CVE-2020-3740

Code execution via malformed TIF file parsing

Published Feb 13, 2020 · Updated Aug 4, 2024

Memory corruption in Adobe FrameMaker 2019.0.4 and earlier allows remote attackers to execute code when a malicious TIF file is opened. The TIF parser fails to validate crafted file data before memory operations, corrupting process memory within the application. Exploitation requires a user to open the crafted file, and resulting code runs in the current user's context.
