Important: freerdp

Issue Overview: FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, a NULL pointer dereference vulnerability in rdpwritelogoninfov2 allows a malicious RDP server to crash FreeRDP proxy by sending a specially crafted LogonInfoV2 PDU with cbDomain=0 or cbUserName=0. Th...

SUSE CVE-2026-27015

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a missing bounds check in smartcardunpackreadsizealign libfreerdp/utils/smartcardpack.c:1703 allows a malicious RDP server to crash the FreeRDP client via a reachable WINPRASSERT - abort. The crash occurs in...

SUSE CVE-2026-25941

FreeRDP is a free implementation of the Remote Desktop Protocol. Versions on the 2.x branch prior to to 2.11.8 and on the 3.x branch prior to 3.23.0 have an out-of-bounds read vulnerability in the FreeRDP client's RDPGFX channel that allows a malicious RDP server to read uninitialized heap memory...

SUSE CVE-2026-25954

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

CVE-2026-27950

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the fix for the heap-use-after-free described in CVE-2026-24680 is incomplete. While the vulnerable execution flow referenced in the advisory exists in the SDL2 implementation, the fix appears to have been...

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-2026-25955

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfAppUpdateWindowFromSurface reuses a cached XImage whose data pointer references a freed RDPGFX surface buffer, because gdiDeleteSurface frees surface-data without invalidating the appWindow-image that...

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...

UBUNTU-CVE-2026-26955

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a malicious RDP server can trigger a heap buffer overflow in FreeRDP clients using the GDI surface pipeline e.g., xfreerdp by sending an RDPGFX ClearCodec surface command with an out-of-bounds destination...

CVE-2026-25953

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfAppUpdateWindowFromSurface reads from a freed xfAppWindow because the RDPGFX DVC thread obtains a bare pointer via xfrailgetwindow without any lifetime protection, while the main thread can concurrently...

UBUNTU-CVE-2026-27015

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a missing bounds check in smartcardunpackreadsizealign libfreerdp/utils/smartcardpack.c:1703 allows a malicious RDP server to crash the FreeRDP client via a reachable WINPRASSERT → abort. The crash occurs in...
