Remote code execution via crafted graphics document
Published May 11, 2021 · Updated Aug 3, 2024
Remote code execution in Microsoft Office Graphics allows attackers to execute code when a user opens a crafted document. Microsoft identifies the graphics component but has not disclosed the parser, file format, or incorrect operation performed on document content. Exploitation requires user interaction with a malicious file, after which attacker-controlled code runs in the affected Office process.
