The original code didn't account for the fact that strchr() would match on the '\0' character, making it read past the end of the buffer if no non-whitespace character was present. This bug was introduced in commit ec5ff44 which was first released in systemd v221 and later fixed in commit 8595102 which was released in v240, so versions in the range [v221, v240) are affected.
The test cases from commit 8595102 check for the return value of syslog_parse_identifier() and will catch the condition that produced vulnerability from CVE-2018-16866. Add these tests to our stable branches. Tested that these tests will fail if the fix for CVE-2018-16866 is missing from the branch.

This wrapper is used in situations where we don't care about *San reports, we just want to make things work. However, with enabled LSan we might trigger some bogus reports we're definitely not interested in, causing unexpected test fails.
