There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Synapse is an open source Matrix homeserver implementation. Prior to 1.152.1, in federated rooms,
    malicious homeservers can craft room events in such a way that prevents Synapse from providing full
    history to paginating clients. Clients could therefore fail to display room history. This vulnerability is
    fixed in 1.152.1. (CVE-2026-45076)

  - Synapse is an open source Matrix homeserver implementation. Prior to 1.152.1, local authenticated users
    can cause Synapse to starve other requests of CPU and lead to other requests failing, causing other users
    to be denied service. This vulnerability is fixed in 1.152.1. (CVE-2026-45078)

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。

  - Synapse 是開放原始碼 Matrix 主伺服器實作。之前 1.152.1，在同盟會議室中，惡意起始伺服器可以製作會議室事件，以防止 Synapse 將完整歷程記錄提供給分頁用戶端。因此，用戶端可能無法顯示會議室歷程記錄。此弱點已在 1.152.1 中修正。(CVE-2026-45076)

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。

  - Synapse 是开源的 Matrix 主服务器实现。以前 1.152.1，在联合会议室中，恶意家庭服务器可以阻止 Synapse 向分页客户端提供完整历史记录的方式构建会议室事件。因此，客户端可能无法显示聊天室历史记录。此漏洞已在 1.152.1 中修复。(CVE-2026-45076)

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。

  - Synapseは、オープンソースのMatrixホームサーバー実装です。1.152.1より前は、フェデレーションルームでは、悪意のあるホームサーバーが、Synapseがページ分割クライアントに完全な履歴を提供できないように、ルームイベントを作成する可能性があります。そのため、クライアントがルーム履歴を表示できない可能性があります。この脆弱性は 1.152.1 で修正されました。(CVE-2026-45076)

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.

  - Synapse is an open source Matrix homeserver implementation. Prior to 1.152.1, in federated rooms,     malicious homeservers can craft room events in such a way that prevents Synapse from providing full     history to paginating clients. Clients could therefore fail to display room history. This vulnerability is     fixed in 1.152.1. (CVE-2026-45076)

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