High [CVE-2026-58049] Memory corruption via crafted RASC video stream
CVE-2026-58049Source published Source updated
FFmpeg's RASC video decoder (decode_dlta in libavcodec/rasc.c) performs 32-bit reads and writes at the row cursor before the NEXT_LINE row-boundary check and validates the DLTA region in pixel rather than byte units, so a DLTA run on a PAL8 frame can access several bytes past the row allocation. A crafted media stream using the RASC FourCC, decoded by libavcodec, triggers a bitstream-controlled out-of-bounds heap write and adjacent out-of-bounds read, leading to memory corruption. A remote attacker could exploit this by providing a crafted media stream using the RASC FourCC (Four Character Code), which is then decoded by libavcodec. This can result in a denial of service or potentially arbitrary code execution. Red Hat products utilizing FFmpeg for RASC video decoding are at risk if they…
