Sensitive-memory disclosure via stale JPEG2000 object
Published Jan 13, 2022 · Updated Apr 23, 2025
Use-after-free in Adobe InCopy 16.4 and earlier allows context-dependent attackers to disclose sensitive memory via a crafted JPEG2000 file. The JPEG2000 parser performs operations on an object without validating that it still exists, leaving a stale reference that exposes process memory. A victim must open the malicious file, and the disclosure can weaken ASLR for a chained attack without directly altering data or interrupting the application.

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 <=16.4
