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

  - containerd is an open source container runtime. On installations using SELinux, such as EL8 (CentOS,
    RHEL), Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime
    interface (CRI), an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any
    privileged, regular file on disk for complete read/write access (sans delete). Such is achieved by placing
    the in-container location of the hostPath volume mount at either `/etc/hosts`, `/etc/hostname`, or
    `/etc/resolv.conf`. These locations are being relabeled indiscriminately to match the container process-
    label which effectively elevates permissions for savvy containers that would not normally be able to
    access privileged host files. This issue has been resolved in version 1.5.9. Users are advised to upgrade
    as soon as possible. (CVE-2021-43816)

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。

  - containerd 是一種開放原始碼的容器執行階段。在使用 SELinux 的安裝項目中例如 EL8 (CentOS、RHEL)、Fedora 或 SUSE MicroOS並將自 v1.5.0-beta.0 起的 containerd 做為備份容器運行時間介面 (CRI) 排程到節點的無權限 pod 可能會系結掛載透過 hostPath 磁碟區完整讀取/寫入存取磁碟上任何有權限的一般檔案 (無刪除)。將 hostPath 磁碟區的容器內位置掛載在 `/etc/hosts`、`/etc/hostname` 或 `/etc/resolv.conf`即可達到此目的。這些位置被不加選擇地重新標記以符合容器 process-label這可有效提升通常無法存取具權限主機檔案之精明容器的權限。此問題已在 1.5.9 版中獲得解決。建議使用者盡快升級。 (CVE-2021-43816)

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。

  - containerd 是一个开源容器运行时。在使用 SELinux 的安装中例如 EL8CentOS、RHEL、Fedora 或 SUSE MicroOS如果使用从 v1.5.0-beta.0 起的 containerd 作为后备容器运行时接口 (CRI)计划到节点的非特权 pod 可能绑定挂载通过 hostPath 卷对磁盘上的任何特权常规文件进行完整的读/写访问无删除。通过将 hostPath 卷挂载的容器内位置放置在“/etc/hosts”、“/etc/hostname”或“/etc/resolv.conf”中可以实现此目的。这些位置会不加区分地重新标记以匹配容器进程标签这可有效提升通常无法访问特权主机文件的智能容器的权限。此问题已在版本 1.5.9 中得到解决。建议用户尽快升级。 (CVE-2021-43816)

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。

  - containerd は、オープンソースのコンテナランタイムです。EL8CentOS、RHEL、Fedora、SUSE MicroOS などの SELinux を使用し、v1.5.0-beta.0 以降の containerd をバッキングコンテナランタイムインターフェイスCRIとして使用するインストールでは、ノードにスケジュールされている権限のないポッドがマウントをバインドする可能性があります。 、hostPath ボリュームを介して、完全な読み取り/書き込みアクセスが可能なディスク上の任意の通常ファイル (sans delete)。これは、hostPath ボリュームマウントのコンテナ内のロケーションを「/etc/hosts」、「/etc/hostname」、または「/etc/resolv.conf」のいずれかに配置することで実現されます。これらの場所は、コンテナプロセスラベルに合わせて無差別に再ラベル付けされ、通常は権限のあるホストファイルにアクセスできない可能性のある savvy コンテナの権限を効果的に昇格します。この問題はバージョン1.5.9で解決済みです。ユーザーはなるべく早くアップグレードすることをお勧めします。CVE-2021-43816

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。

An update of the fuse package has been released.

    ```

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.
