Debian-specific: no
CVE Id         : CAN-2002-1363

Glenn Randers-Pehrson さんにより、PNG (Portable Network Graphics) フォー
マットの画像ファイルを読み書きするためのライブラリ libpng に問題が発見さ
れました。16bit 画像の処理時にループ開始オフセットの計算を誤っており、ロ
ーバッファの開始点を越えてバッファオーバランを起こす可能性があります。

現安定版 (stable) woody では、これは libpng のバージョン 1.0.12-3.woody.3
および libpng3 のバージョン 1.2.1-1.1.woody.3 で修正されています。

前安定版 (stable) potato では、これはバージョン 1.0.5-1.1 で修正されてい
ます。potato にはこれ以外の libpng パッケージは収録されていません。

不安定版 (unstable) sid  では、これは libpng のバージョン 1.0.12-7 およ
び libpng3 のバージョン 1.2.5-8 で修正されています。

直ぐに libpng パッケージをアップグレードすることを勧めます。

wget url
	でファイルを取得できます。
dpkg -i file.deb
        で参照されたファイルをインストールできます。

apt-get パッケージマネージャを使っているなら、以下記載の sources.list
を用いて、次のコマンドを使ってください。

apt-get update
        これは内部データベースを更新します。
apt-get upgrade
        これで修正されたパッケージをインストールします。

本メールのフッタ記載の設定を自ホストの設定に加えることにより、自動更新を
行うこともできます。
