CVE-2022-3784:
NixOS vulnerability analysis and mitigation
Overview
A critical heap-based buffer overflow vulnerability was discovered in Axiomatic Bento4 version 5e7bb34, specifically affecting the AP4_Mp4AudioDsiParser::ReadBits function in the Ap4Mp4AudioInfo.cpp file of the mp4hls component. The vulnerability was disclosed on October 24, 2022, and is tracked as CVE-2022-3784 (GitHub Issue).
Technical details
The vulnerability exists in the ReadBits function at line 66 of Ap4Mp4AudioInfo.cpp. When processing certain MP4 files, the function attempts to read beyond the allocated buffer boundaries, resulting in a heap-based buffer overflow. This occurs during the parsing of audio sample data in the mp4hls component. The issue appears to be an incomplete fix of a previous vulnerability (GitHub Issue).
Impact
The vulnerability can lead to heap buffer overflow conditions when processing specially crafted MP4 files. This could potentially result in program crashes (Denial of Service) or arbitrary code execution. The attack can be triggered remotely by processing maliciously crafted MP4 files (GitHub Issue).
