CVE-2016-3705

UnknownEPSS 5.10%

Last modified

CVE-2016-3705 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.10% chance of exploitation in the next 30 days.
