Description

python3.8, python3.10, python3.11 vulnerability USN-6513-1 fixed vulnerabilities in Python. This update provides the corresponding updates for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. Original advisory 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)
