請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

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。

  - 之前和1.0.0之前13.0.013.0.5在 Prosody 0.12.6 中發現了一個問題。拒絕服務可能是透過 XML 剖析資源從未經驗證的連線放大所導致的記憶體耗盡而發生。（CVE-2026-43507）

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。

  - Prosody 之前0.12.6和1.0.0之前13.0.5版本13.0.0中发现一个问题。拒绝服务可通过从未经认证的连接放大 XML 解析资源造成的内存耗尽而发生。（CVE-2026-43507）

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

  - An issue was discovered in Prosody before 0.12.6 and 1.0.0 through 13.0.0 before 13.0.5. A Denial of     Service can occur via memory exhaustion caused by XML parsing resource amplification from unauthenticated     connections. (CVE-2026-43507)

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-2026-36c53b9ca8 advisory.
