Linux Distros Unpatched Vulnerability : CVE-2026-55380

high Nessus Plugin ID 325336

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.

 - Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile._open() read image dimensions from the GD 2.x header and stored them in self._size without calling Image._decompression_bomb_check(), allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This issue is fixed in version 12.3.0. (CVE-2026-55380)

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

Solution

There is no known solution at this time.
