Abstract

These vulnerabilities are only applicable to Java deployments where untrusted code may be executed under a security manager (e.g. Java applets running in a web browser).

VULNERABILITY DETAILS:

CVE IDs: CVE-2012-4820, CVE-2012-4821, CVE-2012-4822, CVE-2012-4823

DESCRIPTION:
There are a number of vulnerabilities in the IBM JAVA SDK that affect various components (ORB, XML and JMX). The vulnerabilities allow code running under a security manager to escalate its privileges by modifying or removing the security manager. Some of the issues need to be combined in sequence to achieve an exploit.

The vulnerabilities could occur when the IBM JRE is installed as the system JRE, such that it may be used to execute untrusted Java applets or Web Start applications in a browser.
