Heap-based buffer overflow in Windows GDI+ allows an unauthorized attacker to execute code locally.
AnalysisAI
Local code execution in Windows GDI+ (the Graphics Device Interface Plus rendering component) affects a broad range of Microsoft Windows client and server releases from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through Server 2025. An attacker who convinces a user to open or preview a specially crafted image or document triggers a heap-based buffer overflow (CWE-122) during graphics parsing, yielding arbitrary code execution in the context of the current user. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:N/UI:R); there is no public exploit identified at time of analysis and it is not listed in CISA KEV, but GDI+ image-parsing flaws are historically attractive to attackers.
