Synopsis

The remote Red Hat host is missing a security update for subversion.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0327 advisory.

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.

This update also fixes the following bug:

* A regression was found in the handling of repositories which do not have a db/fsfs.conf file. The svnadmin hotcopy command would fail when trying to produce a copy of such a repository. This command has been fixed to ignore the absence of the fsfs.conf file. The svnadmin hotcopy command will now succeed for this type of repository. (BZ#681522)

All Subversion users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, you must restart the httpd daemon, if you are using mod_dav_svn, for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL subversion package based on the guidance in RHSA-2011:0327.
