python3.5, python3.8 vulnerabilities
==========================================================================

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

- Ubuntu 20.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Python.

Software Description:
- python3.8: An interactive high-level object-oriented language
- python3.5: An interactive high-level object-oriented language

Details:

It was discovered that the Python ipaddress module contained incorrect
information about which IP address ranges were considered “private” or
“globally reachable”. This could possibly result in applications applying
incorrect security policies. This issue only affected Ubuntu 14.04 LTS
and Ubuntu 16.04 LTS. (CVE-2024-4032)

It was discovered that Python incorrectly handled quoting 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. (CVE-2024-9287)

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 Ubuntu 14.04 LTS
and Ubuntu 16.04 LTS. (CVE-2024-11168)

It was discovered that Python incorrectly handled parsing domain names that
included square brackets. A remote attacker could possibly use this issue
to perform a Server-Side Request Forgery (SSRF) attack. (CVE-2025-0938)
