Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS : Python vulnerabilities (USN-7886-1)

low Nessus Plugin ID 276714

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7886-1 advisory.

 It was discovered that Python inefficiently handled expanding system environment variables. An attacker could possibly use this issue to cause Python to consume excessive resources, leading to a denial of service. (CVE-2025-6075)

 Caleb Brown discovered that Python incorrectly handled the ZIP64 End of Central Directory (EOCD) Locator record offset value. An attacker could possibly use this issue to obfuscate malicious content.
 (CVE-2025-8291)

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 packages.
