  - runc: 継承可能な機能の不適切な処理 (CVE-2022-29162)

  - Buildah コンテナエンジンの補助グループ処理が不適切なため、攻撃者が影響を受けるコンテナに直接アクセスし、補助グループを使用してアクセス許可を設定し、そのコンテナでバイナリ コードを実行できる場合、機密情報を漏洩させたりデータを改ざんしたりする可能性があります。(CVE-2022-2990)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。

リモートホストにインストールされている docker のバージョンは、20.10.7-5より前のものです。したがって、ALAS2ECS-2023-025のアドバイザリに記載されている脆弱性の影響を受けます。

  - OCI Distribution Spec プロジェクトは、コンテンツの配布を容易にし、標準化する API プロトコルを定義しています。バージョン 1.0.0以前の OCI Distribution Specification では、プッシュおよびプル操作中にドキュメントのタイプを判断するために Content-Type ヘッダーのみが使用されていました。manifests と layers の両方のフィールドを含むドキュメントは、付随する Content-Type ヘッダーがない場合、マニフェストまたはインデックスとして解釈される可能性があります。Content-Type ヘッダーが同じダイジェストの 2 つのプルの間に変更された場合、クライアントは結果のコンテンツを異なる方法で解釈する可能性があります。OCI Distribution Specification が更新され、マニフェストまたはインデックスに存在する mediaType の値が、プッシュおよびプル操作中に使用される Content-Type ヘッダーと一致することが要求されるようになりました。仕様のバージョン 1.0.1に更新できない場合、レジストリからプルするクライアントは、Content-Type ヘッダーを信頼せず、manifests と layers の両方のフィールド、または manifests と config の両方のフィールドを含むあいまいなドキュメントを拒否する可能性があります。(CVE-2021-41190)

リモートのRocky Linux 8ホストには、RLSA-2022:7457アドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

  - runc は、OCI 仕様にしたがって Linux でコンテナを生成および実行するための CLI ツールです。バージョン 1.1.2より前の runc でバグが見つかりました。「runc exec --cap」が空ではない継承可能な Linux プロセス機能を持つプロセスを作成し、非定型の Linux 環境を作成し、execve (2) 中に継承可能なファイル機能を持つプログラムが、これらの機能を許可された設定に引き上げてしまうことが可能でした。継承可能な設定には、コンテナの境界設定に含まれるよりも多くの機能は含まれていないため、このバグはコンテナセキュリティサンドボックスに影響を与えませんでした。このバグは runc 1.1.2で修正されました。この修正では、「runc exec --cap」の動作が変更されるため、実行されるプロセスに付与された追加機能 (「--cap」引数で指定) に継承可能な機能が含まれなくなります。さらに、「runc spec」が、作成されたサンプル OCI 指定 (「config.json」) ファイルで継承可能な機能を設定しないように変更されています。(CVE-2022-29162)

  - 1.15.15より前の Go および1.16.7より前の1.16.xでは、競合状態があり、ErrAbortHandler の中止時に、net/http/httputil ReverseProxy パニックに至る可能性があります。(CVE-2021-36221)

  - CRI-O に脆弱性が見つかりました。これは、Kube API にアクセスできるユーザーに対して、ノードでメモリまたはディスク領域の枯渇を引き起こす可能性があります。ExecSync リクエストは、コンテナでコマンドを実行し、コマンドの出力をログに記録します。この出力は、コマンドの実行後に CRI-O によって読み取られ、コマンドの出力に対応するファイル全体を読み取る方法で読み取られます。したがって、コマンドの出力が大きい場合、CRI-O がコマンドの出力を読み取るときに、ノードのメモリまたはディスク領域を使い果たす可能性があります。この脆弱性が最大の脅威となるのは、システムの可用性です。(CVE-2022-1708)

  - Buildah コンテナエンジンの補助グループ処理が不適切なため、攻撃者が影響を受けるコンテナに直接アクセスし、補助グループを使用してアクセス許可を設定し、そのコンテナでバイナリ コードを実行できる場合、機密情報を漏洩させたりデータを改ざんしたりする可能性があります。(CVE-2022-2990)

The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-7457 advisory.

    - fix CVE-2022-2990

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

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

According to the versions of the docker-engine package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Moby is an open-source project created by Docker to enable software containerization. A bug was found in     Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container     can result in Unix file permission changes for existing files in the host's filesystem, widening access to     others. This bug does not directly allow files to be read, modified, or executed without an additional     cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this     version as soon as possible. Running containers do not need to be restarted. (CVE-2021-41089)

  - Moby is an open-source project created by Docker to enable software containerization. A bug was found in     Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with     insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory     contents and execute programs. When containers included executable programs with extended permission bits     (such as `setuid`), unprivileged Linux users could discover and execute those programs. When the UID of an     unprivileged Linux user on the host collided with the file owner or group inside a container, the     unprivileged Linux user on the host could discover, read, and modify those files. This bug has been fixed     in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running     containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade     limit access to the host to trusted users. Limit access to host volumes to trusted containers.
    (CVE-2021-41091)

