Vulnerability in github.com/containers/podman/v4 (CVE-2022-27649)

Summary

Vulnerability in github.com/containers/podman/v4 (CVE-2022-27649). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 4.0.3 or later.

Original description

The description as published by the source.

A bug was found in Podman where containers were created 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.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'github.com/containers/podman/v4' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で github.com/containers/podman/v4 を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply patch patch 
    Upgrade github.com/containers/podman/v4 to 4.0.3

    ステージング環境で 4.0.3 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  3. 3
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
