Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

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.
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)
Red Hat would like to thank the Apache Subversion project for reporting this issue. Upstream acknowledges Joe Schaefer of the Apache Software Foundation as the original reporter.
All Subversion users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, you must restart the httpd daemon, if you are using mod_dav_svn, for the update to take effect.
