Summary
python2.7, python3.5, python3.6 vulnerabilities
Details

It was discovered that Python incorrectly handled certain plist files. If a user or an automated system were tricked into processing a specially crafted plist file, an attacker could possibly use this issue to consume resources, resulting in a denial of service. (CVE-2022-48564)

It was discovered that Python instances of ssl.SSLSocket were vulnerable to a bypass of the TLS handshake. An attacker could possibly use this issue to cause applications to treat unauthenticated received data before TLS handshake as authenticated data after TLS handshake. (CVE-2023-40217)
