New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

Synopsis

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

Description

An assertion failure flaw was found in the way the SVN server processed certain requests with dynamically evaluated revision numbers. A remote attacker could use this flaw to cause the SVN server (both svnserve and httpd with the mod_dav_svn module) to crash.
(CVE-2015-0248)

It was found that the mod_authz_svn module did not properly restrict anonymous access to Subversion repositories under certain configurations when used with Apache httpd 2.4.x. This could allow a user to anonymously access files in a Subversion repository, which should only be accessible to authenticated users. (CVE-2015-3184)

It was found that the mod_dav_svn module did not properly validate the svn:author property of certain requests. An attacker able to create new revisions could use this flaw to spoof the svn:author property.
(CVE-2015-0251)

It was found that when an SVN server (both svnserve and httpd with the mod_dav_svn module) searched the history of a file or a directory, it would disclose its location in the repository if that file or directory was not readable (for example, if it had been moved).
(CVE-2015-3187)

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.
