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 248946, バグ 269548.

Mitre の CVE 辞書: CVE-2004-0150.

詳細:

このセキュリティ勧告は、DSA 458-2 の改定版で、gethostbyaddr ルーチンで発生する問題を修正したものです。

元の勧告によると:

Sebastian Schmidt さんにより、Python の getaddrinfo 関数にバッファオーバフローバグが発見されました。この欠陥は、リモートの攻撃者が DNS 経由で提供した IPv6 アドレスが、スタック上のメモリを上書きしてしまうというものです。

このバグは、python 2.2 と 2.2.1 にのみ存在し、IPv6 サポートが無効になっている時のみに問題になります。Debian woody の python2.2 パッケージはこの条件に当てはまります (「python」パッケージは当てはまりません)。

安定版 (stable) ディストリビューション (woody) では、この問題はバージョン 2.2.1-4.6 で修正されています。

テスト版 (testing) と不安定版 (unstable) ディストリビューション (sarge と sid) には、この問題はありません。

直ちに python2.2 関連のパッケージをアップグレードすることをお勧めします。

修正:

Debian GNU/Linux 3.0 (woody)
