CVE-2026-25646

LIBPNG has a bug in the png_set_quantize() API prior to 1.6.55: when called with no histogram and the palette colors exceed twice the display’s maximum, certain palettes can cause an out-of-bounds read that may read past an internal heap buffer, potentially causing an infinite loop. The issue is ...

libtiff: LibTIFF Use-After-Free Vulnerability

A flaw was found in libtiff. The gethistogram function in file/tiffmedian.c exhibits a use-after-free condition when processing a specially crafted file, allowing a local attacker to trigger memory corruption. This manipulation results in a use-after-free vulnerability, and can lead to a denial o...
