Vulnerability Details
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 https://exchange.xforce.ibmcloud.com/vulnerabilities/
157513 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2018-12547
DESCRIPTION: Eclipse OpenJ9 is vulnerable to a buffer overflow, caused by
improper bounds checking by the jio_snprintf() and jio_vsnprintf() functions.
By sending an overly long argument, a remote attacker could overflow a buffer
and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 9.8
