Ubuntu Security Notice USN-7488-1
May 06, 2025

python vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Python.

Software Description:
- python3.13: An interactive high-level object-oriented language
- python2.7: An interactive high-level object-oriented language
- python3.11: An interactive high-level object-oriented language
- python3.9: An interactive high-level object-oriented language
- python3.6: An interactive high-level object-oriented language
- python3.7: An interactive high-level object-oriented language
- python3.8: An interactive high-level object-oriented language
- python3.4: An interactive high-level object-oriented language

Details:

It was discovered that Python incorrectly handled parsing bracketed hosts.
A remote attacker could possibly use this issue to perform a Server-Side
Request Forgery (SSRF) attack. This issue only affected python 2.7 and
python3.4 on Ubuntu 14.04 LTS; python2.7 on Ubuntu 16.04 LTS;
python2.7, python3.6, python3.7, and python3.8 on Ubuntu 18.04 LTS;
python2.7 and python3.9 on Ubuntu 20.04 LTS; and python2.7 and
python3.11 on Ubuntu 22.04 LTS. (CVE-2024-11168)

It was discovered that Python allowed excessive backtracking while
parsing certain tarfile headers. A remote attacker could possibly use
this issue to cause Python to consume excessive resources, leading to
a denial of service. This issue only affected python3.4 on
Ubuntu 14.04 LTS; python3.6, python3.7, and python3.8 on
Ubuntu 18.04 LTS; python3.9 on Ubuntu 20.04 LTS; and python3.11 on
Ubuntu 22.04 LTS. (CVE-2024-6232)

It was discovered that Python incorrectly handled quoted path names
when using the venv module. A local attacker able to control virtual
environments could possibly use this issue to execute arbitrary code
when the virtual environment is activated. This issue only affected
python3.4 on Ubuntu 14.04 LTS; python3.6, python3.7, and python3.8
on Ubuntu 18.04 LTS; python3.9 on Ubuntu 20.04 LTS; python3.11 on
Ubuntu 22.04 LTS; and python3.13 on Ubuntu 24.10. (CVE-2024-9287)
