| CVE-2026-110836 | 1 Freerdp | 1 Freerdp | 2026-10-20 | 6.5 Medium |
| FreeRDP from 3.0.0 before 3.32.0 contains an infinite loop vulnerability in http_response_recv() that allows malicious gateways to exhaust client CPU via crafted Content-Type headers. Attackers controlling a gateway can return a nonzero Content-Length with a semicolon-containing unrecognized Content-Type, pinning a client thread at full CPU indefinitely. | ||||
| CVE-2026-110831 | 1 Freerdp | 1 Freerdp | 2026-10-20 | 4.3 Medium |
| FreeRDP versions 3.13.0 before 3.32.0 contain a resource retention flaw in drive_process_irp_create, which registers an opened local file in the drive dictionary before applying the allocation size and does not remove it when that operation fails. A malicious RDP server connected to a client with drive redirection enabled can send IRP_MJ_CREATE with AllocationSize set to UINT64_MAX, forcing the seek to fail and leaking the file object and operating-system handle until drive teardown. | ||||
| CVE-2026-111881 | 1 Freerdp | 1 Freerdp | 2026-10-19 | 7.6 High |
| FreeRDP from 3.14.1 before 3.32.0 contains an integer underflow in the WinPR BMP writer, where a mismatched stride calculation passes SIZE_MAX - 3 to Stream_Zero for sub-byte images. A malicious RDP clipboard peer can return a crafted 1-bpp BMP processed by clipboard_synthesize_image_format_to_bmp for CF_DIB/CF_DIBV5, crashing the client or causing an out-of-bounds write. | ||||
| CVE-2026-111880 | 1 Freerdp | 1 Freerdp | 2026-10-19 | 7.4 High |
| FreeRDP versions from 2.0.0 before 3.32.0 contain a heap out-of-bounds write in the server hash-callback NTLM path that fails to validate the MIC offset. Unauthenticated attackers can send a crafted AUTHENTICATE_MESSAGE with a backward session-key offset and MIC offset to write 16 zero bytes beyond the allocation. | ||||
| CVE-2026-110835 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 4 Medium |
| FreeRDP 3.0.0 before 3.32.0 allows HTTP header injection in its proxy because a lone LF in the target portion of a routing token (Cookie: msts=) is not rejected and is written by http_proxy_connect into the CONNECT request line and Host header. A remote unauthenticated RDP client connecting to a proxy using FixedTarget=false and an upstream HTTP proxy can alter HTTP request/header framing at that upstream proxy. | ||||
| CVE-2026-109951 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 5.3 Medium |
| FreeRDP 3.17.1 before 3.32.0 contains a heap buffer over-read vulnerability in DynvcTrackerHandleCreateBack of the freerdp-proxy DRDYNVC channel handler that allows malicious backend RDP servers to read heap memory out of bounds. Attackers can send a CREATE_REQUEST_PDU whose channel name lacks a NUL byte, causing an unbounded snprintf read that leaks memory into proxy logs or crashes the process. | ||||
| CVE-2026-109946 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 6.5 Medium |
| FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by sending an in-bounds region rectangle with an odd width. | ||||
| CVE-2026-109941 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 6.5 Medium |
| FreeRDP from 2.3.0 before 3.32.0 contains an infinite loop vulnerability in http_chuncked_read that allows malicious RD Gateways to hang clients by sending incomplete chunked responses. Attackers can send a partial chunk-size line or footer followed by a clean TLS shutdown, causing zero-byte reads to loop forever and freeze the client decoder thread. | ||||
| CVE-2026-109256 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 5.3 Medium |
| FreeRDP 3.10.0 through 3.32.2 contains a heap buffer overflow in the WinPR png_write_data callback that writes past the buffer after a realloc failure. A malicious RDP clipboard peer can supply a large CF_DIB image that triggers out-of-bounds memcpy during PNG conversion, causing a client crash. | ||||
| CVE-2026-109251 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 5.3 Medium |
| FreeRDP before 3.32.0 stores the server-supplied signed MS-RDPEGT geometry origin unchecked in an unsigned video surface coordinate, so the blit clamp in gdiVideoShowSurface() wraps in 32-bit arithmetic and is skipped. A malicious RDP server can send a negative topLevelLeft to clients connecting with /video, causing an out-of-bounds write of decoded H.264 picture data or a client abort. | ||||
| CVE-2026-109246 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 6.5 Medium |
