_ex_new crypto/asn1/tasn_new.c:39 #4 0x7faae980be51 in asn1_item_embed_d2i crypto/asn1/tasn_dec.c:325 #5 0x7faae980c813 in asn1_template_noexp_d2i crypto/asn1/tasn_dec.c:611 #6 0x7faae980d288 in asn1_template_ex_d2i crypto/asn1/tasn_dec.c:518 #7 0x7faae980b9ce in asn1_item_embed_d2i crypto/asn1/tasn_dec.c:382 #8 0x7faae980caf5 in asn1_template_noexp_d2i crypto/asn1/tasn_dec.c:643 #9 0x7faae980d7d3 in asn1_template_ex_d2i crypto/asn1/tasn_dec.c:494 #10 0x7faae980b9ce in asn1_item_embed_d2i crypto/asn1/tasn_dec.c:382 #11 0x7faae980dd1f in ASN1_item_ex_d2i crypto/asn1/tasn_dec.c:124 #12 0x7faae980de35 in ASN1_item_d2i crypto/asn1/tasn_dec.c:114 #13 0x40712c in FuzzerTestOneInput fuzz/asn1.c:301 #14 0x40893b in testfile fuzz/test-corpus.c:182 #15 0x406b86 in main fuzz/test-corpus.c:226 #16 0x7faae8eb1f44 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x21f44) AddressSanitizer can not provide additional info.

This happens usually if an template object is created and there is an out of memory error before the ASN1_OP_NEW_POST method is called, but asn1_item_embed_free calls now the ASN1_OP_FREE_POST which may crash because the object is not properly initialized. Apparently that is only an issue with the ASN1_OP_FREE_POST handling of crypot/x509/x_crl.c, which ought to be tolerant to incomplete initialized objects.

Prior to the crash there is an out of memory error in X509_verify_cert which makes the chain NULL or empty. The error is ignored by ssl_add_cert_chain, and ssl_security_cert_chain crashes due to the unchecked null pointer. This is reproducible with my error injection patch. The test vector has been validated on the 1.1.1 branch but the issue is of course identical in all branches. $ ERROR_INJECT=1652848273 ../util/shlib_wrap.sh ./server-test ./corpora/server/47c8e933c4ec66fa3c309422283dfe0f31aafae8# ./corpora/server/47c8e933c4ec66fa3c309422283dfe0f31aafae8 #0 0x7f3a8f766eba in __sanitizer_print_stack_trace ../../../../gcc-trunk/libsanitizer/asan/asan_stack.cpp:87 #1 0x403ba4 in my_malloc fuzz/test-corpus.c:114 #2 0x7f3a8f39a430 in CRYPTO_zalloc crypto/mem.c:230 #3 0x7f3a8f46bd3b in sk_reserve crypto/stack/stack.c:180 #4 0x7f3a8f46bd3b in OPENSSL_sk_insert crypto/stack/stack.c:242 #5 0x7f3a8f4a4fd8 in sk_X509_push include/openssl/x509.h:99 #6 0x7f3a8f4a4fd8 in X509_verify_cert crypto/x509/x509_vfy.c:286 #7 0x7f3a8fed726e in ssl_add_cert_chain ssl/statem/statem_lib.c:959 #8 0x7f3a8fed726e in ssl3_output_cert_chain ssl/statem/statem_lib.c:1015 #9 0x7f3a8fee1c50 in tls_construct_server_certificate ssl/statem/statem_srvr.c:3812 #10 0x7f3a8feb8b0a in write_state_machine ssl/statem/statem.c:843 #11 0x7f3a8feb8b0a in state_machine ssl/statem/statem.c:443 #12 0x7f3a8fe84b3f in SSL_do_handshake ssl/ssl_lib.c:3718 #13 0x403202 in FuzzerTestOneInput fuzz/server.c:740 #14 0x40371b in testfile fuzz/test-corpus.c:182 #15 0x402856 in main