CVE-2026-55564 FreeRDP: Out-of-bounds read in glyph_cache_get via crafted glyph fragments

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-2026-55191 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

FreeRDP clients prior to 3.27.0 are vulnerable to a heap-buffer-overflow write in the RDPGFX AVC444 codec path. In libfreerdp/codec/h264.c, the function avc444_ensure_buffer() computes the intermediate YUV444 buffer size using 32-bit multiplication (piDstStride[x] * padDstHeight). A malicious RDP...
