Vulnerability Details

   If you run your own Java code using the IBM Java Runtime delivered with
   this product, you should evaluate your code to determine whether
   additional Java vulnerabilities are applicable to your code. For a
   complete list of vulnerabilities, refer to the "IBM Java SDK Security
   Bulletin", located in the References section for more information.

   CVEID: CVE-2018-1890
   DESCRIPTION: IBM SDK, Java Technology Edition Version 8 on the AIX
   platform uses absolute RPATHs which may facilitate code injection and
   privilege elevation by local users.
   CVSS Base Score: 5.6
   CVSS Temporal Score:
   See https://exchange.xforce.ibmcloud.com/vulnerabilities/152081 for the
   current score

   CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L)

   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
