-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-a109a9ac2c 2026-06-02 01:10:43.197462+00:00 -------------------------------------------------------------------------------- Name : libpng Product : Fedora 43 Version : 1.6.58 Release : 1.fc43 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: updated to 1.6.58 1.6.58 is released with a fix for a simple correctness bug (not a security issue) this time: png_get_PLTE() returns stale palette data when either gamma correction or alpha-compositing is the only transform applied. Like the issues addressed in the previous release, this bug was a regression introduced in the fix for CVE-2026-33416 in 1.6.56. 1.6.57 is released with fixes for the following security vulnerability: CVE-2026-34757 (medium severity): Use-after-free memory bug in the chunk setter API. The hIST variant has existed since version 1.0.9, but the PLTE and tRNS ones are regressions introduced in the fix for CVE-2026-33416 in 1.6.56 (oops). -------------------------------------------------------------------------------- ChangeLog: * Thu May 21 2026 Michal Hlavinka <mhlavink@redhat.com> - 2:1.6.58-1 - updated to 1.6.58 (#2456815) -------------------------------------------------------------------------------- References: [ 1 ] Bug #2460625 - CVE-2026-22020 libpng: OpenJDK: Update LibPNG (Oracle CPU 2026-04) [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=2460625 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
