The affected package points to the nonexistent pyssn1 project, while the upstream repository, release, and PyPI artifact all use pyasn1. Correct the package identifier so ecosystem matching reaches the affected project.

Problem
GHSA-m4p7-r5rc-7g4jidentifies the affected PyPI package aspyssn1. PyPI has no project by that name, while the advisory text, upstream repository, fix commit, and0.6.4security release all identifypyasn1. This mismatch prevents registry-based consumers from associating the advisory with the affected package.Change
