(RHSA-2011:0328) 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 certain requests to lock working copy paths in a repository. A
remote attacker could issue a lock request that could cause the httpd
process serving the request to crash. (CVE-2011-0715)

Red Hat would like to thank Hyrum Wright of the Apache Subversion project
for reporting this issue. Upstream acknowledges Philip Martin, WANdisco,
Inc. 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.
