Sensitive memory disclosure via uninitialized MP4 access
Published Nov 16, 2023 · Updated Aug 2, 2024
Uninitialized pointer access in Adobe Media Encoder 24.0.2 and earlier and 23.6 and earlier allows attackers to disclose sensitive memory. During MP4 parsing, the application accesses memory through a pointer whose backing memory was not properly initialized. Exploitation requires a victim to open a crafted MP4 file; the resulting leak exposes process memory and can weaken ASLR for a separate exploit.

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.
- Affected versionversion=0 <=23.6
- Affected versionversion=0 <=24.0.2
