Sensitive-memory disclosure via unchecked JPEG2000 object use
Published Jan 14, 2022 · Updated Apr 23, 2025
Use-after-free in Adobe Bridge 11.1.2 and earlier and 12.0 and earlier allows remote attackers to read memory via a malicious JPEG2000 file. The JPEG2000 parser operates on an object without first validating its existence, causing access after the object's lifetime ends. A victim must visit a malicious page or open a malicious file; disclosure can expose process memory and help bypass ASLR, while code execution requires chaining with another 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.
- Affected versionversion=unspecified <=11.1.2
- Affected versionversion=unspecified <=12.0
- Affected versionversion=unspecified <=None
