Vendor Workaround
If the RASC decoder is not needed, it can be disabled at build time with --disable-decoder=rasc. There is no runtime workaround that disables the decoder without rebuilding FFmpeg.

| Description | A use-after-free vulnerability was found in FFmpeg's RASC video decoder. The decode_move() function initializes a read pointer into a decompressed buffer, but a subsequent reallocation of that same buffer during move-table processing leaves the pointer dangling. An attacker could exploit this by providing a specially crafted AVI file containing a malicious RASC video stream. When a user opens or plays the file, the decoder reads from freed heap memory, which could lead to a denial of service (crash). | |
