high Nessus Plugin ID 251334

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - There is a defect in the CPython tarfile module affecting the TarFile extraction and entry enumeration APIs. The tar implementation would process tar archives with negative offsets without error, resulting in an infinite loop and deadlock during the parsing of maliciously crafted tar archives. This vulnerability can be mitigated by including the following patch after importing the tarfile module:
 https://gist.github.com/sethmlarson/1716ac5b82b73dbcbf23ad2eff8b33e1 (CVE-2025-8194)

Note that Nessus relies on the presence of the package as reported by the vendor.
