Summary
Nokogiri subject to DoS via libxml2 vulnerability
Details

The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 (as used in nokogiri before 1.6.7.1) does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660.
