| CVE-2026-111380 | 1 Freerdp | 1 Freerdp | 2026-10-21 | N/A | 8.8 HIGH |
| FreeRDP from 3.29.0 before 3.32.0 contains an integer overflow in the Apple audin backends (audin_mac.m, audin_ios.m), which compute the audio queue buffer size as FramesPerPacket * 2 * nChannels in UINT32 arithmetic, bypassing the CVE-2026-91962 fix. A malicious RDP server can send FramesPerPacket of 2^30 in the audin Open PDU to wrap the multiplication, causing undersized AudioQueueAllocateBuffer allocations and a heap out-of-bounds write in macOS and iOS clients. | |||||
| CVE-2026-111375 | 1 Freerdp | 1 Freerdp | 2026-10-21 | N/A | 4.8 MEDIUM |
| FreeRDP from 3.0.0 before 3.32.0 contains an out-of-bounds read vulnerability in the Windows RAIL client that allows malicious RDP servers to trigger heap over-reads by sending non-NUL-terminated window titles. Attackers can send a full-length WINDOW_ORDER_FIELD_TITLE update that wf_rail_window_common passes to SetWindowTextW, corrupting titles or crashing the client. | |||||
| CVE-2026-109678 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 6.5 MEDIUM |
| FreeRDP 3.0.0-beta1 before 3.32.0, when built with verbose WinPR assertions and using smartcard emulation, has a reachable assertion: the emulated SCardStatusA passes a NULL reader-name destination to scard_copy_strings. A malicious RDP server can send an SCardStatusA request with fmszReaderNamesIsNULL=1 to abort a connecting client. | |||||
| CVE-2026-109679 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 5.3 MEDIUM |
| FreeRDP 3.0.0-beta4 before 3.32.0 contains a NULL pointer dereference in arm_handle_request_ok when an ARM endpoint returns an empty HTTP 200 body. Attackers controlling the configured ARM gateway can return a zero-length body to pass NULL to strnlen and crash the connecting client. | |||||
| CVE-2026-109680 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 5.3 MEDIUM |
| FreeRDP 3.18.0 before 3.32.0 has a heap-based out-of-bounds write in freerdp_interruptible_get_line, which shrinks the buffer to 32 bytes while keeping a pre-filled suggested username's length as its write offset. A malicious or compromised ARM routing service can return a long redirectedUsername that reaches the CLI credential prompt, crashing the client when the user types input. | |||||
| CVE-2026-111373 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 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. | |||||
| CVE-2026-111374 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 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-2026-111376 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 5.0 MEDIUM |
| FreeRDP from 3.30.0 before 3.32.0 contains a heap out-of-bounds read vulnerability in the Windows client's CliprdrStream_New that allows malicious RDP servers to trigger invalid memory reads via short clipboard responses. Attackers can answer a FILECONTENTS_SIZE request with a cbRequested of fewer than eight bytes when a user pastes a remote file, crashing the client or corrupting the stream size. | |||||
| CVE-2026-111377 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 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-2026-111378 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 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-2026-111381 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 7.3 HIGH |
| FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v2 that allows local attackers to corrupt heap memory via integer wraparound in bitmap size calculation. Attackers can craft a persistent cache v2 file with oversized width and height values that causes mismatched entry size accounting and fixed 16 KiB reads, leading to crashes or code execution when loaded. | |||||
| CVE-2026-111382 | 1 Freerdp | 1 Freerdp | 2026-10-20 | N/A | 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-2025-68118 | 1 Freerdp | 1 Freerdp | 2026-10-13 | N/A | 9.1 CRITICAL |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.0, a vulnerability exists in FreeRDP’s certificate handling code on Windows platforms. The function `freerdp_certificate_data_hash_ uses` the Microsoft-specific `_snprintf` function to format certificate cache filenames without guaranteeing NUL termination when truncation occurs. According to Microsoft documentation, `_snprintf` does not append a terminating NUL byte if the formatted output exceeds the destination buffer size. If an attacker controls the hostname value (for example via server redirection or a crafted .rdp file), the resulting filename buffer may not be NUL-terminated. Subsequent string operations performed on this buffer may read beyond the allocated memory region, resulting in a heap-based out-of-bounds read. In default configurations, the connection is typically terminated before sensitive data can be meaningfully exposed, but unintended memory read or a client crash may still occur under certain conditions. Version 3.20.0 has a patch for the issue. | |||||
