Detailsinfo

A vulnerability has been found in Apache Subversion (Versioning Software) and classified as critical. Affected by this vulnerability is the function get_resource of the file mod_dav_svn/repos.c of the component mod_dav_svn/repos.c. The manipulation of the argument non-GET HTTP Requests with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect availability. The summary by CVE is:

The get_resource function in repos.c in the mod_dav_svn module in Apache Subversion before 1.7.15 and 1.8.x before 1.8.6, when SVNListParentPath is enabled, allows remote attackers to cause a denial of service (crash) via vectors related to the server root and request methods other than GET, as demonstrated by the "svn ls http://svn.example.com" command.

The weakness was shared 01/10/2014 as Revision 1557320 as confirmed advisory (Website). It is possible to read the advisory at svn.apache.org.
