CVEID: CVE-2018-12549
DESCRIPTION: Eclipse OpenJ9 could allow a remote attacker to execute arbitrary
code on the system, caused by the failure to omit a null check on the receiver
object of an Unsafe call when accelerating it. An attacker could exploit this
vulnerability to execute arbitrary code on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See
