CVE-2020-0801Network attack vector

Code execution via crafted Media Foundation content

Published Mar 12, 2020 · Updated Aug 4, 2024

Memory corruption in Windows Media Foundation in Microsoft Windows allows remote attackers to execute code through crafted media content. The framework improperly handles media objects in memory, causing an out-of-bounds write when it processes crafted content. Exploitation requires a user to open a crafted document or visit a malicious webpage, after which code runs with that user's privileges.
