Debian Security Advisory DSA-1441-1                  security@debian.org
http://www.debian.org/security/                          Thijs Kinkhorst
December 28, 2007                     http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package        : peercast
Vulnerability  : バッファオーバフロー
Problem-Type   : リモート
Debian-specific: いいえ
CVE ID         : CVE-2007-6454
Debian Bug     : 457300

Luigi Auriemma さんにより、P2P オーディオおよびヴィデオストリーミングサ
ーバ Peercast の HTTP サーバコードにヒープオーバフローがあり、リモートの
攻撃者による長大な SOURCE リクエストを用いたサービス拒否攻撃が可能で、更
に任意コード実行の恐れがある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 (etch) では、この問題はバージョン
0.1217.toots.20060314-1etch0 で修正されています。

旧安定版 (sarge) には peercast パッケージは収録されていません。

不安定版 (unstable) ディストリビューション (sid) では、この問題はバージョ
ン 0.1218+svn20071220+2 で修正されています。

直ぐに peercast パッケージをアップグレードすることを勧めます。


アップグレード手順
------------------

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用いている場合には、本メールのフッタ記載の
行を sources.list に加えて、

apt-get update
        を実行して内部データベースを更新し、
apt-get upgrade
        によって修正されたパッケージをインストールしてください。

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。



Debian 4.0 (stable)
- -------------------

安定版の更新は、alpha, amd64, arm, hppa, i386, ia64, mips, mipsel,
powerpc, s390 および sparc の各アーキテクチャで提供されています。
