CVE-2026-44637

A flaw was found in libsixel, a SIXEL encoder/decoder implementation. A remote attacker, by providing specially crafted SIXEL data, can trigger a signed integer overflow in the SIXEL parser's image-buffer doubling loop. This overflow can bypass size checks and lead to an out-of-bounds heap write...
