RHEL 4 / 5 : subversion (RHSA-2009:1203)

High Nessus Plugin ID 40541


The remote Red Hat host is missing one or more security updates.


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.


Update the affected packages.
