CVE-2026-44637 libsixel: integer overflow in parser

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, a signed integer overflow in the SIXEL parser's image-buffer doubling loop can lead to an out-of-bounds heap write in sixeldecoderawimpl. context-posx grows by repeatcount on every sixel character wit...

CVE-2026-44637

CVE-2026-44637 affects libsixel (SIXEL encoder/decoder). A signed integer overflow in the parser’s image-buffer doubling loop (sixel_decode_raw_impl) occurs as context->pos_x is incremented by repeat_count with no upper bound check. When pos_x nears INT_MAX, pos_x + repeat_count overflows sign...

CVE-2026-44636

CVE-2026-44636 affects libsixel (SIXEL encoder/decoder). A signed integer overflow in sixel_encode_highcolor’s allocation size calculation (widthheight) can cause a heap buffer overflow when encoding very large pixel buffers; callers may trigger allocation wrapping if width height > INT_MAX. T...
