CVE-2023-47046

Arbitrary code execution via out-of-bounds MP4 write

Published Nov 16, 2023 · Updated Feb 25, 2026

Out-of-bounds write in Adobe Audition 24.0 and earlier and 23.6.1 and earlier allows remote attackers to execute code via a crafted MP4 file. The MP4 parser fails to validate user-controlled data before a write exceeds an allocated buffer. Exploitation requires a user to open the malicious file, after which code runs with the privileges of the current process.
