Vulnerability Title
FFmpeg MACE6 Audio Decoder Heap Out-of-Bounds Write via CAF File
Vulnerability Description
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 bytes_per_packet value. Attackers can craft a CAF file with oversized bytes_per_packet and frames_per_packet values in the desc chunk to trigger an integer overflow in mace_decode_frame() during output sample count computation, resulting in an undersized buffer allocation and heap out-of-bounds write that could enable code execution.

Vulnerability Title
FFmpeg 缓冲区错误漏洞
Vulnerability Description
FFmpeg是FFmpeg组织开源的一套可录制、转换以及流化音视频的完整解决方案。 FFmpeg 8.1.2及之前版本存在安全漏洞,该漏洞源于MACE6音频解码器中的有符号整数溢出,因为处理特制CAF文件时,desc chunk中的超大bytes_per_packet和frames_per_packet值在mace_decode_frame()中触发整数溢出,导致缓冲区分配不足和堆越界写入,可能允许攻击者执行代码。
