EulerOS 2.0 SP11 : libpng (EulerOS-SA-2026-3132)

medium Nessus Plugin ID 333410

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the libpng packages 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 1.0.9 to before 1.6.57, passing a pointer obtained from png_get_PLTE, png_get_tRNS, or png_get_hIST back into the corresponding setter on the same png_struct/png_info pair causes the setter to read from freed memory and copy its contents into the replacement buffer. The setter frees the internal buffer before copying from the caller-supplied pointer, which now dangles. The freed region may contain stale data (producing silently corrupted chunk metadata) or data from subsequent heap allocations (leaking unrelated heap contents into the chunk struct). This vulnerability is fixed in 1.6.57.(CVE-2026-34757)

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

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

Solution

Update the affected libpng packages.
