RHEL 5 : subversion (RHSA-2011:0257)

medium Nessus Plugin ID 51994

Synopsis

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

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:0257 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.

 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.

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

Note that Nessus has not tested for these issues 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-2011:0257.
