Hi, The following vulnerability was published for libpng1.6. CVE-2026-22801[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
