Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS : pip vulnerabilities (USN-8344-1)

high Nessus Plugin ID 318170

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8344-1 advisory.

 It was discovered that pip incorrectly handled TLS certificate verification in session connections. If a session was first used with certificate verification disabled, subsequent requests to the same host would also skip verification regardless of the session's current settings. A remote attacker could possibly use this issue to perform a machine-in-the-middle attack and expose sensitive information. (CVE-2024-35195)

 It was discovered that pip's bundled urllib3 library did not limit the number of decompression steps when processing HTTP responses. A remote attacker could possibly use this issue to cause pip to consume excessive resources, leading to a denial of service. (CVE-2025-66418)

 It was discovered that pip's bundled urllib3 library improperly handled streaming decompression of highly compressed data. A remote attacker could possibly use this issue to cause pip to consume excessive resources, leading to a denial of service. (CVE-2025-66471)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected python3-pip and / or python3-pip-whl packages.
