Description

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.
