Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Vulnerable OpenSSL is bundled in cryptography wheels for versions >=42.0.0, <44.0.1, and the fix is in cryptography 44.0.1. The source gives few details about the OpenSSL flaw or what an attacker needs to exploit it. Users installing prebuilt cryptography wheels from PyPI should upgrade to 44.0.1; those building from source must upgrade their own OpenSSL.
