Ubuntu 20.04 LTS / 22.04 LTS / 23.10 : GNU cpio vulnerabilities (USN-6755-1)

medium Nessus Plugin ID 194475

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6755-1 advisory.

 Ingo Brckl discovered that cpio contained a path traversal vulnerability. If a user or automated system were tricked into extracting a specially crafted cpio archive, an attacker could possibly use this issue to write arbitrary files outside the target directory on the host, even if using the option --no-absolute- filenames.

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

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

Solution

Update the affected cpio and / or cpio-win32 packages.
