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。

  - 之前的 Mistune 3.3.0 在 parse_link_text 中包含低效的算法复杂性漏洞，允许远程攻击者通过不平衡的方括号造成拒绝服务。攻击者可以向 mistune.html（） 提交包含长运行不匹配括号的 markdown，触发重复的前向扫描，使工作进程停止数分钟。（CVE-2026-115347）

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 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。

  - Mistune before 3.3.0 在 parse_link_text 中包含一個低效的演算法複雜度弱點，允許遠端攻擊者透過不平衡的方括號造成拒絕服務。攻擊者可以將包含長時間不相符括號的 Markdown 提交給 mistune.html（），觸發重複的前向掃描，使背景工作程序停頓幾分鐘。（CVE-2026-115347）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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。

  - Mistune before 3.3.0 には、parse_link_text の非効率的なアルゴリズム複雑性の脆弱性が含まれており、リモートの攻撃者がバランスの崩れた角括弧を通じてサービス拒否を引き起こす可能性があります。攻撃者が、一致しない括弧の長時間を含むマークダウンを mistune.html() に送信し、転送スキャンを繰り返して数分間ワーカープロセスを停止させる可能性があります。(CVE-2026-115347)

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 remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-ea39a303cf advisory.

    Update to 3.3.4


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

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

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

  - Mistune before 3.3.0 contains an inefficient algorithmic complexity vulnerability in parse_link_text that     allows remote attackers to cause denial of service through unbalanced square brackets. Attackers can     submit markdown containing long runs of unmatched brackets to mistune.html(), triggering repeated forward     scans that stall worker processes for minutes. (CVE-2026-115347)

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

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-340793a2f1 advisory.

    Update to 3.3.4

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

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-3386 advisory.

    Mistune before 3.3.0 contains an inefficient algorithmic complexity vulnerability in parse_link_text that     allows remote attackers to cause denial of service through unbalanced square brackets. Attackers can     submit markdown containing long runs of unmatched brackets to mistune.html(), triggering repeated forward     scans that stall worker processes for minutes. (CVE-2026-115347)

    Mistune before 3.3.0 contains an algorithmic complexity vulnerability in the inline link parser that     allows unauthenticated attackers to exhaust CPU by submitting long runs of unmatched '[' characters.
    Attackers can send small markdown payloads that trigger O(N^2) parse_link_text and parse_link_label     probing, occupying rendering workers for 30+ seconds per 16 KB input. (CVE-2026-115352)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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