  - Docker CLI is the command line interface for the docker container runtime. A bug was found in the Docker     CLI where running `docker login my-private-registry.example.com` with a misconfigured configuration file     (typically `~/.docker/config.json`) listing a `credsStore` or `credHelpers` that could not be executed     would result in any provided credentials being sent to `registry-1.docker.io` rather than the intended     private registry. This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as     soon as possible. For users unable to update ensure that any configured credsStore or credHelpers entries     in the configuration file reference an installed credential helper that is executable and on the PATH.
    (CVE-2021-41092)

  - The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution     of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone     was used to determine the type of document during push and pull operations. Documents that contain both     manifests and layers fields could be interpreted as either a manifest or an index in the absence of an     accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a     client may interpret the resulting content differently. The OCI Distribution Specification has been     updated to require that a mediaType value present in a manifest or index match the Content-Type header     used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type     header and reject an ambiguous document that contains both manifests and layers fields or manifests     and config fields if they are unable to update to version 1.0.1 of the spec. (CVE-2021-41190)

  - runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. A bug     was found in runc prior to version 1.1.2 where `runc exec --cap` created processes with non-empty     inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with     inheritable file capabilities to elevate those capabilities to the permitted set during execve(2). This     bug did not affect the container security sandbox as the inheritable set never contained more capabilities     than were included in the container's bounding set. This bug has been fixed in runc 1.1.2. This fix     changes `runc exec --cap` behavior such that the additional capabilities granted to the process being     executed (as specified via `--cap` arguments) do not include inheritable capabilities. In addition, `runc     spec` is changed to not set any inheritable capabilities in the created example OCI spec (`config.json`)     file. (CVE-2022-29162)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0334-1 advisory.

    (CVE-2021-41092)

  - containerd is an open source container runtime with an emphasis on simplicity, robustness and portability.
    A bug was found in containerd where container root directories and some plugins had insufficiently     restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and     execute programs. When containers included executable programs with extended permission bits (such as     setuid), unprivileged Linux users could discover and execute those programs. When the UID of an     unprivileged Linux user on the host collided with the file owner or group inside a container, the     unprivileged Linux user on the host could discover, read, and modify those files. This vulnerability has     been fixed in containerd 1.4.11 and containerd 1.5.7. Users should update to these version when they are     released and may restart containers or update directory permissions to mitigate the vulnerability. Users     unable to update should limit access to the host to trusted users. Update directory permission on     container bundles directories. (CVE-2021-41103)

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0187-1 advisory.

  - Rootless containers run with Podman, receive all traffic with a source IP address of 127.0.0.1 (including     from remote hosts). This impacts containerized applications that trust localhost (127.0.01) connections by     default and do not require authentication. This issue affects Podman 1.8.0 onwards. (CVE-2021-20199)

  - An improper limitation of path name flaw was found in containernetworking/cni in versions before 0.8.1.
    When specifying the plugin to load in the 'type' field in the network configuration, it is possible to use     special elements such as ../ separators to reference binaries elsewhere on the system. This flaw allows     an attacker to execute other existing binaries other than the cni plugins/types, such as 'reboot'. The     highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
    (CVE-2021-20206)

  - A flaw was found in podman. The `podman machine` function (used to create and manage Podman virtual     machine containing a Podman process) spawns a `gvproxy` process on the host system. The `gvproxy` API is     accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an     attacker can potentially use the `gvproxy` API to forward ports on the host to ports in the VM, making     private services on the VM accessible to the network. This issue could be also used to interrupt the     host's services by forwarding all ports to the VM. (CVE-2021-4024)

  - The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution     of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone     was used to determine the type of document during push and pull operations. Documents that contain both     manifests and layers fields could be interpreted as either a manifest or an index in the absence of an     accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a     client may interpret the resulting content differently. The OCI Distribution Specification has been     updated to require that a mediaType value present in a manifest or index match the Content-Type header     used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type     header and reject an ambiguous document that contains both manifests and layers fields or manifests     and config fields if they are unable to update to version 1.0.1 of the spec. (CVE-2021-41190)

  - A flaw was found in Podman, where containers were started incorrectly with non-empty default permissions.
    A vulnerability was found in Moby (Docker Engine), where containers were started incorrectly with non-     empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with     inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
    (CVE-2022-27649)

  - An incorrect handling of the supplementary groups in the Podman container engine might lead to the     sensitive information disclosure or possible data modification if an attacker has direct access to the     affected container where supplementary groups are used to set access permissions and is able to execute a     binary code in that container. (CVE-2022-2989)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2025:02282-1 advisory.

    Update to umoci v0.5.0. Upstream changelog is available from

      <https://github.com/opencontainers/umoci/releases/tag/v0.5.0> bsc#1243388

    A security flaw was found in the OCI image-spec, where it is possible to     cause a blob with one media-type to be interpreted as a different media-type.
    As umoci is not a registry nor does it handle signatures, this vulnerability     had no real impact on umoci but for safety we implemented the now-recommended     media-type embedding and verification. CVE-2021-41190
