HighCVSS 8.4Exploitation Probability (EPSS)
Low risk21th percentile - higher than 21% of all known CVEs
Summary
A heap-based buffer overflow in Windows GDI+ allows an unauthorized attacker to execute code locally. The vulnerability occurs during the processing of specially crafted graphics data.
Risk Assessment
An attacker with local access to the system can exploit this vulnerability to escalate privileges and take control of the application or the entire operating system.
Recommendation
Immediately install the security update released by Microsoft for the GDI+ library. Restrict local system access to trusted users only.
