DSA-2122-1 glibc -- 入力のサニタイズ漏れ

報告日時:
2010-10-22
影響を受けるパッケージ:
glibc
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 600667.
Mitre の CVE 辞書: CVE-2010-3847, CVE-2010-3856.
詳細:

Ben Hawkes さんと Tavis Ormandy さんにより、GNU libc のダイナミックローダ が、細工された LD_AUDIT 環境変数を使った root 特権の取得を許すことが発見 されました。

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 2.7-18lenny6 で修正されています。

次期安定版 (squeeze) ディストリビューションでは、これらの問題はバージョン 2.11.2-6+squeeze1 の eglibc パッケージ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、この問題は近 く修正予定です。

直ぐに glibc/eglibc 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 5.0 (lenny)
