"Updated subversion packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.

Matt Lewis, of Google, reported multiple heap overflow flaws in
Subversion (server and client) when parsing binary deltas. A malicious
user with commit access to a server could use these flaws to cause a
heap overflow on that server. A malicious server could use these flaws
to cause a heap overflow on a client when it attempts to checkout or
update. These heap overflows can result in a crash or, possibly,
arbitrary code execution. (CVE-2009-2411)

All Subversion users should upgrade to these updated packages, which
contain a backported patch 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."
