Important: subversion security update

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.

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

This update is available via Red Hat Network. Details on how to use
