Memory disclosure via uninitialized MP4 parser pointer
Published Aug 20, 2021 · Updated Sep 17, 2024
Access of an uninitialized pointer in Adobe Bridge 11.0.2 and earlier allows attackers to disclose process memory through a crafted MP4 file. The MP4 parser accesses a pointer before it is initialized, causing memory from the Bridge process to be returned during file parsing. Exploitation requires a victim to open the malicious file, and the documented consequence is memory disclosure in the current user's context.
