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.

Exploit prediction (EPSS)

5.10% probability of exploitation in the next 30 days, higher than 92% of all scored CVEs.
