File-system information disclosure via uninitialized MP4 pointer
Published Aug 20, 2021 · Updated Apr 23, 2025
Improper input validation in Adobe Media Encoder 15.2 and earlier allows remote attackers to read file-system data through a crafted MP4 file. The MP4 parser accesses memory before proper initialization, exposing contents associated with the uninitialized pointer. A victim must open the malicious file, and the documented standalone impact is disclosure in the current user's context.
