EUVDB-ID: #VU44142

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-17639

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

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.

Mitigation

Install update from vendor's website.
