RHSA-2011:0257 - Moderate: subversion security update

Synopsis

Moderate: subversion security update

Type/Severity

Security Advisory Moderate

Topic

Updated subversion packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.

A server-side memory leak was found in the Subversion server. If a malicious, remote user performed "svn blame" or "svn log" operations on certain repository files, it could cause the Subversion server to consume a large amount of system memory. (CVE-2010-4644)

A NULL pointer dereference flaw was found in the way the mod_dav_svn module (for use with the Apache HTTP Server) processed certain requests. If a malicious, remote user issued a certain type of request to display a collection of Subversion repositories on a host that has the SVNListParentPath directive enabled, it could cause the httpd process serving the request to crash. Note that SVNListParentPath is not enabled by default. (CVE-2010-4539)

All Subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the Subversion server must be restarted for the update to take effect: restart httpd if you are using mod_dav_svn, or restart svnserve if it is used.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
