Description

This security bulletin contains information about 1 security vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2013-1896)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

mod_dav.c in the Apache HTTP Server before 2.2.25 does not properly determine whether DAV is enabled for a URI, which allows remote attackers to cause a denial of service (segmentation fault) via a MERGE request in which the URI is configured for handling by the mod_dav_svn module, but a certain href attribute in XML data refers to a non-DAV URI.


Remediation
