CVE-2026-49346

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in de265imagegetbuffer libde265/image.cc:128. The overflow wraps the plane allocation size to a sma...

CVE-2026-49346

CVE-2026-49346 affects libde265 up to version 1.0.x; a crafted H.265 bitstream with large SPS dimensions and 16-bit depth triggers a signed integer overflow in de265_image_get_buffer(), causing an undersized allocation (~1 KB) but later writing ~4 GB due to size_t math in fill_image. This is fixe...

CVE-2025-71330: Loop with Unreachable Exit Condition

image-size through 2.0.2 contains a denial of service vulnerability that allows remote attackers to permanently block the Node.js event loop by supplying a specially crafted ICNS image buffer. Attackers can craft an ICNS buffer containing valid magic bytes and a zero-valued entry length field to...

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...
