CVE-2024-39378

Arbitrary code execution via malformed AVI parsing

Published Sep 11, 2024 · Updated Sep 13, 2024

Out-of-bounds write in Adobe Audition 24.4.1 and earlier and 23.6.6 and earlier allows remote attackers to execute code via a malicious AVI file. Audition's AVI parser fails to validate user-supplied data before writing it, permitting a write beyond the end of an allocated buffer. Exploitation requires a victim to open the crafted file, and successful code execution runs in the context of the current user.
