Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - FreeRDP 之前 3.32.0 在 general_LumaToYUV444 和 general_ChromaV2ToYUV444 中包含一個用戶端堆積越界寫入弱點，允許惡意RDP伺服器損毀用戶端記憶體。攻擊者可以發送 RDPGFX AVC444 或 AVC444v2 框架，其奇數高度區域矩形以表面高度結束，以寫入過去的 U/V 平面，從而實現堆積損毀和潛在的程式碼執行。（CVE-2026-111382）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 之前 3.32.0 的 FreeRDP 在 general_LumaToYUV444 和 general_ChromaV2ToYUV444 中包含客户端堆越界写入漏洞，可允许恶意 RDP 服务器损坏客户端内存。攻击者可能会发送以表面高度结尾的奇数高度区域矩形的 RDPGFX AVC444 或 AVC444v2 帧，以写入越过 U/V 平面，进而造成堆损坏和可能的代码执行。（CVE-2026-111382）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - 3.32.0 より前のFreeRDPには、general_LumaToYUV444およびgeneral_ChromaV2ToYUV444にクライアント側のヒープ領域外書き込みの脆弱性が含まれており、悪意のあるRDPサーバーがクライアントメモリを破損する可能性があります。攻撃者が、表面の高さで終わる奇数高さの領域長方形を持つ RDPGFX AVC444 または AVC444v2 フレームを送信し、U/V プレーンを超えて書き込み、ヒープ破損および潜在的なコード実行を引き起こす可能性があります。(CVE-2026-111382)

Nessus は、ベンダーから報告されたパッケージの存在に依存していることに注意してください。

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

  - FreeRDP before 3.32.0 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-2026-111382)

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

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:1194 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2026-111382:
    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-2026-111381:
    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-2026-111378:
    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-2026-111377:
    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:
    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-2026-109242:
    FreeRDP before 3.0.0 and 3.6.0 before 3.32.0 renders uninitialized heap memory from un-decoded progressive     tiles because the tile->current buffer is allocated without zeroing. A malicious RDP server can send a     crafted WBT_TILE_FIRST then WBT_TILE_UPGRADE sequence to paint heap bytes onscreen or abort the client     process.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
