CentOS Update for mod_dav_svn CESA-2015:1742 centos7

Published: 2015-09-09 04:27:33
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Detection Type:
Linux Distribution Package

Summary:
Check the version of mod_dav_svn

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
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. 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) Red Hat would like to thank the Apache Software Foundation for reporting these issues. Upstream acknowledges Evgeny Kotkov of VisualSVN as the original reporter of CVE-2015-0248 and CVE-2015-0251, and C. Michael Pilato of CollabNet as the original reporter of CVE-2015-3184 and CVE-2015-3187 flaws. All subversion users should upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues. After installing the updated Linux Distribution 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.

Affected Versions:
mod_dav_svn on CentOS 7

Recommendations:
Please install the updated Linux Distribution Packages.

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
