Sensitive memory disclosure via TIF parsing
Published Jan 14, 2022 · Updated Apr 23, 2025
Out-of-bounds read in Adobe Illustrator 25.4.2 and earlier and 26.0.1 and earlier allows remote attackers to disclose memory via a malicious TIF. The TIF parser reads past the end of an allocated buffer when handling attacker-supplied file data, exposing sensitive process memory that can help bypass ASLR. Exploitation requires user interaction because a victim must open the crafted file; the documented impact is information disclosure rather than direct modification 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 <=25.4.2
- Affected versionversion=unspecified <=26.0.1
- Affected versionversion=unspecified <=None
