DSA-1542-1 libcairo -- 整数オーバフロー

報告日時:
2008-04-09
影響を受けるパッケージ:
libcairo
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-2007-5503.
詳細:

Peter Valchev (Google Security) さんにより、様々なアプリケーションで利用 されているグラフィックレンダリングライブラリ Cairo に複数の整数オーバフ ローが発見されました。アプリケーションが悪意を持って細工された PNG 画像 を cairo を用いてレンダリングすることにより、任意のコードの実行の可能性 があります。

安定版 (stable) 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 1.2.4-4.1+etch1 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、これらの問題はバー ジョン 1.4.10-1.1 で修正されています。

直ぐに libcairo パッケージをアップグレードすることを勧めます。
