CVE-2016-3705
Libxml2 XML Entity Reference Recursion Déjà Vu Denial of Service Vulnerability
Description
The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references.
