    3.32.1より前のFreeRDPには、WinPRのクリップボードPNGからCF_DIB合成にヒープベースの領域外読み取りが含まれています。これは、winpr_read_png_from_buffer()がビット深さが8未満のPNGにビットパックバッファを割り当てるのに対し、winpr_bitmap_write_buffer()がピクセルあたり1バイトであると想定して行をコピーするためです。悪意のある RDP サーバーが細工された低ビット深度の PNG クリップボード ペイロードを送信し、被害者が貼り付けると、ヒープ メモリのメガバイトが漏洩する可能性があります。(CVE-2026-114043)

    3.32.1前のFreeRDPでは、ブロックアライメントの算術をバイパスするrdpsnd_server_select_format()の整数ラップアラウンドが検証をバイパスするため、サーバーサイドのrdpsndチャンネルにヒープベースのバッファオーバーフロー DVI_ADPCM含まれています。悪意のあるRDPクライアントが、nChannelに対して小さすぎるnBlockAlignを持つ2つのSNDC_FORMATS PDUを送信し、サーバーオーディオの再生中に無制限のヒープ書き込みを引き起こし、コードの実行を引き起こす可能性があります。(CVE-2026-114045)

    3.32.0より前のFreeRDP3.0.0には、SCardGetStatusChangeリクエストでNULLのリーダーごとの名前を受け入れるスマートカードエミュレーションバックエンドにNULLポインターデリファレンスが含まれています。悪意のある RDP サーバーが細工された reader-state エントリを null szReader で送信し、strcmp または _wcscmp にクライアントプロセスをクラッシュさせる可能性があります。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - FreeRDP before 3.32.2 contains a NULL pointer dereference vulnerability that allows malicious RDP servers     to crash xfreerdp clients by sending a zero-width RDPGFX ResetGraphics PDU. The failed resize in     gdi_resize_ex leaves the primary display null without ending the session, so a later bitmap update crashes     the client in gdi_Bitmap_Paint. (CVE-2026-121402)

Note that Nessus relies on the presence of the package as reported by the vendor.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3342 advisory.

    FreeRDP before 3.32.1 contains a heap-based out-of-bounds read in WinPR's clipboard PNG-to-CF_DIB     synthesis because winpr_read_png_from_buffer() allocates a bit-packed buffer for PNGs with bit depth below     8, while winpr_bitmap_write_buffer() copies rows assuming one byte per pixel. A malicious RDP server can     send a crafted low-bit-depth PNG clipboard payload that, when pasted by the victim, discloses megabytes of     heap memory. (CVE-2026-114043)

    FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an     integer wraparound in rdpsnd_server_select_format() DVI_ADPCM block-alignment arithmetic bypasses     validation. A malicious RDP client can send two SNDC_FORMATS PDUs with an nBlockAlign too small for     nChannels, causing an unbounded heap write during server audio playback, potentially enabling code     execution. (CVE-2026-114045)

    FreeRDP 3.0.0 before 3.32.0 contains a null-pointer dereference in the smartcard emulation backend that     accepts a null per-reader name in SCardGetStatusChange requests. A malicious RDP server can send a crafted     reader-state entry with a null szReader, causing strcmp or _wcscmp to crash the client process.
    (CVE-2026-114046)

    FreeRDP from 2.0.0 before 3.32.0 contains an improper certificate validation vulnerability in its proxy     that accepts untrusted target TLS certificates when no verification module is configured. Network-     positioned attackers can intercept the proxy's outbound connection and present a self-signed, wrong-     hostname certificate to impersonate the RDP target and receive proxied session data. (CVE-2026-114047)

    FreeRDP before 3.32.2 contains a denial of service vulnerability in WinPR's winpr_read_png_from_buffer()     and winpr_convert_from_jpeg(), which lack libpng/libjpeg error handling. A malicious RDP server or MITM     can offer a malformed PNG or truncated JPEG clipboard payload, causing the client to abort or exit.
    (CVE-2026-121386)

    FreeRDP 2.0.0 before 3.32.2 contains an out-of-bounds read vulnerability in freerdp_dsp_decode_gsm610 that     allows malicious RDP servers to read past audio buffers by sending truncated GSM610 frames. Attackers can     negotiate GSM610 on rdpsnd and send a WAVE2 message shorter than a 33- or 32-byte WAV49 frame to crash the     client. (CVE-2026-121387)

    FreeRDP from 3.0.0 before 3.32.2 contains an uncontrolled resource allocation vulnerability that allows     malicious RDP servers to force large client allocations through the DRDYNVC DATA_FIRST Length field.
    Attackers can declare lengths up to 4,294,967,295 bytes on running dynamic channels, causing     StreamPool_Take to reserve memory before body validation and exhaust client memory. (CVE-2026-121388)

