A flaw was found in the hivex library in versions before 1.3.20. It is
caused due to a lack of bounds check within the hivex_open function. An
attacker could input a specially crafted Windows Registry (hive) file which
would cause hivex to read memory beyond its normal bounds or cause the
program to crash. The highest threat from this vulnerability is to system
availability.
