Process abort via unchecked sgpd allocation
Published Aug 5, 2025 · Updated Aug 5, 2025
Uncontrolled resource consumption in Bento4 mp4decrypt 1.6.0-641 and earlier allows remote attackers to abort the process via a malformed MP4 file. An sgpd atom's unchecked 0xFFFFFFFC declared size reaches AP4_DataBuffer::SetDataSize and ReallocateBuffer, whose failed 4 GB allocation throws an uncaught std::bad_alloc. Exploitation requires mp4decrypt to parse an attacker-controlled file; the demonstrated consequence is immediate termination of that process, without reported data disclosure or modification.
