USN-6513-2: Python vulnerability
27 November 2023
Several security issues were fixed in Python.
Releases
Packages
- python3.10 - An interactive high-level object-oriented language
- python3.11 - An interactive high-level object-oriented language
- python3.8 - An interactive high-level object-oriented language
Details
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 23.04
Ubuntu 22.04
Ubuntu 20.04
In general, a standard system update will make all the necessary changes.
