NixOS vulnerability analysis and mitigation
Overview
GPAC mp4box version 1.1.0-DEV-rev1759-geb2d1e6dd contains a heap-buffer-overflow vulnerability in the function gfisomappleenumtag. This vulnerability was discovered in February 2022 and affects the MP4Box component of GPAC (NVD, MITRE).
Technical details
The vulnerability exists in the gfisomappleenumtag function located in src/isomedia/isom_read.c. When processing certain MP4 files, the function performs a read operation that exceeds the allocated buffer size, specifically reading 1 byte beyond a 5-byte allocated region at address 0x6020000014f5. This heap-buffer-overflow was detected by AddressSanitizer during testing (GitHub Issue).
Impact
A successful exploitation of this vulnerability could lead to memory corruption, potentially resulting in program crashes or arbitrary code execution. The vulnerability affects the MP4Box component, which is a key tool in GPAC for manipulating MP4 files.
Mitigation and workarounds
Users should upgrade to a version of GPAC that contains the fix for this vulnerability. If upgrading is not immediately possible, users should exercise caution when processing untrusted MP4 files with the MP4Box tool.