| FreeRDP before 3.32.0 contains a divide-by-zero vulnerability in the freerdp-shadow-cli shadow server: the frame id in a client's Frame Acknowledge PDU is stored without a range check, so the in-flight frame count in shadow_encoder_inflight_frames() can underflow. An authenticated client can acknowledge a frame id one greater than the last frame sent, causing shadow_encoder_create_frame_id() to divide by zero (SIGFPE) and terminate the process, disconnecting all viewers. | ||||
| CVE-2026-109241 | 1 Freerdp | 1 Freerdp | 2026-10-18 | 3.1 Low |
| FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the client video redirection channel that allows malicious servers to crash clients by sending out-of-order messages. Attackers can send a Geometry CLEAR message that nulls presentation->geometry, then send VideoData that dereferences it, causing client denial of service. | ||||
| CVE-2026-109952 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 5.3 Medium |
| The FreeRDP client 3.0.0 before 3.32.0 does not check a server-selected PROTOCOL_RDSTLS or PROTOCOL_HYBRID_EX against its enabled protocol set in nego_process_negotiation_response(), allowing a security protocol downgrade. A malicious server or man-in-the-middle can select RDSTLS to override /sec:nla pinning, complete authentication with an all-zero cookie, and receive the user's cleartext password in the Client Info PDU. | ||||
| CVE-2026-111374 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 5.3 Medium |
| FreeRDP from 3.30.0 before 3.32.0 contains a resource exhaustion vulnerability in the rdpecam client that lets malicious RDP servers request unadvertised camera media types. Attackers can send a StartStreamsRequest with oversized dimensions to force large pending-sample allocations and reconfigure the local camera through the HAL. | ||||
| CVE-2026-111382 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 8.8 High |
| FreeRDP before 3.32.0 contains a client-side heap out-of-bounds write vulnerability in general_LumaToYUV444 and general_ChromaV2ToYUV444 that allows malicious RDP servers to corrupt client memory. Attackers can send RDPGFX AVC444 or AVC444v2 frames with odd-height region rects ending at surface height to write past U/V planes, enabling heap corruption and potential code execution. | ||||
| CVE-2026-111377 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 6.5 Medium |
| FreeRDP from 2.0.0 before 3.32.0 contains an unbounded reassembly vulnerability in WTSProcessChannelData that fails to enforce cumulative fragment limits. Authenticated clients can start a static virtual channel message, withhold the LAST flag, and send endless fragments to exhaust server memory. | ||||
| CVE-2026-110838 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 7.5 High |
| FreeRDP shadow server from 3.0.0 before 3.32.0 dispatches input PDUs during the Confirm Active state before authentication, allowing unauthenticated attackers to inject keyboard input. Attackers can negotiate TLS-only RDP and send an input PDU without Confirm Active to inject synthetic keystrokes into the host user's X11 session via XTEST. | ||||
| CVE-2026-110833 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 5.9 Medium |
| FreeRDP from 3.0.0-beta1 before 3.32.0 fails to enforce cumulative or absolute size limits when reassembling RDPDR channel fragments in the proxy. Attackers can send a FIRST fragment followed by continuation fragments without LAST, growing per-session heap streams proportional to traffic and exhausting proxy memory. | ||||
| CVE-2026-111378 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 7.5 High |
| FreeRDP from 3.0.0 before 3.32.0 contains an uncontrolled resource consumption vulnerability in parse_nla_mode_pdu that allows unauthenticated attackers to exhaust server memory. Attackers can complete TLS and stream bytes not beginning with the DER SEQUENCE tag 0x30, causing unbounded receive buffer growth before NLA authentication. | ||||
| CVE-2026-111373 | 1 Freerdp | 1 Freerdp | 2026-10-16 | 5.3 Medium |
| FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the websocket transport that allows a malicious gateway to crash clients by sending zero-length pings. When the payload length is zero, websocket_reply_pong passes a nullptr stream to websocket_reply_close, triggering an assertion failure that terminates the client process and causes denial of service. | ||||
