- Details
-
FFmpeg through 8.1.2, fixed in commit aafb5c6, contains a signed integer overflow vulnerability in the MACE6 audio decoder that allows attackers to corrupt heap memory by supplying a crafted CAF file with a malicious bytesperpacket value. Attackers can craft a CAF file with oversized bytesperpacket and framesperpacket values in the desc chunk to trigger an integer overflow in macedecodeframe() during output sample count computation, resulting in an undersized buffer allocation and heap out-of-bounds write that could enable code execution.
