Name of the Vulnerable Software and Affected Versions
FreeRDP versions prior to 3.21.0
Description
A client-side heap buffer overflow exists in the FreeRDP client’s
gdi SurfaceToSurface path. This occurs due to a mismatch between destination rectangle clamping and the actual copy size. A malicious server can trigger this overflow, potentially leading to a crash (Denial of Service) and possible heap corruption, which could result in code execution depending on the allocator and heap layout. The vulnerable component is the gdi SurfaceToSurface function.Recommendations
Update to version 3.21.0 or later.
