Memory disclosure via unchecked TIF buffer read
Published Dec 20, 2021 · Updated Apr 23, 2025
Out-of-bounds read in Adobe Dimension 3.4.3 and earlier allows remote attackers to disclose memory through a crafted TIF file. The TIF parser insufficiently validates user-supplied image data before reading past the end of an allocated buffer. Exploitation requires a victim to visit a malicious page or open the file; the resulting disclosure can weaken ASLR and support a separate exploit chain.

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 <=3.4.3
- Affected versionversion=unspecified <=None
