There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Underscore.js is a utility-belt library for JavaScript. Prior to 1.13.8, the _.flatten and _.isEqual
    functions use recursion without a depth limit. Under very specific conditions, detailed below, an attacker
    could exploit this in a Denial of Service (DoS) attack by triggering a stack overflow. Untrusted input
    must be used to create a recursive datastructure, for example using JSON.parse, with no enforced depth
    limit. The datastructure thus created must be passed to _.flatten or _.isEqual. In the case of _.flatten,
    the vulnerability can only be exploited if it is possible for a remote client to prepare a datastructure
    that consists of arrays at all levels AND if no finite depth limit is passed as the second argument to
    _.flatten. In the case of _.isEqual, the vulnerability can only be exploited if there exists a code path
    in which two distinct datastructures that were submitted by the same remote client are compared using
    _.isEqual. For example, if a client submits data that are stored in a database, and the same client can
    later submit another datastructure that is then compared to the data that were saved in the database
    previously, OR if a client submits a single request, but its data are parsed twice, creating two non-
    identical but equivalent datastructures that are then compared. Exceptions originating from the call to
    _.flatten or _.isEqual, as a result of a stack overflow, are not being caught. This vulnerability is fixed
    in 1.13.8. (CVE-2026-27601)

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

  - Underscore.js 是 JavaScript 的實用程式庫。在之前 1.13.8，_.flatten 和 _.isEqual 函式使用遞迴，沒有深度限制。在非常特殊的情況下 （詳見下文），攻擊者可以透過觸發堆疊溢位來在拒絕服務 （DoS） 攻擊中利用這一點。必須使用不受信任的輸入來建立遞迴資料結構，例如使用 JSON.parse，且沒有強制深度限制。如此建立的資料結構必須傳遞給 _.flatten 或 _.isEqual。在 _.flatten 的情況下，只有在遠端用戶端可以準備由所有層級陣列所組成的資料結構，而且沒有將有限深度限制傳遞為第二個引數時，才能惡意探索弱點
    _.flatten。在 _.isEqual 的情況下，只有在存在程式碼路徑時，才能惡意探索弱點，其中使用比較相同遠端用戶端所提交的兩個不同資料結構
    _.isEqual。例如，如果用戶端提交儲存在資料庫中的資料，而相同的用戶端稍後可以提交另一個資料結構，然後與先前儲存在資料庫中的資料進行比較，或者如果用戶端提交單一要求，但其資料會剖析兩次，建立兩個不相同但對等的資料結構，然後進行比較。源自對
    _.flatten 或 _.isEqual，因為堆疊溢位，不會被攔截。此弱點已在 1.13.8 中修復。(CVE-2026-27601)

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。

  - Underscore.js 是适用于 JavaScript 的实用工具库。在之前 1.13.8，_.flatten 和 _.isEqual 函数使用没有深度限制的递归。在非常特定的情况下（如下详述），攻击者可通过触发堆栈溢出在拒绝服务 （DoS） 攻击中利用此漏洞。必须使用不受信任的输入创建递归数据结构，例如使用 JSON.parse，没有强制深度限制。由此创建的数据结构必须传递给 _.flatten 或 _.isEqual。就 _.flatten 而言，只有在远程客户端可准备由各级数组所构成的数据结构，并且未将有限深度限制作为第二个参数传递至
    _.flatten。就 _.isEqual 而言，仅当存在一个代码路径，其中使用比较由相同远程客户端提交的两个不同数据结构时，才能利用此漏洞
    _.isEqual。例如，如果客户端提交存储在数据库中的数据，并且同一客户端稍后可以提交另一个数据结构，然后将该数据结构与之前保存在数据库中的数据进行比较，或者如果客户端提交单个请求，但其数据被解析两次，创建两个不相同但等效的数据结构，然后进行比较。源自对
    由于堆栈溢出，未捕获 _.flatten 或 _.isEqual。此漏洞已在 1.13.8 中修复。(CVE-2026-27601)

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。

  - Underscore.js は JavaScript 用のユーティリティベルトライブラリです。1.13.8より前の _.flatten 関数と _.isEqual 関数は、深さ制限なしで再帰を使用します。非常に特殊な状況(以下に詳述)で、攻撃者はこれをサービス拒否(DoS)攻撃に悪用し、スタックオーバーフローを発生させる可能性があります。信頼できない入力を使用して、たとえば JSON.parse を使用して、強制された深さ制限なしで再帰データ構造を作成する必要があります。このようにして作成されたデータ構造は、_.flatten または _.isEqual に渡される必要があります。_.flatten の場合、この脆弱性は、リモートクライアントが、すべてのレベルの配列で構成されるデータ構造を準備できる場合、および 2 番目の引数として渡される有限の深さ制限がない場合にのみ悪用される可能性があります。
    _.flatten。_.isEqualの場合、この脆弱性は、同じリモートクライアントによって送信された2つの異なるデータ構造が、
    _.isEqualです。たとえば、クライアントがデータベースに格納されているデータを送信し、同じクライアントが後で別のデータ構造を送信し、それを以前データベースに保存されたデータと比較できる場合、またはクライアントが 1 つの要求を送信したが、そのデータが 2 回解析され、2 つの同一ではないが同等のデータ構造が作成されて比較される場合などです。に対する呼び出しに由来する例外
    _.flatten または _.isEqual は、スタックオーバーフローの結果として、キャッチされていません。この脆弱性は 1.13.8 で修正されました。(CVE-2026-27601)

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

  - Underscore.js is a utility-belt library for JavaScript. Prior to 1.13.8, the _.flatten and _.isEqual     functions use recursion without a depth limit. Under very specific conditions, detailed below, an attacker     could exploit this in a Denial of Service (DoS) attack by triggering a stack overflow. Untrusted input     must be used to create a recursive datastructure, for example using JSON.parse, with no enforced depth     limit. The datastructure thus created must be passed to _.flatten or _.isEqual. In the case of _.flatten,     the vulnerability can only be exploited if it is possible for a remote client to prepare a datastructure     that consists of arrays at all levels AND if no finite depth limit is passed as the second argument to
    _.flatten. In the case of _.isEqual, the vulnerability can only be exploited if there exists a code path     in which two distinct datastructures that were submitted by the same remote client are compared using
    _.isEqual. For example, if a client submits data that are stored in a database, and the same client can     later submit another datastructure that is then compared to the data that were saved in the database     previously, OR if a client submits a single request, but its data are parsed twice, creating two non-     identical but equivalent datastructures that are then compared. Exceptions originating from the call to
    _.flatten or _.isEqual, as a result of a stack overflow, are not being caught. This vulnerability is fixed     in 1.13.8. (CVE-2026-27601)
