CentOS Update for mod_dav_svn CESA-2013:0737 centos6

Published: 2013-04-15 04:43:14
CVE Author: NIST National Vulnerability Database

Affected Versions:
mod_dav_svn on CentOS 6

Please install the updated Linux Distribution Packages.

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. A NULL pointer dereference flaw was found in the way the mod_dav_svn module handled PROPFIND requests on activity URLs. A remote attacker could use this flaw to cause the httpd process serving the request to crash. (CVE-2013-1849) A flaw was found in the way the mod_dav_svn module handled large numbers of properties (such as those set with the 'svn propset' command). A malicious, remote user could use this flaw to cause the httpd process serving the request to consume an excessive amount of system memory. (CVE-2013-1845) Two NULL pointer dereference flaws were found in the way the mod_dav_svn module handled LOCK requests on certain types of URLs. A malicious, remote user could use these flaws to cause the httpd process serving the request to crash. (CVE-2013-1846, CVE-2013-1847) Note: The CVE-2013-1849, CVE-2013-1846, and CVE-2013-1847 issues only caused a temporary denial of service, as the Apache HTTP Server started a new process to replace the crashed child process. When using prefork MPM, the crash only affected the attacker. When using worker (threaded) MPM, the connections of other users may have been interrupted. Red Hat would like to thank the Apache Subversion project for reporting these issues. Upstream acknowledges Alexander Klink as the original reporter of CVE-2013-1845, Ben Reser as the original reporter of CVE-2013-1846, and Philip Martin and Ben Reser as the original reporters of CVE-2013-1847. 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, you must restart the httpd daemon, if you are using mod_dav_svn, for the update to take effect.

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".
