CVEID:CVE-2019-2769
**DESCRIPTION:**An unspecified vulnerability in Oracle Java SE related to the Java SE, Java SE Embedded Utilities component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/163832 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2019-11771
**DESCRIPTION:**Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by the inclusion of unused RPATHS in AIX builds. An attacker could exploit this vulnerability to inject code and gain elevated privileges on the system.
CVSS Base score: 8.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/163989 for the current score.
