CVE-2020-9654

Code execution via malformed MP4 parsing

Published Jun 25, 2020 · Updated Aug 4, 2024

Out-of-bounds write in Adobe Premiere Pro 14.2 and earlier allows remote attackers to execute arbitrary code through a crafted MP4 file. The MP4 parser fails to validate user-supplied data before writing past the end of an allocated structure. Exploitation requires the current user to visit a malicious page or open a malicious file, and resulting code runs in the Premiere Pro process.
