This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
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.

Description
Missing incrementation of recursion depth counter were found in the xmlParserEntityCheck() and xmlParseAttValueComplex() functions used for parsing XML data. An attacker could launch a Denial of Service attack by passing specially crafted XML data to an application, forcing it to crash due to stack exhaustion.
