Memory disclosure via improper GDI object handling
Published May 21, 2020 · Updated Aug 19, 2026
Information disclosure in Windows GDI allows remote attackers to read process memory by inducing a user to open crafted content. The GDI object-handling path returns memory contents from improperly handled graphics objects; Microsoft has not published a more specific function or object type. Exploitation requires user interaction with a crafted document or untrusted webpage, and the disclosed data can aid further system compromise.
