CVE-2018-1517

Description

A flaw in the IBM Java Runtime Environment's java.math.BigInteger and
java.math.BigDecimal APIs leads to a hang when a particular class of values is
parsed from String data. This can be exploited to inflict a DoS attack.

The implementation has been improved to handle these values in a performant
manner.
