EulerOS 2.0 SP12 : libpng (EulerOS-SA-2026-1072)

high Nessus Plugin ID 284729

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libpng package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

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, there is a heap buffer overflow vulnerability in the libpng simplified API function png_image_finish_read when processing 16-bit interlaced PNGs with 8-bit output format. Attacker-crafted interlaced PNG files cause heap writes beyond allocated buffer bounds. This issue has been patched in version 1.6.51.(CVE-2025-65018)

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)

Tenable has extracted the preceding description block directly from the EulerOS libpng security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libpng packages.
