Sensitive memory disclosure via TIF parser out-of-bounds read
Published Sep 29, 2021 · Updated Sep 17, 2024
Out-of-bounds read in Adobe FrameMaker versions through 2019 Update 8 and 2020 Update 2 allows attackers to disclose memory via malicious TIF files. The TIF parser reads beyond a valid buffer when processing crafted image data, exposing sensitive process memory that can help bypass ASLR. Exploitation requires a victim to open the malicious file, so impact is limited to memory disclosure and mitigation bypass rather than code execution or service interruption.

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 <=2019.8
- Affected versionversion=unspecified <=2020.2
- Affected versionversion=unspecified <=None
