There are multiple vulnerabilities in IBM Runtime Environment Java Versions 6
and 7used by IBM Process Designer. IBM Process Designer has addressed the
applicable CVEs.
Vulnerability Details
CVEID: CVE-2018-3139
DESCRIPTION: An unspecified vulnerability related to the Java SE Networking
component could allow an unauthenticated attacker to obtain sensitive
information resulting in a low confidentiality impact using unknown attack
vectors.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
151455 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N)
CVEID: CVE-2018-3180
DESCRIPTION: An unspecified vulnerability related to the Java SE JSSE component
could allow an unauthenticated attacker to cause low confidentiality impact,
low integrity impact, and low availability impact.
CVSS Base Score: 5.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
151497 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2018-11212
DESCRIPTION: libjpeg is vulnerable to a denial of service, caused by
divide-by-zero error in the alloc_sarray function in jmemmgr.c. By persuading a
victim to open a specially-crafted file, a remote attacker could exploit this
vulnerability to cause the application to crash.
CVSS Base Score: 3.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
143429 for the current score
CVSS Environmental Score*: Undefined

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