fuzz/test-corpus.c:226 #16 0x7f3a8e859f44 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x21f44) #17 0x402936 (/home/ed/OPC/openssl/fuzz/server-test+0x402936) AddressSanitizer:DEADLYSIGNAL ================================================================= ==8400==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000158 (pc 0x7f3a8f4d822f bp 0x7ffc39b76190 sp 0x7ffc39b760a0 T0) ==8400==The signal is caused by a READ memory access. ==8400==Hint: address points to the zero page. #0 0x7f3a8f4d822f in x509v3_cache_extensions crypto/x509v3/v3_purp.c:386 #1 0x7f3a8f4d9d3a in X509_check_purpose crypto/x509v3/v3_purp.c:84 #2 0x7f3a8f4da02a in X509_get_extension_flags crypto/x509v3/v3_purp.c:921 #3 0x7f3a8feff7d2 in ssl_security_cert_sig ssl/t1_lib.c:2518 #4 0x7f3a8feff7d2 in ssl_security_cert ssl/t1_lib.c:2542 #5 0x7f3a8feffa03 in ssl_security_cert_chain ssl/t1_lib.c:2562 #6 0x7f3a8fed728d in ssl_add_cert_chain ssl/statem/statem_lib.c:963 #7 0x7f3a8fed728d in ssl3_output_cert_chain ssl/statem/statem_lib.c:1015 #8 0x7f3a8fee1c50 in tls_construct_server_certificate ssl/statem/statem_srvr.c:3812 #9 0x7f3a8feb8b0a in write_state_machine ssl/statem/statem.c:843 #10 0x7f3a8feb8b0a in state_machine ssl/statem/statem.c:443 #11 0x7f3a8fe84b3f in SSL_do_handshake ssl/ssl_lib.c:3718 #12 0x403202 in FuzzerTestOneInput fuzz/server.c:740 #13 0x40371b in testfile fuzz/test-corpus.c:182 #14 0x402856 in main fuzz/test-corpus.c:226 #15 0x7f3a8e859f44 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x21f44) #16 0x402936 (/home/ed/OPC/openssl/fuzz/server-test+0x402936) AddressSanitizer can not provide additional info.

This was found by my Reproducible Error Injection patch (openssl#18356) Due to the exact location of the injected memory error the sha256 digest is missing, and this causes much later the memory leak (and a failed assertion) in tls13_generate_secret. But the reproduction is a bit challenging, as it requires AESNI and RDRAND capability.

…STRINGS) A recursive OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS) call may happen if an out-of-memory error happens at the first callstack, and the dead-lock happens at the second callstack, because ossl_err_get_state_int calls OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS) although that call is currently already executing. At least on posix system this causes the process to freeze at this point, and must be avoided whatever it takes. The fix is using err_shelve_state around the critical region, which makes ossl_err_get_state_int return early and not call the recursive OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS). This can be reproduced with my error injection patch.

Sometimes the error handling returns an ASN1_STRING object in *out although that was not passed in by the caller, and sometimes the error handling deletes the ASN1_STRING but forgets to clear the *out parameter.

