xmlregexp in libxml2 before 2.15.4 has a NULL pointer dereference in xmlRegNewParserCtxt after a strdup failure, i.e., it does not calculate a string length after NULL checking.
Weakness
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
