Check Point Research discovered three critical vulnerabilities in the Graphics Device Interface (GDI) of Windows, specifically affecting versions of GdiPlus.dll. The vulnerabilities, identified as CVE-2025-30388, CVE-2025-53766, and CVE-2025-47984, allow for potential remote code execution and unauthorized memory access, necessitating prompt patching by Microsoft during Patch Tuesday updates in May, July, and August 2025.
The flaws arise from improper handling of EMF+ metafiles leading to buffer overflows and memory corruption. For instance, CVE-2025-53766 was classified as critical due to its capability of being exploited without user interaction, making it particularly perilous for web applications. Another vulnerability, related to EMR_STARTDOC, highlights the ongoing challenge of ensuring complete security fixes as it reveals issues associated with earlier vulnerabilities that had received partial remediation.
The analysis accentuates the importance of rigorous security testing and collaboration between vendors and researchers to preempt future vulnerabilities. Ensuring comprehensive oversight in software patches is vital to protect user data and maintain system integrity against evolving cyber threats.