This may cause a use-after-free error e.g. in asn1_str2type: ==63312==ERROR: AddressSanitizer: heap-use-after-free on address 0x603000073280 at pc 0x7f2652e93b08 bp 0x7ffe0e1951c0 sp 0x7ffe0e1951b0 READ of size 8 at 0x603000073280 thread T0 #0 0x7f2652e93b07 in asn1_string_embed_free crypto/asn1/asn1_lib.c:354 #1 0x7f2652eb521a in asn1_primitive_free crypto/asn1/tasn_fre.c:204 #2 0x7f2652eb50a9 in asn1_primitive_free crypto/asn1/tasn_fre.c:199 #3 0x7f2652eb5b67 in ASN1_item_free crypto/asn1/tasn_fre.c:20 #4 0x7f2652e8e13b in asn1_str2type crypto/asn1/asn1_gen.c:740 #5 0x7f2652e8e13b in generate_v3 crypto/asn1/asn1_gen.c:137 #6 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #7 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #8 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #9 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #10 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #11 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #12 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #13 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #14 0x564ed19d5f25 in req_main apps/req.c:806 #15 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #16 0x564ed1985165 in main apps/openssl.c:183 #17 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 #18 0x564ed1985acd in _start (/home/ed/OPCToolboxV5/Source/Core/OpenSSL/openssl/apps/openssl+0x139acd) 0x603000073280 is located 16 bytes inside of 24-byte region [0x603000073270,0x603000073288) freed by thread T0 here: #0 0x7f265413440f in __interceptor_free ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:122 #1 0x7f265315a429 in CRYPTO_free crypto/mem.c:311 #2 0x7f265315a429 in CRYPTO_free crypto/mem.c:300 #3 0x7f2652e757b9 in ASN1_mbstring_ncopy crypto/asn1/a_mbstr.c:191 #4 0x7f2652e75ec5 in ASN1_mbstring_copy crypto/asn1/a_mbstr.c:38 #5 0x7f2652e8e227 in asn1_str2type crypto/asn1/asn1_gen.c:681 #6 0x7f2652e8e227 in generate_v3 crypto/asn1/asn1_gen.c:137 #7 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #8 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #9 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #10 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #11 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #12 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #13 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #14 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #15 0x564ed19d5f25 in req_main apps/req.c:806 #16 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #17 0x564ed1985165 in main apps/openssl.c:183 #18 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 previously allocated by thread T0 here: #0 0x7f2654134808 in __interceptor_malloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:144 #1 0x7f265315a4fd in CRYPTO_malloc crypto/mem.c:221 #2 0x7f265315a4fd in CRYPTO_malloc crypto/mem.c:198 #3 0x7f265315a945 in CRYPTO_zalloc crypto/mem.c:236 #4 0x7f2652e939a4 in ASN1_STRING_type_new crypto/asn1/asn1_lib.c:341 #5 0x7f2652e74e51 in ASN1_mbstring_ncopy crypto/asn1/a_mbstr.c:150 #6 0x7f2652e75ec5 in ASN1_mbstring_copy crypto/asn1/a_mbstr.c:38 #7 0x7f2652e8e227 in asn1_str2type crypto/asn1/asn1_gen.c:681 #8 0x7f2652e8e227 in generate_v3 crypto/asn1/asn1_gen.c:137 #9 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #10 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #11 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #12 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #13 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #14 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #15 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #16 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #17 0x564ed19d5f25 in req_main apps/req.c:806 #18 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #19 0x564ed1985165 in main apps/openssl.c:183 #20 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 Reviewed-by: Paul Yang <kaishen.yy@antfin.com> Reviewed-by: Tomas Mraz <tomas@openssl.org> (Merged from openssl#23138) (cherry picked from commit 73ebaac)

