Linux Distros Unpatched Vulnerability : CVE-2025-29769

high Nessus Plugin ID 234209

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.

 - libvips is a demand-driven, horizontally threaded image processing library. The heifsave operation could incorrectly determine the presence of an alpha channel in an input when it was not possible to determine the colour interpretation, known internally within libvips as multiband. There aren't many ways to create a multiband input, but it is possible with a well-crafted TIFF image. If a multiband TIFF input image had 4 channels and HEIF-based output was requested, this led to libvips creating a 3 channel HEIF image without an alpha channel but then attempting to write 4 channels of data. This caused a heap buffer overflow, which could crash the process. This vulnerability is fixed in 8.16.1. (CVE-2025-29769)

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

Solution

There is no known solution at this time.
