Linux Distros Unpatched Vulnerability : CVE-2026-76219

high Nessus Plugin ID 338197

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.

 - GitPython versions before 3.1.58 contain an arbitrary file overwrite vulnerability in IndexFile.from_tree, IndexFile.reset, and IndexFile.merge_tree methods that append caller-influenced treeish strings to git read-tree without option validation or argument separation. Attackers can inject the --index-output option to overwrite arbitrary files with a valid git-index blob, destroying existing file content at attacker- controlled writable paths. (CVE-2026-76219)

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

Solution

There is no known solution at this time.