| CVE-2026-67289 | 1 Freerdp | 1 Freerdp | 2026-10-02 | N/A | 9.8 CRITICAL |
| FreeRDP before 3.29.0 (affected versions <= 3.28.0) does not validate CRLF and control characters in the server-controlled RDP redirection TargetNetAddress field. This value is copied into the client's ServerHostname and, when the client connects through an HTTP proxy, is written directly into the proxy CONNECT request line and Host header by http_proxy_connect() without filtering. A malicious or compromised RDP server can send a crafted redirection PDU containing embedded control characters to inject arbitrary headers/requests into the HTTP proxy CONNECT request. | |||||
| CVE-2026-66402 | 1 Freerdp | 1 Freerdp | 2026-10-02 | N/A | 9.8 CRITICAL |
| FreeRDP before 3.29.0 (affected versions <= 3.28.0) contains multiple TLS certificate identity validation weaknesses in tls_verify_certificate(), tls_match_hostname(), and x509_utils_get_dns_names(). Because FreeRDP performs custom Common Name and DNS SAN string matching instead of using OpenSSL's length-aware identity validation APIs, it (1) truncates DNS SAN values at embedded NUL bytes (accepting e.g. 'victim.example\0.attacker.example' as 'victim.example'), (2) accepts a matching Common Name even when non-matching DNS SAN entries are present, and (3) accepts IP-literal targets via DNS/CN matching without comparing iPAddress SANs. Under a trusted or misissued certificate chain, an attacker positioned to present such a certificate can bypass server identity verification, weakening TLS server authentication. | |||||
| CVE-2026-67290 | 1 Freerdp | 1 Freerdp | 2026-09-29 | N/A | 7.5 HIGH |
| FreeRDP before 3.29.0 contains a heap out-of-bounds read vulnerability in the TSMF FFmpeg decoder when parsing AVC1 MPEG2VIDEOINFO media types with insufficient ExtraData. Attackers can send malformed media format data from a server to trigger a crash by reading fixed offsets without validating source buffer length. | |||||
| CVE-2026-67293 | 1 Freerdp | 1 Freerdp | 2026-09-29 | N/A | 4.2 MEDIUM |
| FreeRDP before 3.29.0 (affected versions <= 3.28.0) contains an improper certificate hostname validation vulnerability. The TLS hostname matcher (tls_match_hostname() in libfreerdp/crypto/tls.c) treats a wildcard pattern such as *.example.com as matching any hostname ending in .example.com, so it incorrectly accepts a wildcard certificate for multi-label subdomains like a.b.example.com (which OpenSSL's X509_check_host() rejects). This weakens TLS server authentication under wildcard-certificate conditions. | |||||
| CVE-2026-67303 | 1 Freerdp | 1 Freerdp | 2026-09-29 | N/A | 4.3 MEDIUM |
| FreeRDP before 3.29.0 contains a reachable assertion (WINPR_ASSERT(OutputBufferLength == BytesReturned)) in serial_process_irp_device_control() in channels/serial/client/serial_main.c. When serial device redirection is enabled and a server-controlled IRP_MJ_DEVICE_CONTROL request specifies an unsupported IOCTL with a non-zero OutputBufferLength, CommDeviceIoControl() can fail with BytesReturned = 0, causing the mismatch to trigger the assertion and abort the client process (denial of service). | |||||
| CVE-2026-68579 | 1 Freerdp | 1 Freerdp | 2026-09-29 | N/A | 9.6 CRITICAL |
| FreeRDP before 3.30.0 (<= 3.29.0) contains a heap-based buffer overflow in the Windows clipboard client's CliprdrStream_Read function (client/Windows/wf_cliprdr.c). When an OLE paste consumer (e.g. explorer.exe) calls IStream::Read with a fixed-size buffer of cb bytes, CliprdrStream_Read requests file contents from the RDP server and then copies the response into the caller's buffer using the server-supplied length (req_fsize) instead of cb. A malicious or compromised RDP server can return an oversized CB_FILECONTENTS_RESPONSE, causing an out-of-bounds write of attacker-controlled data into the paste consumer's heap buffer when a user pastes server-offered clipboard file contents. | |||||
| CVE-2026-68580 | 1 Freerdp | 1 Freerdp | 2026-09-29 | N/A | 7.5 HIGH |
| FreeRDP before 3.29.0 contains integer overflow vulnerabilities in the audio input redirection channel (audin) across ALSA, sndio, WinMM, and OpenSL ES backends that fail to validate the FramesPerPacket parameter from RDP servers. Attackers can supply a malicious FramesPerPacket value causing allocation size wraparound, resulting in heap-based buffer overflow on ALSA or denial of service on all platforms. | |||||
