(RHSA-2011:0861) Moderate: subversion security update

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.
