Scientific Linux Security Update : subversion on SL5.x, SL6.x i386/x86_64

medium Nessus Plugin ID 61067

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Subversion (SVN) 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. (CVE-2011-1783)

A NULL pointer dereference flaw was found in the way the mod_dav_svn module processed requests submitted against the URL of a baselined resource. A malicious, remote user could use this flaw to cause the httpd process serving the request to crash. (CVE-2011-1752)

An information disclosure flaw was found in the way the mod_dav_svn module processed certain URLs when path-based access control for files and directories was enabled. A malicious, remote user could possibly use this flaw to access certain files in a repository that would otherwise not be accessible to them. Note: This vulnerability cannot be triggered if the SVNPathAuthz directive is set to 'short_circuit'.
(CVE-2011-1921)

All Subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, you must restart the httpd daemon, if you are using mod_dav_svn, for the update to take effect.

Solution

Update the affected packages.
