Memory disclosure via uninitialized MP4 parser access
Published Nov 16, 2023 · Updated Jun 11, 2025
Uninitialized pointer access in Adobe Bridge 14.0.0 and earlier allows attackers to disclose process memory through a crafted MP4 file. The MP4 parser accesses memory through an uninitialized pointer instead of initializing it before use, exposing sensitive process contents. Exploitation requires a victim to open the malicious file, and the disclosed memory can help bypass ASLR or support a separate code-execution flaw.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
