CVE-2026-31884

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, division by zero in MS-ADPCM and IMA-ADPCM decoders when nBlockAlign is 0, leading to a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize where blocksize = context-common.format.nBlockAlign...

DEBIAN-CVE-2026-31883

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a sizet underflow in the IMA-ADPCM and MS-ADPCM audio decoders leads to heap-buffer-overflow write via the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM decoders subtract block header...

CVE-2026-29774

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a client-side heap buffer overflow occurs in the FreeRDP client's AVC420/AVC444 YUV-to-RGB conversion path due to missing horizontal bounds validation of H.264 metablock regionRects coordinates. In yuv.c, the clamp...

UBUNTU-CVE-2026-31885

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and stepindex values from input data. This vulnerability is fixed in 3.24.0...

CVE-2026-31806

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. The gdisurfacebits function, which processes SURFACEBITSCOMMAND messages, does not properly validate image dimensions bmp.width and bmp.height provided by a malicious RDP server. This can lead to a heap buffer...

CVE-2026-31897

FreeRDP vulnerability CVE-2026-31897: an out-of-bounds read in freerdp_bitmap_decompress_planar occurs when SrcSize is 0, dereferencing pSrcData without verifying SrcSize. This affects pre-3.24.0 releases and is fixed in 3.24.0. OpenSUSE/SUSE advisories and Amazon Linux 2 ALAS-2026-3239 also note...

CVE-2026-31897

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in freerdpbitmapdecompressplanar when SrcSize is 0. The function dereferences srcp which points to pSrcData without first verifying that SrcSize = 1. When SrcSize is 0 and pSrcData is...

CVE-2026-31806 FreeRDP has a Heap Buffer Overflow in nsc_process_message() via Unchecked SURFACE_BITS_COMMAND Bitmap Dimensions

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, the gdisurfacebits function processes SURFACEBITSCOMMAND messages sent by the RDP server. When the command is handled using NSCodec, the bmp.width and bmp.height values provided by the server are not properly...
