1) Type Confusion (CVE-ID: CVE-2019-17639)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error on Power platforms. A remote attacker can call the System.arraycopy method with a length longer than the length of the
source or destination array and cause the current method to return prematurely with an
undefined return value. As a result, a remote attacker can influence application flow and execute arbitrary code on the target system.
