Ubuntu update for python3.10

1) Input validation error

EUVDB-ID: #VU100516

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-11168

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass security restrictions.

The vulnerability exists due to insufficient validation of bracketed hosts (e.g. []) within the urllib.parse.urlsplit() and urlparse() functions allowing hosts that weren't IPv6 or IPvFuture. A remote attacker can pass specially crafted IP address to the application to bypass implemented IP-based security checks or perform SSRF attacks.

Mitigation

Update the affected package python3.10 to the latest version.
