Synopsis

The remote host has an application that is affected by multiple denial of service vulnerabilities.

Description

The version of Apache Subversion Server installed on the remote host is prior to 1.6.21 or 1.7.x prior to 1.7.9. It is, therefore, affected by multiple denial of service (DoS) vulnerabilities in the 'mod_dav_svn' Apache HTTPD server module :

- A flaw exists in 'mod_dav_svn' that is triggered when handling node properties. (CVE-2013-1845)

- A NULL pointer dereference exists in the 'mod_dav_svn' module, triggered during the handling of a crafted Log REPORT request, URL lock request, LOCK request against non-existent URL, or URL PROPFIND request.
(CVE-2013-1846, CVE-2013-1847, CVE-2013-1849)

- A NULL pointer dereference exists in the 'mod_dav_svn' module, triggered during the handling of a crafted Log REPORT request. This flaw reportedly affects Apache Subversion 1.7.x only. (CVE-2013-1884)

Solution

Upgrade to Apache Subversion Server 1.6.21 / 1.7.9 or later.
