CVE-2016-3705

Disclosure Date: May 17, 2016
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

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.
