Security Bulletin
Summary
IBM Java Runtime ais shipped with Tivoli Federated Identity Manager.
Information about security vulnerabilities affecting IBM Java Runtime
have been published in a security bulletin.
Vulnerability Details
CVEID: CVE-2018-12549
DESCRIPTION: In Eclipse OpenJ9 version 0.11.0, the OpenJ9 JIT compiler
may incorrectly omit a null check on the receiver object of an Unsafe
call when accelerating it.
CVSS Base score: 9.8
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/157513 for the
current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2019-2426
DESCRIPTION: Vulnerability in the Java SE component of Oracle Java SE
(subcomponent: Networking). Supported versions that are affected are
Java SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. Difficult to
exploit vulnerability allows unauthenticated attacker with network
access via multiple protocols to compromise Java SE. Successful attacks
of this vulnerability can result in unauthorized read access to a subset
of Java SE accessible data. Note: This vulnerability applies to Java
deployments, typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets (in Java SE 8), that load and run
untrusted code (e.g., code that comes from the internet) and rely on the
Java sandbox for security. This vulnerability can also be exploited by
using APIs in the specified Component, e.g., through a web service which
supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Confidentiality
impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).
CVSS Base score: 3.7
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/155744 for the
current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2019-2449
DESCRIPTION: Vulnerability in the Java SE component of Oracle Java SE
(subcomponent: Deployment). The supported version that is affected is
Java SE: 8u192. Difficult to exploit vulnerability allows
unauthenticated attacker with network access via multiple protocols to
compromise Java SE. Successful attacks require human interaction from a
person other than the attacker. Successful attacks of this vulnerability
can result in unauthorized ability to cause a partial denial of service
(partial DOS) of Java SE. Note: This vulnerability applies to Java
deployments, typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets (in Java SE 8), that load and run
untrusted code (e.g., code that comes from the internet) and rely on the
Java sandbox for security. This vulnerability does not apply to Java
deployments, typically in servers, that load and run only trusted code
(e.g., code installed by an administrator). CVSS 3.0 Base Score 3.1
(Availability impacts). CVSS Vector:
(CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L).
CVSS Base score: 3.1
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/155766 for the
current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L)
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. IBM X-Force ID: 152081.
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: In Eclipse OpenJ9, prior to the 0.12.0 release, the
jio_snprintf() and jio_vsnprintf() native methods ignored the length
parameter. This affects existing APIs that called the functions to
exceed the allocated buffer. This functions were not directly callable
by non-native user code.
CVSS Base score: 9.8
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/157512 for the
current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2018-11212
DESCRIPTION: An issue was discovered in libjpeg 9a. The alloc_sarray
function in jmemmgr.c allows remote attackers to cause a denial of
service (divide-by-zero error) via a crafted file.
CVSS Base score: 3.3
CVSS Temporal Score: See:
https://exchange.xforce.ibmcloud.com/vulnerabilities/143429 for the
current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2019-2422
DESCRIPTION: Vulnerability in the Java SE component of Oracle Java SE
(subcomponent: Libraries). Supported versions that are affected are Java
SE: 7u201, 8u192 and 11.0.1; Java SE Embedded: 8u191. Difficult to
exploit vulnerability allows unauthenticated attacker with network
access via multiple protocols to compromise Java SE. Successful attacks
require human interaction from a person other than the attacker.
Successful attacks of this vulnerability can result in unauthorized read
access to a subset of Java SE accessible data. Note: This vulnerability
applies to Java deployments, typically in clients running sandboxed Java

and rely on the Java sandbox for security. This vulnerability does not
