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。

  - 攻擊者可傳送特製的 DNS-over-HTTPS 要求，其中包含密碼編譯上無效的 SIG（0） 記錄，然後過早關閉傳輸連線，藉此導致 'named' 中止。此問題影響 BIND 9 版本 9.20.09.20.27（至 、 9.21.09.21.25和 9.20.9-S1 至 9.20.27-S1）。
    (CVE-2026-77692)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - 攻击者可通过发送具有密码无效 SIG（0） 记录的构建的 DNS-over-HTTPS 请求然后永久关闭传输连接，来造成“named”中止。此问题影响 BIND 9 到 9.20.27到 9.20.9-S1 到 9.20.27-S1 9.21.259.21.0 的版本9.20.0。
    (CVE-2026-77692)

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。

  - 攻撃者は、暗号的に無効な SIG(0) レコードを含む細工された DNS-over-HTTPS リクエストを送信し、続いてトランスポート接続を時期尚早に閉じることで、「named」を中止させる可能性があります。この問題は、バージョン 9.20.0 から 9.20.27、 9.21.0 から 9.21.25、9.20.9-S1 から 9.20.27-S1 までの BIND 9 に影響を与えます。
    (CVE-2026-77692)

Nessus は、ベンダーによって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.

  - An attacker can cause `named` to abort by sending a crafted DNS-over-HTTPS request with a     cryptographically invalid SIG(0) record, and then closing the transport connection prematurely. This issue     affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1.
    (CVE-2026-77692)

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

The version of ISC BIND running on the remote host is 9.20.0 through 9.20.27 or 9.21.0 through 9.21.25. Supported Preview Edition releases 9.20.9-S1 through 9.20.27-S1 are also affected. It is, therefore, affected by a vulnerability :

  - An attacker can cause named to abort by sending a crafted DNS-over-HTTPS request with a cryptographically     invalid SIG(0) record, and then closing the transport connection prematurely. A successful attack may result     in abnormal program termination and a denial-of-service. (CVE-2026-77692)

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

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6505 advisory.

    Several vulnerabilities were discovered in BIND, a DNS server implementation,     which may result in denial of service or cache poisoning.

    For the stable distribution (trixie), these problems have been fixed in     version 1:9.20.29-1~deb13u1.

    We recommend that you upgrade your bind9 packages.

    For the detailed security status of bind9 please refer to     its security tracker page at:
