Multiple vulnerabilities in IBM Java SDK affect IBM Security Privileged
Identity Manager
Security Bulletin
Summary
There are multiple vulnerabilities in IBM SDK Java Technology Edition used by
IBM Security Privileged Identity Manager (ISPIM).
Vulnerability Details
CVEID: CVE-2019-11775
DESCRIPTION: All builds of Eclipse OpenJ9 prior to 0.15 contain a bug where the
loop versioner may fail to privatize a value that is pulled out of the loop by
versioning - for example if there is a condition that is moved out of the loop
that reads a field we may not privatize the value of that field in the modified
copy of the loop allowing the test to see one value of the field and
subsequently the loop to see a modified field value without retesting the
condition moved out of the loop. This can lead to a variety of different issues
but read out of array bounds is one major consequence of these problems.
CVSS Base score: 8.4

164479 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2019-11772
DESCRIPTION: In Eclipse OpenJ9 prior to 0.15, the String.getBytes(int, int,
byte[], int) method does not verify that the provided byte array is non-null
nor that the provided index is in bounds when compiled by the JIT. This allows
arbitrary writes to any 32-bit address or beyond the end of a byte array within
Java code run under a SecurityManager.

CVEID: CVE-2019-2766
DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded component of Oracle
Java SE (subcomponent: Networking). Supported versions that are affected are
Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to
exploit vulnerability allows unauthenticated attacker with network access via
multiple protocols to compromise Java SE, Java SE Embedded. 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, Java SE Embedded 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 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.0
/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).
CVSS Base score: 3.1

CVEID: CVE-2019-2786
DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded component of Oracle
Java SE (subcomponent: Security). Supported versions that are affected are Java
SE: 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to exploit
vulnerability allows unauthenticated attacker with network access via multiple
protocols to compromise Java SE, Java SE Embedded. Successful attacks require
human interaction from a person other than the attacker and while the
vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact
additional products. Successful attacks of this vulnerability can result in
unauthorized read access to a subset of Java SE, Java SE Embedded 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

CVEID: CVE-2019-2816
DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded component of Oracle
Java SE (subcomponent: Networking). Supported versions that are affected are
Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Difficult to
exploit vulnerability allows unauthenticated attacker with network access via
multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks
of this vulnerability can result in unauthorized update, insert or delete
access to some of Java SE, Java SE Embedded accessible data as well as
unauthorized read access to a subset of Java SE, Java SE Embedded 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 4.8
(Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N)
CVEID: CVE-2019-2762
DESCRIPTION: Vulnerability in the Java SE, Java SE Embedded component of Oracle
Java SE (subcomponent: Utilities). Supported versions that are affected are
Java SE: 7u221, 8u212, 11.0.3 and 12.0.1; Java SE Embedded: 8u211. Easily
exploitable vulnerability allows unauthenticated attacker with network access
via multiple protocols to compromise Java SE, Java SE Embedded. Successful
attacks of this vulnerability can result in unauthorized ability to cause a
partial denial of service (partial DOS) of Java SE, Java SE Embedded. 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

by using APIs in the specified Component, e.g., through a web service which