    FreeRDP from 3.27.0 before 3.32.2 contains a denial of service vulnerability in rdpdr_dump_packet that     allows malicious RDP servers to abort clients by sending malformed RDPDR device-list announcements.
    Attackers can declare a DeviceDataLength exceeding the received packet, triggering a fatal Stream_Seek     assertion when device redirection, TRACE logging, and WinPR assertions are enabled. (CVE-2026-121389)

    FreeRDP from 3.0.0 before 3.32.2 contains a file descriptor leak in parallel_process_irp_create that fails     to close previous descriptors on repeated IRP_MJ_CREATE requests. A hostile RDP server with parallel-     device redirection enabled can send repeated CREATE requests to exhaust the client descriptor table and     crash the process. (CVE-2026-121391)

    FreeRDP before 3.32.2 contains an improper certificate validation vulnerability in     tls_verify_certificate() that accepts Common Name fallback despite non-matching SAN entries and matches IP     literals against DNS strings. Man-in-the-middle attackers holding a certificate from a client-trusted CA     can bypass server identity checks to intercept RDP sessions, including keystrokes, clipboard, and screen     content. (CVE-2026-121392)

    FreeRDP from 3.0.0 before 3.32.2 contains a denial of service vulnerability that allows malicious RDP     servers to abort clients built with verbose WinPR assertions by sending crafted RemoteFX region     rectangles. Attackers can supply a rectangle with x set to 65535 alongside a SurfaceBits destination left     of 1, triggering a 16-bit coordinate assertion in rfx_process_message that terminates the client process.
    (CVE-2026-121393)

    FreeRDP clients from 3.0.0 before 3.32.2 built with verbose WinPR assertions contain a reachable assertion     in rts_read_auth_verifier triggered by malformed RTS padding. Attackers controlling an RD Gateway can send     a crafted RPC-over-HTTP RTS PDU with inconsistent authentication padding to abort the connecting client     process. (CVE-2026-121396)

    FreeRDP before 3.32.2 contains a heap buffer over-read vulnerability in save_png_to_buffer() that allows     malicious RDP servers to leak client memory by sending 16 bpp DIB clipboard data. Attackers can offer a     CF_DIB BI_BITFIELDS image that, when converted to PNG for a local application, embeds client heap bytes     into the clipboard image. (CVE-2026-121397)

    FreeRDP before 3.32.2 contains a cross-thread use-after-free vulnerability in the freerdp-proxy dyn-     channel-dump module during session teardown. A malicious RDP target can send dynamic channel data while     the front client disconnects, letting the client thread read freed ChannelData and crash the proxy     process. (CVE-2026-121398)

    FreeRDP before 3.32.2 contains a memory allocation vulnerability in rdg_receive_packet that allows a     malicious RD Gateway to force a 2 GiB client allocation before tunnel authentication. Attackers can send     an eight-byte RDG header declaring packet length 0x7FFFFFFF to trigger pre-authentication memory     exhaustion and denial of service. (CVE-2026-121399)

    FreeRDP before 3.32.2 contains a denial-of-service vulnerability in rdg_process_control_packet that allows     a malicious RD Gateway to exhaust client CPU by sending an incomplete keepalive control packet. Attackers     completing the RDG tunnel-open exchange then send an eight-byte header with packetLength 0xFFFF and     withhold the body, causing an unbounded no-progress read loop that spins one client thread at full CPU.
    (CVE-2026-121400)

    FreeRDP before 3.32.2 contains a denial of service vulnerability where rdg_process_packet dispatches a     PKT_TYPE_EXTENDED_AUTH_MSG without verifying negotiated mode or auth context. A malicious or compromised     RD Gateway can send the extended-auth packet before tunnel authentication, triggering a null-pointer     dereference that crashes the client. (CVE-2026-121401)

    FreeRDP before 3.32.2 contains a NULL pointer dereference vulnerability that allows malicious RDP servers     to crash xfreerdp clients by sending a zero-width RDPGFX ResetGraphics PDU. The failed resize in     gdi_resize_ex leaves the primary display null without ending the session, so a later bitmap update crashes     the client in gdi_Bitmap_Paint. (CVE-2026-121402)

    FreeRDP before 3.32.2 contains a denial of service vulnerability where a malformed drive DEVICE_IOREQUEST     with a truncated IRP_MJ_CREATE body silently kills the drive worker. A malicious RDP server can send such     an IRP then post further requests that accumulate unbounded in the IrpQueue, exhausting memory and causing     session availability loss. (CVE-2026-121403)

