報告日時:
2005-04-01
影響を受けるパッケージ:
krb5
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-2005-0468, CVE-2005-0469.
CERT の脆弱性リスト、勧告および付加情報: VU#341908, VU#291924.
詳細:

telnet クライアント中に、 接続先のデーモンが悪意を持っている場合に攻撃される可能性があるという問題が、 複数発見されています。Common Vulnerabilities and Exposures プロジェクトでは以下の問題を認識しています:

  • CAN-2005-0468

    Gaël Delalleau さんが、env_opt_add() 関数中にバッファオーバフローを発見しました。これにより、 攻撃者によってリモートから任意のコードを実行される恐れがあります。

  • CAN-2005-0469

    Gaël Delalleau さんが、telnet クライアントの LINEMODE サブオプションの取り扱いにバッファオーバフローを発見しました。 これは、悪意を持ったサーバに接続した際、 任意のコードを実行されてしまう恐れがあるというものです。

安定版ディストリビューション (stable、コードネーム woody) では、これらの問題はバージョン 1.2.4-5woody8 で修正されています。

不安定版ディストリビューション (unstable、コードネーム sid) では、これらの問題はバージョン 1.3.6-1 で修正されています。

krb5 パッケージのアップグレードをお勧めします。

修正:

Debian GNU/Linux 3.0 (woody)
