Important: freerdp security update
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox.
Security Fix(es):
-
freerdp: FreeRDP: Remote code execution via heap-buffer-overflow in gdi_CacheToSurface (CVE-2026-40033)
-
freerdp: FreeRDP: Arbitrary code execution or denial of service via heap use-after-free in RDPEAR NDR parser (CVE-2026-44422)
-
freerdp: FreeRDP: Out-of-bounds write in planar bitmap decoder allows arbitrary code execution (CVE-2026-45700)
-
freerdp: FreeRDP: Arbitrary code execution via crafted RDPGFX PDUs (CVE-2026-44421)
-
freerdp: FreeRDP: Arbitrary code execution and denial of service via heap-buffer-overflow (CVE-2026-44420)

FreeRDP before 3.26.0 contains a heap-buffer-overflow vulnerability in gdi_CacheToSurface that allows remote attackers to write out-of-bounds heap memory. The vulnerability occurs because rectangle validation clamps coordinates to UINT16_MAX but performs copy operations using unclamped cache entry dimensions, enabling malicious RDP servers to trigger large out-of-bounds writes and potentially achieve remote code execution or client crash.
