CVE-2011-1921

Status Candidate

Overview

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.

Red Hat Security Advisory 2011-0862-01
Posted Jun 9, 2011
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2011-0862-01 - Subversion is a concurrent version control system which enables one or more users to collaborate in developing and maintaining a hierarchy of files and directories while keeping a history of all changes. The mod_dav_svn module is used with the Apache HTTP Server to allow access to Subversion repositories via HTTP. An infinite loop flaw was found in the way the mod_dav_svn module processed certain data sets. If the SVNPathAuthz directive was set to "short_circuit", and path-based access control for files and directories was enabled, a malicious, remote user could use this flaw to cause the httpd process serving the request to consume an excessive amount of system memory. Various other issues were also addressed.

Mandriva Linux Security Advisory 2011-106
Posted Jun 4, 2011
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2011-106 - The mod_dav_svn Apache HTTPD server module will dereference a NULL pointer if asked to deliver baselined WebDAV resources which can lead to a denial of service. The mod_dav_svn Apache HTTPD server module may in certain scenarios enter a logic loop which does not exit and which allocates emory in each iteration, ultimately exhausting all the available emory on the server which can lead to a denial of service. The mod_dav_svn Apache HTTPD server module may leak to remote users the file contents of files configured to be unreadable by those users.
