- CVE-2025-64720 affecting package openjpeg2 2.3.1-12
- Details
-
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, an out-of-bounds read vulnerability exists in pngimagereadcomposite when processing palette images with PNGFLAGOPTIMIZEALPHA enabled. The palette compositing code in pnginitread_transformations incorrectly applies background compositing during premultiplication, violating the invariant component ≤ alpha × 257 required by the simplified PNG API. This issue has been patched in version 1.6.51.
