UBUNTU-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-2026-31897

An out of bounds read flaw has been discovered in FreeRDP. This Out-of-bounds read exists in the freerdpbitmapdecompressplanar function when SrcSize is 0. This flaw may allow an attcker to read of 1 byte from heap memory in some situation. The more common and expected impact is a crash when the...

CVE-2026-31885

An out of bounds read flaw has been discovered in FreeRDP. This out-of-bounds read exists in the MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and stepindex values from input data. An attacker may be able to leverage this weakness to leak global data. Mitigation Mitigation for this...

CVE-2026-31884

A division by zero flaw has been discovered in FreeRDP. This division by zero exists in the 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. The...

CVE-2026-29774

A heap based buffer overflow flaw has been discovered in FreeRDP. 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. A malicious server can trigger a...

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-2026-31806

Summary: CVE-2026-31806 affects FreeRDP prior to 3.24.0, where the gdi_surface_bits() handler (NSCodec path) can process SURFACE_BITS_COMMAND messages with unsafe bmp.width/bmp.height values, enabling a heap buffer overflow by crafting server data. The issue arises when width/height are not prope...
