Ubuntu 22.04 LTS / 24.04 LTS / 25.10 : libpng vulnerabilities (USN-8251-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8251-1 advisory. It was discovered that libpng incorrectly handled memory when processing certain PNG files. If a user or automated system were tricke...

USN-8251-1 libpng1.6 vulnerabilities

It was discovered that libpng incorrectly handled memory when processing certain PNG files. If a user or automated system were tricked into opening a specially crafted PNG file, an attacker could use this issue to cause libpng to crash, resulting in a denial of service, or possibly execute...

CVE-2026-33020 libsixel: Integer Overflow in write_png_to_file() leads to Heap-based Buffer Overflow

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. Versions 1.8.7 and prior contain an integer overflow which leads to a heap buffer overflow via sixelframeconverttorgb888 in frame.c, where allocation size and pointer offset computations for palettised images PAL1, PAL...
