Security Bulletin: Vulnerability in IBM Java Runtime affects Rational 
Publishing Engine

Security Bulletin

Document information

More support for: Rational Publishing Engine

General Information

Software version: 1.3, 2.0.0, 2.0.1, 2.1.0, 2.1.1

Operating system(s): Linux

Software edition: All Editions

Reference #: 1996506

Modified date: 20 January 2017

Summary

There is a vulnerability in IBM Java Runtime Environment, Versions 6 and 7 
that are used by Rational Publishing Engine.

Vulnerability Details

CVEID: CVE-2016-5582

DESCRIPTION: A flaw in the Hotspot JIT compiler allows an attacker to disable
the security manager and execute arbitrary code.

CVSS Base Score: 9.6

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118069 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2016-5568

DESCRIPTION: A flaw in the AWT component allows an attacker to disable the 
security manager and execute arbitrary code.

CVSS Base Score: 9.6

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118068 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2016-5556

DESCRIPTION: A flaw in the font parser allows an attacker to corrupt the Java
heap using a maliciously crafted font file. In a server environment this could
be exploited by a remote attacker to cause a DoS by crashing the JVM. In a 
client deployment, or when running untrusted code under a security manager, 
the vulnerability potentially allows an attacker to disable the security 
manager and execute arbitrary code.

CVSS Base Score: 9.6

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118067 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2016-5573

DESCRIPTION: A flaw in the JDWP implementation potentially allows an attacker
to connect to a local JDWP port via javascript code or Flash documents in a 
malicious web page. This potentially allows remote execution of arbitrary 
code.

CVSS Base Score: 8.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118070 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2016-5597

DESCRIPTION: A flaw exists in the HttpURLConnection and HttpsURLConnection 
implementations when connecting via a proxy, which allows a man-in-the-middle
attacker to access proxy username and password information.

CVSS Base Score: 5.9

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118071 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2016-5554

DESCRIPTION: A flaw in the JMX component allows an attacker to bypass 
permission checks and access classes which should be restricted.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118072 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2016-5542

DESCRIPTION: If a JAR file is signed with old, weak hash algorithms, the class
files within it can be modified without the change being caught. This 
potentially enables attackers to inject malicious code into signed code from a
trusted third party.

CVSS Base Score: 3.1

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/118073 for the current 
score
