-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-c6c617fe35 2026-04-25 01:21:36.172156+00:00 -------------------------------------------------------------------------------- Name : libpng Product : Fedora 44 Version : 1.6.56 Release : 1.fc44 URL : http://www.libpng.org/pub/png/ Summary : A library of functions for manipulating PNG image format files Description : The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. PNG is a bit-mapped graphics format similar to the GIF format. PNG was created to replace the GIF format, since GIF uses a patented data compression algorithm. Libpng should be installed if you need to manipulate PNG format image files. -------------------------------------------------------------------------------- Update Information: 1.6.56 is release fixes for the following two security vulnerabilities: CVE-2026-33416 (high severity): Use-after-free memory bug in the transparency and palette-handling code.

CVE-2026-33636 (high severity): Out-of-bounds read and write vulnerability in the ARM Neon palette-expansion code. This one was found and fixed by Taegu Ha and has existed since 1.6.36. The images that trigger these bugs are valid.
