denial-of-sevice attack (CVE-2016-3627).
libxml2 limits the number of recursions an XML document can contain so to
protect against the 'Billion Laughs' denial-of-service attack.
Unfortunately, the underlying counter was not incremented properly in all
necessary locations. Therefore, specially crafted XML documents could
exhaust all available stack space and crash the XML parser without running
into the recursion limit (CVE-2016-3705).");
