CVE-2021-36067

Code execution via out-of-bounds memory access

Published Sep 1, 2021 · Updated Apr 23, 2025

Memory corruption in Adobe Bridge 11.1 and earlier allows local users to execute arbitrary code by opening a malicious Bridge file. Adobe identifies an access-after-end-of-buffer error but has not disclosed the affected parser or the operation that crosses the buffer boundary. Exploitation requires the current user to open the crafted file, and resulting code runs with that user's privileges.
