Linux Distros Unpatched Vulnerability : CVE-2025-64720

high Nessus Plugin ID 276641

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.

 - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, an out-of-bounds read vulnerability exists in png_image_read_composite when processing palette images with PNG_FLAG_OPTIMIZE_ALPHA enabled. The palette compositing code in png_init_read_transformations incorrectly applies background compositing during premultiplication, violating the invariant component alpha 257 required by the simplified PNG API. This issue has been patched in version 1.6.51. (CVE-2025-64720)

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

Solution

There is no known solution at this time.
