New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

A NULL pointer dereference flaw was found in the way the mod_dav_svn module handled REPORT requests. A remote, unauthenticated attacker could use a specially crafted REPORT request to crash mod_dav_svn.
(CVE-2014-3580)

A NULL pointer dereference flaw was found in the way the mod_dav_svn module handled certain requests for URIs that trigger a lookup of a virtual transaction name. A remote, unauthenticated attacker could send a request for a virtual transaction name that does not exist, causing mod_dav_svn to crash. (CVE-2014-8108)

It was discovered that Subversion clients retrieved cached authentication credentials using the MD5 hash of the server realm string without also checking the server's URL. A malicious server able to provide a realm that triggers an MD5 collision could possibly use this flaw to obtain the credentials for a different realm.
(CVE-2014-3528)

After installing the updated packages, for the update to take effect, you must restart the httpd daemon, if you are using mod_dav_svn, and the svnserve daemon, if you are serving Subversion repositories via the svn:// protocol.

Solution

Update the affected packages.
