FreeRDP: FreeRDP: Denial of Service via crafted Surface Bits command

A flaw was found in FreeRDP. A malicious Remote Desktop Protocol RDP server can trigger a null pointer dereference in the gdisurfacebits function by sending a specially crafted Surface Bits command that claims to use the NSCodec codec ID. This vulnerability exists even when the NSCodec is disable...

freerdp: FreeRDP: Arbitrary code execution via crafted Remote Desktop Protocol (RDP) server messages

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. The gdisurfacebits function, which processes SURFACEBITSCOMMAND messages, does not properly validate image dimensions bmp.width and bmp.height provided by a malicious RDP server. This can lead to a heap buffer...

CVE-2026-31806

Summary: CVE-2026-31806 affects FreeRDP prior to 3.24.0, where the gdi_surface_bits() handler (NSCodec path) can process SURFACE_BITS_COMMAND messages with unsafe bmp.width/bmp.height values, enabling a heap buffer overflow by crafting server data. The issue arises when width/height are not prope...
