CVE-2026-55191

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 FreeRDP: Heap-buffer-overflow write in AVC444 YUV buffer allocation

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-2026-55564: Out-of-bounds Read

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, the glyphcacheget function in libfreerdp/cache/glyph.c checks whether index is greater than cache-number instead of greater than or equal to it. A malicious RDP server can use GLYPHFRAGMENTUSE replay in...

CVE-2026-55193: Heap-based Buffer Overflow

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients using TS Gateway accept a server-controlled maxxmitfrag value in libfreerdp/core/gateway/rpcbind.c without bounding it to the 4088-byte ReceiveFragment allocation. A malicious gateway can advertise...

CVE-2026-55648: Integer Overflow or Wraparound

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdpimagecopyfromicondata in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixelformat in 32-bit arithmetic. A malicious RDP server can send a RAIL TSICONINFO...

CVE-2026-63633: Heap-based Buffer Overflow

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, freerdpdspdecodeopus in libfreerdp/codec/dsp.c calls StreamEnsureRemainingCapacity on context-common.buffer even though opusdecode writes decoded PCM into the caller-supplied out stream. A malicious RDP server that...

CVE-2026-55192: Out-of-bounds Read

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-2026-55194: Heap-based Buffer Overflow

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, rpcclientrecvfragment in libfreerdp/core/gateway/rpcclient.c ensures the response reassembly stream capacity using only the server-declared allochint rather than the actual StubLength about to be written. A maliciou...

SUSE CVE-2026-73241

FreeRDP is a free implementation of the Remote Desktop Protocol.
