DSA-262-1 samba -- リモートからの攻撃

報告日時:
2003-03-15
影響を受けるパッケージ:
samba
危険性:
あり
参考セキュリティデータベース:
(SecurityFocus の) Bugtraq データベース: BugTraq ID 7107, BugTraq ID 7106.
Mitre の CVE 辞書: CVE-2003-0085, CVE-2003-0086.
詳細:

SuSE セキュリティ監査チームの Sebastian Krahmer さんは、 samba (人気の SMB/CIFS 実装) に二つの問題を発見しました。 これらの問題は以下の通りです:

  • smbd で用いられている、SMB/CIFS パケットフラグメントを 再構成するコードにバッファオーバーフローがあります。 smbd は root 権限で動くため、攻撃者はこれを悪用して、 smbd を動かしているマシンで root 権限を奪取することができる 可能性があります。
  • reg ファイルに書き込みを行うコードには chown 時の競合関係があり、 ローカルのユーザがシステムファイルを上書きできる可能性があります。

これらの問題は、上流のバージョン 2.2.8、Debian GNU/Linux 3.0/woody ではバージョン 2.2.3a-12.1 で修正されています。

修正:

Debian GNU/Linux 3.0 (woody)
