CVE-2026-63652
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, rdpsndserverrecvformats in channels/rdpsnd/server/rdpsndmain.c frees context-clientformats on a malformed Client Audio Formats PDU without clearing the owning pointer or numclientformats. An authenticated RDP client...
UBUNTU-CVE-2026-63117
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, an authenticated RDP client can advertise DVI ADPCM with nBlockAlign equal to 8 and nChannels equal to 2 to make the bs calculation in rdpsndserverselectformat in channels/rdpsnd/server/rdpsndmain.c equal zero. The...

CVE-2026-69159
This CVE is a duplicate of CVE-2026-67306; users should reference that identifier instead. The underlying vulnerability is an out-of-bounds read in FreeRDP prior to 3.29.0 , specifically in planar_decompress_plane_rle and planar_decompress_plane_rle_only in libfreerdp/codec/planar.c. The function...
CVE-2026-63633
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 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 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-2026-55194 FreeRDPHeap-buffer-overflow write in TS Gateway RPC RESPONSE reassembly due to alloc_hint capacity mismatch
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, rpcclientrecvfragment in libfreerdp/core/gateway/rpcclient.c ensures the response reassembly stream capacity using only the server-declared allochint rather than the actual StubLength about to be written. A maliciou...
CVE-2026-55648 FreeRDP: Integer Overflow in `freerdp_image_copy_from_icon_data` Bypasses Bounds Check
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdpimagecopyfromicondata in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixelformat in 32-bit arithmetic. A malicious RDP server can send a RAIL TSICONINFO...

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-2026-55564 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-2026-55564
The FreeRDP RDP client is vulnerable to an out-of-bounds heap read in the glyph_cache_get function located in libfreerdp/cache/glyph.c. The root cause is an incorrect bounds check that uses the greater than (>) operator instead of the greater than or equal to (>=) operator. A malicious RDP ...
CVE-2026-74569
A flaw was found in the Linux kernel's netfilter Session Initiation Protocol SIP connection tracking module nfconntracksip. A remote attacker could send specially crafted SIP messages that cause an integer overflow during Network Address Translation NAT rewrite delta calculations. This overflow...
