Linux Distros Unpatched Vulnerability : CVE-2026-7774

medium Nessus Plugin ID 318726

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.

- tarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or directory-like names, to redirect later archive members outside the intended extraction directory. This allowed a malicious tar archive to cause tarfile.extractall() to write files outside the destination directory, subject to the permissions of the extracting process. (CVE-2026-7774)

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

Solution

There is no known solution at this time.
