USN-6513-1: Python vulnerabilities
23 November 2023
Several security issues were fixed in Python.
Releases
Packages
- python2.7 - An interactive high-level object-oriented language
- python3.5 - An interactive high-level object-oriented language
- python3.6 - An interactive high-level object-oriented language
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)
