Vulnerability from certfr_avis
Trois vulnérabilités ont été corrigées dans le module Subversion du serveur Apache. L'une d'entre-elles permet à un attaquant de réaliser un déni de service à distance.
Description
Plusieurs vulnérabilités ont été corrigées dans la version 1.6.17 du module Subversion mod_dav_svn pour le serveur Apache:
- un déréférencement de pointeur NULL permet à une personne malveillante d'arrêter le serveur de manière inopinée (CVE-2011-1752) ;
- dans certaines configurations du serveur, un attaquant peut réaliser un déni de service en utilisant des requêtes specialement conçues qui font entrer le programme dans une boucle infinie (CVE-2011-1783) ;
- dans certaines configurations du serveur, un utilisateur peut accéder au contenu des fichiers de manière illégitime (CVE-2011-1921).
Solution
Se référer au bulletin de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).
Module mod_dav_svn pour Apache HTTPD versions 1.5.0 à 1.6.16.

Summary
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is enabled, allows remote attackers to cause a denial of service (infinite loop and memory consumption) in opportunistic circumstances by requesting data.

Summary
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is disabled, does not properly enforce permissions for files that had been publicly readable in the past, which allows remote attackers to obtain sensitive information via a replay REPORT operation.
