Pour plus d'information:

Plusieurs problèmes ont été découverts dans Apache 2, le serveur web de prochaine génération, évolutif et souple. Le projet « Common Vulnerabilities and Exposures » a identifié les problèmes suivants :

CAN-2005-1268
Marc Stern a découvert une erreur due à un décalage d'entier dans la fonction de retour qui vérifie la liste de révocation des certificats (Certificate Revocation List (CRL)) dans mod_ssl. Lorsqu'Apache était configuré pour utiliser un « CRL », cela pouvait être utilisé pour provoquer un déni de service.
CAN-2005-2088
Une vulnérabilité a été découverte dans le serveur web Apache. Lorsqu'Apache agissait en mandataire (« proxy ») HTTP, les attaquants distants pouvaient polluer le cache web, contourner les protections par pare-feu web applicatif et conduire des attaques de scripts sur les éléments dynamiques (cross-site scripting), empêchant Apache de correctement gérer et transmettre la requête.
CAN-2005-2700
Un problème a été découvert dans mod_ssl, fournissant du chiffrage fort (gestion de HTTPS), qui permettait aux attaquants distants de contourner les restrictions d'accès.
CAN-2005-2728
Le filtre décodant l'option « Range » dans Apache 2.0 permettait aux attaquants distants de provoquer un déni de service en utilisant un en-tête HTTP avec un champ « Range » de taille conséquente.

L'ancienne distribution stable (Woody) ne contient pas de paquet Apache 2.

Pour l'actuelle distribution stable (Sarge), ces problèmes ont été corrigés dans la version 2.0.54-5.

Pour la distribution instable (Sid), ces problèmes ont été corrigés dans la version 2.0.54-5.

Nous vous recommandons de mettre à jour vos paquets apache2.

Corrigé dans:

Debian GNU/Linux 3.1 (sarge)
