DSA-1616-2 clamav -- サービス拒否攻撃

報告日時:
2008-07-26
影響を受けるパッケージ:
clamav
危険性:
あり
参考セキュリティデータベース:
Debian バグ追跡システム: バグ 490925.
Mitre の CVE 辞書: CVE-2008-2713, CVE-2008-3215.
詳細:

Damian Put さんにより、ClamAV アンチウィルスツールキットの、Petite 圧縮 形式の Win32 実行ファイルパーザに欠陥が発見されました。この欠陥により、 不正なメモリアクセスが発生し、攻撃者から不正に細工された Petite 圧縮形 式のバイナリをスキャンさせることにより clamav をクラッシュ可能です。こ れは clamav がメールサーバと組み合わせて使われている場合などではシステ ムがファイルを開くのに失敗するため、以降のウィルス攻撃が可能です。

この勧告の以前のバージョンは、正しくビルドされておらず、目的の訂正を落 としていたパッケージを参照していました。この問題は、勧告の -2 リビジョ ンで参照されるパッケージで修正されました。

The Common Vulnerabilities and Exposures project は以下の問題を、 CVE-2008-2713 および CVE-2008-3215 として認識しています。.

安定版 (stable) ディストリビューション (etch) では、この問題はバージョン 0.90.1dfsg-3.1+etch14 で修正されています。

不安定版 (unstable) ディストリビューション (sid) では、これらの問題はバ ージョン 0.93.1.dfsg-1.1 で修正されています。

直ぐに clamav パッケージをアップグレードすることを勧めます。

修正:

Debian GNU/Linux 4.0 (etch)
