### GitHub Vulnerability Alerts

####
[GHSA-h4gh-qq45-vh27](https://redirect.github.com/pyca/cryptography/security/advisories/GHSA-h4gh-qq45-vh27)

pyca/cryptography's wheels include a statically linked copy of OpenSSL.
The versions of OpenSSL included in cryptography 37.0.0-43.0.0 are
vulnerable to a security issue. More details about the vulnerability
itself can be found in
https://openssl-library.org/news/secadv/20240903.txt.

If you are building cryptography source ("sdist") then you are
responsible for upgrading your copy of OpenSSL. Only users installing
from wheels built by the cryptography project (i.e., those distributed
on PyPI) need to update their cryptography versions.
