CVE-2022-29105

Remote code execution via AVI parser buffer overwrite

Published May 10, 2022 · Updated Jan 2, 2025

Out-of-bounds write in Windows Media Foundation on affected Windows releases allows remote attackers to execute code through a crafted AVI file. The AVI parser fails to validate user-supplied data before writing past the end of an allocated buffer in the current process. Exploitation requires a user to open a malicious file or visit a malicious page, after which attacker-controlled code runs with that process's privileges.
