CVE-2026-63633

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious Remote Desktop Protocol RDP server can exploit a heap buffer overflow vulnerability during Opus audio decoding. This occurs when the server negotiates Opus audio with a vulnerable client, causing the...

Rejected reason: REJECT DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2026-67306. Reason: This candidate is a duplicate of CVE-2026-67306. Notes: All CVE users should reference CVE-2026-67306 instead of this candidate...

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...

EUVD-2026-62673

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.29.0, planardecompressplanerle and planardecompressplanerleonly in libfreerdp/codec/planar.c verify that a control byte exists but do not verify that the source buffer contains the zero to fifteen raw bytes declared by th...

CVE-2026-69159 FreeRDP: Out-of-Bounds Read in Planar RLE Decoder (planar_decompress_plane_rle / planar_decompress_plane_rle_only)

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.29.0, planardecompressplanerle and planardecompressplanerleonly in libfreerdp/codec/planar.c verify that a control byte exists but do not verify that the source buffer contains the zero to fifteen raw bytes declared by th...

CVE-2026-63633 FreeRDP: Heap buffer overflow in Opus audio decode (`freerdp_dsp_decode_opus` resizes the wrong stream) — server→client

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 FreeRDP: Out-of-bounds read in H.264 YUV-to-RGB conversion due to decoder/surface dimension mismatch

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...
