CISA KEV Advisory
Microsoft Windows Graphics Device Interface (GDI) Remote Code Execution Vulnerability
A remote code execution vulnerability exists due to the way the Windows GDI component handles objects in the memory. An attacker who successfully exploits this vulnerability could take control of the affected system.
Apply updates per vendor instructions.
Risk Analysis
This remote code execution vulnerability in the Windows GDI component allows an attacker to take full control of an affected system by exploiting how it handles objects in memory. With an EPSS score of 0.40834 and inclusion in CISA's KEV, this vulnerability is actively exploited and represents a critical threat.
This vulnerability is actively exploited in the wild and is listed in CISA's KEV. It is remotely exploitable, likely through a crafted file or malicious content that interacts with the GDI component.
Apply all available security updates for Microsoft Windows to patch the GDI component. Ensure systems are regularly patched and consider implementing application whitelisting to prevent unauthorized code execution.
Technical Analysis
CVE-2016-3393 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2016-3393 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
