Security Advisory Description

The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request. (CVE-2013-6438)

Impact

A remote user can cause a denial-of-service (DoS) attack using a crafted DAV WRITE request.
