CVE-2021-40792

User-assisted code execution via out-of-bounds buffer access

Published Mar 16, 2022 · Updated Apr 23, 2025

Memory corruption in Adobe Premiere Pro 15.4.1 and earlier allows context-dependent attackers to execute code through a malicious file. Adobe identifies an access after the end of a buffer during malicious-file handling but does not disclose the parser or code path. A user must open the file, after which code executes with the current user's privileges.
