"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.

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."