Sometimes the error handling returns an ASN1_STRING object in *out although that was not passed in by the caller, and sometimes the error handling deletes the ASN1_STRING but forgets to clear the *out parameter. Therefore the caller has no chance to know, if the leaked object in *out shall be deleted or not. This may cause a use-after-free error e.g. in asn1_str2type: ==63312==ERROR: AddressSanitizer: heap-use-after-free on address 0x603000073280 at pc 0x7f2652e93b08 bp 0x7ffe0e1951c0 sp 0x7ffe0e1951b0 READ of size 8 at 0x603000073280 thread T0 #0 0x7f2652e93b07 in asn1_string_embed_free crypto/asn1/asn1_lib.c:354 #1 0x7f2652eb521a in asn1_primitive_free crypto/asn1/tasn_fre.c:204 #2 0x7f2652eb50a9 in asn1_primitive_free crypto/asn1/tasn_fre.c:199 #3 0x7f2652eb5b67 in ASN1_item_free crypto/asn1/tasn_fre.c:20 #4 0x7f2652e8e13b in asn1_str2type crypto/asn1/asn1_gen.c:740 #5 0x7f2652e8e13b in generate_v3 crypto/asn1/asn1_gen.c:137 #6 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #7 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #8 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #9 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #10 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #11 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #12 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #13 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #14 0x564ed19d5f25 in req_main apps/req.c:806 #15 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #16 0x564ed1985165 in main apps/openssl.c:183 #17 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 #18 0x564ed1985acd in _start (/home/ed/OPCToolboxV5/Source/Core/OpenSSL/openssl/apps/openssl+0x139acd) 0x603000073280 is located 16 bytes inside of 24-byte region [0x603000073270,0x603000073288) freed by thread T0 here: #0 0x7f265413440f in __interceptor_free ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:122 #1 0x7f265315a429 in CRYPTO_free crypto/mem.c:311 #2 0x7f265315a429 in CRYPTO_free crypto/mem.c:300 #3 0x7f2652e757b9 in ASN1_mbstring_ncopy crypto/asn1/a_mbstr.c:191 #4 0x7f2652e75ec5 in ASN1_mbstring_copy crypto/asn1/a_mbstr.c:38 #5 0x7f2652e8e227 in asn1_str2type crypto/asn1/asn1_gen.c:681 #6 0x7f2652e8e227 in generate_v3 crypto/asn1/asn1_gen.c:137 #7 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #8 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #9 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #10 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #11 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #12 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #13 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #14 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #15 0x564ed19d5f25 in req_main apps/req.c:806 #16 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #17 0x564ed1985165 in main apps/openssl.c:183 #18 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 previously allocated by thread T0 here: #0 0x7f2654134808 in __interceptor_malloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:144 #1 0x7f265315a4fd in CRYPTO_malloc crypto/mem.c:221 #2 0x7f265315a4fd in CRYPTO_malloc crypto/mem.c:198 #3 0x7f265315a945 in CRYPTO_zalloc crypto/mem.c:236 #4 0x7f2652e939a4 in ASN1_STRING_type_new crypto/asn1/asn1_lib.c:341 #5 0x7f2652e74e51 in ASN1_mbstring_ncopy crypto/asn1/a_mbstr.c:150 #6 0x7f2652e75ec5 in ASN1_mbstring_copy crypto/asn1/a_mbstr.c:38 #7 0x7f2652e8e227 in asn1_str2type crypto/asn1/asn1_gen.c:681 #8 0x7f2652e8e227 in generate_v3 crypto/asn1/asn1_gen.c:137 #9 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #10 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #11 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #12 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #13 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #14 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #15 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #16 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #17 0x564ed19d5f25 in req_main apps/req.c:806 #18 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #19 0x564ed1985165 in main apps/openssl.c:183 #20 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 Reviewed-by: Tom Cosgrove <tom.cosgrove@arm.com> Reviewed-by: Tomas Mraz <tomas@openssl.org> (Merged from openssl#23165)