    FreeRDP before 3.32.2 contains a denial of service vulnerability in the shadow server that allows     authenticated RDP clients to spin server threads by sending zero-length drdynvc DATA PDUs. Attackers can     send empty DATA messages on opened audin or rdpgfx channels, so that FreeRDP_WTSVirtualChannelRead never     consumes them, consuming full CPU cores until disconnect. (CVE-2026-121404)

    FreeRDP before 3.32.2 fails to cap the OutputBufferLength in serial device-control IRP requests, allowing     malicious servers to trigger excessive memory allocation. Attackers running a server with serial     redirection can send an IRP_MJ_DEVICE_CONTROL request with IOCTL_USBPRINT_GET_1284_ID and a near-maximum     length to exhaust client memory. (CVE-2026-121405)

    FreeRDP before 3.32.2 allows a client assertion abort because rdpgfx_on_data_received rejects only     negative zgfx_decompress status and passes the resulting null output pointer to Stream_StaticConstInit. A     malicious RDP server can send a zero-output ZGFX payload on the RDPGFX channel after session activation to     terminate the client. (CVE-2026-121406)

    FreeRDP before 3.32.2 contains a denial of service vulnerability in the shadow server's     remdesk_server_thread that allows authenticated clients to crash the process via an inverted PDU length     check. Attackers can send an 8192-byte remdesk payload declaring an eight-byte PDU length to trigger a     fatal Stream_Seek assertion, aborting the server and dropping sessions. (CVE-2026-121407)

    FreeRDP before 3.32.2 contains a use-after-free in the urbdrc USB redirection channel because     FindChannelById returns a channel pointer without a reference and the control-channel close path does not     take the device manager's loading_lock. A malicious RDP server can send a control-channel CLOSE_REQUEST     while the client announces a USB device, freeing the channel before the announcement thread reads     channel->Write and crashing the client. (CVE-2026-121408)

    FreeRDP before 3.32.2 contains a denial of service vulnerability that allows malicious servers or     unauthenticated peers to abort clients or proxies via oversized X.224 routing tokens. Attackers can send     an oversized LoadBalanceInfo in a Server Redirection PDU, or a 240247 byte token to a FixedTarget     freerdp-proxy, triggering a tpdu_write_header assertion that crashes the process. (CVE-2026-121409)

    FreeRDP before 3.32.2 contains a denial of service vulnerability in the RDPGFX ALPHA WIRETOSURFACE_2     handler that fails to validate zero surface dimensions. A malicious RDP server can send a crafted     WIRETOSURFACE_2 PDU with zero width and height, triggering an assertion or division by zero that     terminates the client session. (CVE-2026-121410)

    FreeRDP from 3.0.0 before 3.32.2 contains an uncontrolled resource consumption vulnerability in the proxy     that lets connected clients retain heap memory via intercepted DVC message reassembly. Attackers can     declare a large DATA_FIRST length and keep sending fragments without completing the message, growing proxy     memory proportional to traffic and degrading service. (CVE-2026-121412)

    FreeRDP before 3.32.2 does not check the product of surface dimensions in gdi_CreateSurface when handling     an RDPGFX CREATE_SURFACE PDU, causing an integer wrap and heap buffer overflow on 32-bit builds and an     approximately 4 GiB allocation on 64-bit builds. A malicious RDP server can send a CREATE_SURFACE PDU with     width and height 32766 to a connecting client to corrupt heap memory or cause a denial of service.
    (CVE-2026-121950)

    FreeRDP before 3.32.2 has a heap out-of-bounds write in the planar codec because     freerdp_bitmap_planar_context_reset commits new dimensions before buffer reallocation succeeds, and a     failed ResetGraphics is only logged. A malicious RDP server can send an oversized ResetGraphics PDU, then     a GFX PLANAR command, to corrupt client heap memory and crash the client. (CVE-2026-121954)

    FreeRDP before 3.32.2 contains an infinite loop vulnerability in websocket_context_read that fails to     handle a zero BIO result with payload outstanding. A malicious RD Gateway can send a truncated WebSocket     frame followed by a TLS close_notify, causing a client thread to spin and consume CPU until killed.
    (CVE-2026-121959)

    FreeRDP before 3.32.2 contains a use-after-free vulnerability in the freerdp-proxy DRDYNVC tracker when     intercepting the drdynvc channel. A malicious target server can repeatedly send CREATE_REQUEST_PDU for an     active channel id, racing front DATA handling to free a borrowed context and crash the proxy process.
    (CVE-2026-121961)

    FreeRDP before 3.32.2 contains a use-after-free vulnerability in the asynchronous dynamic rdpsnd channel     that allows malicious RDP servers to trigger freed callback access by closing the channel with queued     audio PDUs. Attackers can send a training PDU then close the channel so the playback thread reads the     freed callback in rdpsnd_virtual_channel_write, crashing the client. (CVE-2026-121963)
