DSA-197-1 courier -- バッファオーバーフロー
- 報告日時:
- 2002-11-15
- 影響を受けるパッケージ:
- courier
- 危険性:
- あり
- 参考セキュリティデータベース:
- Mitre の CVE 辞書: CVE-2002-1311.
- 詳細:
-
Courier sqwebmail (ローカルのメールボックスに対して認証されたアクセス を提供する CGI プログラム) パッケージに問題が発見されました。 このプログラムは、特定の条件のもとで権限を落とすのが遅すぎるため、 ローカルのシェルの実行権限をもつユーザによって sqwebmail バイナリ を実行でき、ローカルのファイルシステムにある任意のファイルを 読むことができてしまいます。
この問題は、現安定版 (stable)(woody) ではバージョン 0.37.3-2.3 で、 不安定版 (unstable)(sid) ではバージョン 0.40.0-1 で修正されています。 なお、旧安定版 (potato) は Courier sqwebmail パッケージ群を含みません。
courier-sslパッケージ群も、sqwebmail パッケージを 曝さないため、この問題の影響を受けません。sqwebmail を早急にアップグレードすることをお勧めします。
- 修正:
-
