freerdp: FreeRDP global-buffer-overflow

A global buffer overflow flaw has been discovered in FreeRDP. This global-buffer-overflow was observed in FreeRDP's Base64 decoding path. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char is treated as unsigned, so the guard c = 0 can be...

SUSE CVE-2026-25942

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfrailserverexecuteresult indexes the global errorcodenames array 7 elements, indices 0-6 with an unchecked execResult-execResult value received from the server, allowing an out-of-bounds read when the serve...

CVE-2026-25952

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfSetWindowMinMaxInfo dereferences a freed xfAppWindow pointer because xfrailgetwindow in xfrailserverminmaxinfo returns an unprotected pointer from the railWindows hash table, and the main thread can...

CVE-2026-26271

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread in freerdpimagecopyfromicondata libfreerdp/codec/color.c can be triggered by crafted RDP Window Icon TSICONINFO data. The bug is reachable over the network when a client processes icon data...

CVE-2026-25954

CVE-2026-25954 affects FreeRDP. The vulnerability arises in the RAIL path where xf_rail_get_window returns a pointer from the railWindows hash table that is freed by the main thread while the RAIL channel thread is still using it, allowing dereferencing of a freed xfAppWindow pointer. This race c...
