CVE-2026-109946

FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by...

CVE-2026-109946

The FreeRDP client versions 3.11.0 before 3.32.0 are vulnerable to a reachable assertion (CWE-617) during YUV444 conversion. The software fails to validate that AVC444 and AVC444v2 region widths are even numbers. A malicious or compromised RDP server can trigger a client crash by sending an in-bo...

FreeRDP: FreeRDP: Information Disclosure via RDPGFX ResetGraphics PDU

A flaw was found in FreeRDP. This information disclosure vulnerability exists in the RDPGFX server's ResetGraphics Protocol Data Unit PDU serializer.

Astra Linux – Vulnerability in freerdp2

FreeRDP is a set of free and open-source remote desktop protocol libraries and clients. In affected versions, an integer overflow in the freerdpbitmapplanarcontext function leads to a heap-buffer overflow. This affects FreeRDP-based clients. FreeRDP-based server implementations and proxies are no...

CVE-2026-55191

A flaw was found in FreeRDP. FreeRDP clients that negotiate RDPGFX AVC444 with an H.264 decoder backend are vulnerable to a heap-buffer-overflow. A malicious Remote Desktop Protocol RDP server can supply crafted surface dimensions, causing an undersized buffer to be allocated. This can lead to a...

EUVD-2026-62668

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP H.264 decoder backends can return YUV planes sized from the bitstream without comparing the decoded width and height to the RDPGFX surface dimensions used to validate region rectangles. A malicious RDP serve...

CVE-2026-55192

In FreeRDP prior to 3.27.0, H.264 decoder backends return YUV planes sized from the bitstream without comparing decoded dimensions to the RDPGFX surface size. A malicious RDP server can supply a smaller AVC420/AVC444 frame, causing out-of-bounds reads in yuv420_context_decode/avc420_yuv_to_rgb pa...

EUVD-2026-62660

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients that negotiate RDPGFX AVC444 with an H.264 decoder backend calculate the intermediate YUV444 allocation size in libfreerdp/codec/h264.c with 32-bit multiplication in avc444ensurebuffer. A malicious R...

CVE-2026-55191

The FreeRDP RDP client is vulnerable to a heap-buffer-overflow write in the libfreerdp/codec/h264.c file. When negotiating RDPGFX AVC444 with an H.264 decoder backend, the avc444_ensure_buffer() function performs a 32-bit multiplication to calculate the intermediate YUV444 allocation size. A mali...
