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...

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...

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-2026-55191

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...

CVE-2026-75141

FFmpeg before commit acf5d7c contains a heap buffer overflow in the hvcC box writer. When writing an HEVC configuration record with more NAL units of a single type than the count field can represent, the NAL unit count overflows, causing a heap buffer overflow. A crafted HEVC input file triggers...
