CVE-2024-20739

Arbitrary code execution via unchecked AVI length

Published Feb 15, 2024 · Updated Aug 16, 2024

Heap-based buffer overflow in Adobe Audition 24.0.3, 23.6.2 and earlier allows remote attackers to execute code via a malicious AVI file. The AVI parser copies user-supplied data into a fixed-length heap buffer without validating its length. A victim must open the file or visit a malicious page, after which code runs with the current process privileges.
