An update for libpng is now available for openEuler-24.03-LTS,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP2,openEuler-24.03-LTS-SP3,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1205 Final 1.0 1.0 2026-01-23 Initial 2026-01-23 2026-01-23 openEuler SA Tool V1.0 2026-01-23 libpng security update An update for libpng is now available for openEuler-24.03-LTS,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP2,openEuler-24.03-LTS-SP3,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4 The libpng package contains libraries used by other programs for reading and writing PNG format files. The PNG format was designed as a replacement for GIF and, to a lesser extent, TIFF, with many improvements and extensions and lack of patent problems. Security Fix(es): 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.(CVE-2026-22695) LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From 1.6.26 to 1.6.53, there is an integer truncation in the libpng simplified write API functions png_write_image_16bit and png_write_image_8bit causes heap buffer over-read when the caller provides a negative row stride (for bottom-up image layouts) or a stride exceeding 65535 bytes. The bug was introduced in libpng 1.6.26 (October 2016) by casts added to silence compiler warnings on 16-bit systems. This vulnerability is fixed in 1.6.54.(CVE-2026-22801) An update for libpng is now available for openEuler-24.03-LTS,openEuler-24.03-LTS-SP1,openEuler-24.03-LTS-SP2,openEuler-24.03-LTS-SP3,openEuler-20.03-LTS-SP4,openEuler-22.03-LTS-SP4. openEuler Security has rated this update as having a security impact of medium.
