Memory disclosure via out-of-bounds VOB parsing
Published Sep 8, 2021 · Updated Sep 16, 2024
An out-of-bounds read in Adobe Media Encoder 15.1 and earlier allows remote attackers to disclose process memory through a crafted VOB file. The VOB parser reads beyond an allocated buffer while processing attacker-controlled file data, exposing adjacent memory in the current user's process. Exploitation requires a user to open the malicious file on Windows; the reported consequence is limited to memory disclosure.

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=unspecified <=15.1
- Affected versionversion=unspecified <=None
