Vulnerability Details

CVEID: CVE-2018-1656 DESCRIPTION: The IBM Java Runtime Environment’s Diagnostic Tooling Framework for Java (DTFJ) does not protect against path traversal attacks when extracting compressed dump files.
CVSS Base Score: 7.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/144882 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:N)

CVEID:CVE-2018-12539
**DESCRIPTION:*Eclipse OpenJ9 could allow a local attacker to gain elevated privileges on the system, caused by the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. An attacker could exploit this vulnerability to execute untrusted native code and gain elevated privileges on the system.
