CVE-2026-55193
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients using TS Gateway accept a server-controlled maxxmitfrag value in libfreerdp/core/gateway/rpcbind.c without bounding it to the 4088-byte ReceiveFragment allocation. A malicious gateway can advertise...
CVE-2026-55193 FreeRDP: Heap-buffer-overflow write in TS Gateway RPC fragment receive due to uncapped bind_ack max_xmit_frag
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, FreeRDP clients using TS Gateway accept a server-controlled maxxmitfrag value in libfreerdp/core/gateway/rpcbind.c without bounding it to the 4088-byte ReceiveFragment allocation. A malicious gateway can advertise...
CVE-2026-55193
FreeRDP clients using TS Gateway assign a server-controlled max_xmit_frag value (up to 65535) to rpc->max_recv_frag in rpc_bind.c without capping it to the 4088-byte ReceiveFragment buffer, so rpc_channel_read in rpc.c writes up to 65535 bytes, overflowing by up to 61447 attacker-controlled by...

CVE-2026-55564
CVE-2026-55564 is an out-of-bounds heap read in FreeRDP (a free RDP client implementation) affecting versions prior to 3.27.0 . The root cause is in glyph_cache_get() in libfreerdp/cache/glyph.c, which uses > instead of >= when bounds-checking the index against cache->number. A malicious...
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...
Amazon Linux 2023 : freerdp, freerdp-devel, freerdp-libs (ALAS2023-2026-2053)
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2053 advisory. FreeRDP before 3.28.0 affected outlength, so out-of-bounds bytes are written before the bounds check. On the server side, when a client selects RDP Standard Security, the encrypted client rand...
