CVE-2023-47070

Code execution via unchecked MP4 object write

Published Nov 17, 2023 · Updated Aug 2, 2024

Out-of-bounds write in Adobe After Effects 24.0.2 and earlier and 23.6 and earlier allows remote attackers to execute code via a crafted MP4 file. The MP4 parser fails to validate user-supplied data before writing past the end of an allocated object. Exploitation requires a user to visit malicious content or open the file, and resulting code runs in the current process context.