This may cause a use-after-free error e.g. in asn1_str2type: ==63312==ERROR: AddressSanitizer: heap-use-after-free on address 0x603000073280 at pc 0x7f2652e93b08 bp 0x7ffe0e1951c0 sp 0x7ffe0e1951b0 READ of size 8 at 0x603000073280 thread T0 #0 0x7f2652e93b07 in asn1_string_embed_free crypto/asn1/asn1_lib.c:354 #1 0x7f2652eb521a in asn1_primitive_free crypto/asn1/tasn_fre.c:204 #2 0x7f2652eb50a9 in asn1_primitive_free crypto/asn1/tasn_fre.c:199 #3 0x7f2652eb5b67 in ASN1_item_free crypto/asn1/tasn_fre.c:20 #4 0x7f2652e8e13b in asn1_str2type crypto/asn1/asn1_gen.c:740 #5 0x7f2652e8e13b in generate_v3 crypto/asn1/asn1_gen.c:137 #6 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #7 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #8 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #9 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #10 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #11 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #12 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #13 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #14 0x564ed19d5f25 in req_main apps/req.c:806 #15 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #16 0x564ed1985165 in main apps/openssl.c:183 #17 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 #18 0x564ed1985acd in _start (/home/ed/OPCToolboxV5/Source/Core/OpenSSL/openssl/apps/openssl+0x139acd) 0x603000073280 is located 16 bytes inside of 24-byte region [0x603000073270,0x603000073288) freed by thread T0 here: #0 0x7f265413440f in __interceptor_free ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:122 #1 0x7f265315a429 in CRYPTO_free crypto/mem.c:311 #2 0x7f265315a429 in CRYPTO_free crypto/mem.c:300 #3 0x7f2652e757b9 in ASN1_mbstring_ncopy crypto/asn1/a_mbstr.c:191 #4 0x7f2652e75ec5 in ASN1_mbstring_copy crypto/asn1/a_mbstr.c:38 #5 0x7f2652e8e227 in asn1_str2type crypto/asn1/asn1_gen.c:681 #6 0x7f2652e8e227 in generate_v3 crypto/asn1/asn1_gen.c:137 #7 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #8 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #9 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #10 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #11 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #12 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #13 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #14 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #15 0x564ed19d5f25 in req_main apps/req.c:806 #16 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #17 0x564ed1985165 in main apps/openssl.c:183 #18 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 previously allocated by thread T0 here: #0 0x7f2654134808 in __interceptor_malloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:144 #1 0x7f265315a4fd in CRYPTO_malloc crypto/mem.c:221 #2 0x7f265315a4fd in CRYPTO_malloc crypto/mem.c:198 #3 0x7f265315a945 in CRYPTO_zalloc crypto/mem.c:236 #4 0x7f2652e939a4 in ASN1_STRING_type_new crypto/asn1/asn1_lib.c:341 #5 0x7f2652e74e51 in ASN1_mbstring_ncopy crypto/asn1/a_mbstr.c:150 #6 0x7f2652e75ec5 in ASN1_mbstring_copy crypto/asn1/a_mbstr.c:38 #7 0x7f2652e8e227 in asn1_str2type crypto/asn1/asn1_gen.c:681 #8 0x7f2652e8e227 in generate_v3 crypto/asn1/asn1_gen.c:137 #9 0x7f2652e9166c in ASN1_generate_v3 crypto/asn1/asn1_gen.c:92 #10 0x7f2653307b9b in do_othername crypto/x509v3/v3_alt.c:577 #11 0x7f2653307b9b in a2i_GENERAL_NAME crypto/x509v3/v3_alt.c:492 #12 0x7f26533087c2 in v2i_subject_alt crypto/x509v3/v3_alt.c:327 #13 0x7f26533107fc in do_ext_nconf crypto/x509v3/v3_conf.c:100 #14 0x7f2653310f33 in X509V3_EXT_nconf crypto/x509v3/v3_conf.c:45 #15 0x7f2653311426 in X509V3_EXT_add_nconf_sk crypto/x509v3/v3_conf.c:312 #16 0x7f265331170c in X509V3_EXT_REQ_add_nconf crypto/x509v3/v3_conf.c:360 #17 0x564ed19d5f25 in req_main apps/req.c:806 #18 0x564ed19b8de0 in do_cmd apps/openssl.c:564 #19 0x564ed1985165 in main apps/openssl.c:183 #20 0x7f2651c4a082 in __libc_start_main ../csu/libc-start.c:308 Reviewed-by: Tom Cosgrove <tom.cosgrove@arm.com> Reviewed-by: Tomas Mraz <tomas@openssl.org> (Merged from openssl#23165) (cherry picked from commit dfa1e49)
