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-2009-0692, CVE-2009-1892.
CERT の脆弱性リスト、勧告および付加情報: VU#410676.
詳細:

ISC の DHCP 実装に、リモートから攻撃可能な複数の問題が発見されました。

  • CVE-2009-0692

    dhclient が過度に長いサブネットマスクオプションを正しく処理できない ため、スタックベースのバッファオーバフローによる任意のコードの実行に 繋がることが発見されました。

  • CVE-2009-1892

    Christoph Biedl さんにより、DHCP サーバが、サーバ設定で "dhcp-client-identifier" と "hardware ethernet" によるホスト定義を混 在させていた場合、特定の well-form なリクエストを受けた場合に終了す ることが発見されました。この欠陥は lenny の dhcp3-server と dhcp3-server-ldap にのみ影響します。

旧安定版 (oldstable) ディストリビューション (etch) では、これらの問題は バージョン 3.0.4-13+etch2 で修正されています。

安定版 (stable) ディストリビューション (lenny) では、この問題はバージョ ン 3.1.1-6+lenny2 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、これらの問題は近 く修正予定です。

直ぐに dhcp3 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)
