FFmpeg: FFmpeg: Memory corruption via crafted RASC video stream

A flaw was found in FFmpeg's RASC video decoder. 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 vulnerability triggers a bitstream-controlled out-of-bounds heap write and an adjacent...

The vulnerability of the decode_dlta() function in the libavcodec/rasc.c file of the RASC video decoder from the FFmpeg multimedia library allows a attacker to cause a service failure.

The vulnerability of the decodedlta function in the libavcodec/rasc.c file of the RASC video decoder from the FFmpeg multimedia library is related to writing beyond the buffer boundaries. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the decodedlta function. An attacker can cause memory corruption, potentially leading to information disclosure, data modification, or application crash by supplying a crafted media stream containing a malicious...

CVE-2026-58049

FFmpeg's RASC video decoder decodedlta in libavcodec/rasc.c performs 32-bit reads and writes at the row cursor before the NEXTLINE 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...
