Doc Text:
A flaw was found in libpng, a reference library for processing PNG (Portable Network Graphics) image files. A local attacker could exploit a heap buffer over-read vulnerability in the `png_image_finish_read` function by tricking a user into processing a specially crafted interlaced 16-bit PNG file with an 8-bit output format and non-minimal row stride. This could lead to a denial of service (DoS) and potentially information disclosure.

Description OSIDB Bzimport 2026-01-13 00:10:35 UTC
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From 1.6.51 to 1.6.53, there is a heap buffer over-read in the libpng simplified API function png_image_finish_read when processing interlaced 16-bit PNGs with 8-bit output format and non-minimal row stride. This is a regression introduced by the fix for CVE-2025-65018. This vulnerability is fixed in 1.6.54.
