Oracle Java SE 7 < Update 7 Multiple Vulnerabilities (Unix)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Unix host contains a programming platform that is affected
by multiple vulnerabilities.

Description :

The version of Oracle (formerly Sun) Java SE or Java for Business
installed on the remote host is earlier than 7 Update 7 and is,
therefore, potentially affected the following vulnerabilities :

- The 'getField' method in the 'sun.awt.SunToolkit class'
provided by the bundled SunToolkit can be used to
obtain any field of a class - even private fields.
This error can allow privilege escalation.
(CVE-2012-0547)

- Two unspecified remote code execution vulnerabilities
exist related to the
'com.sun.beans.finder.ConstructorFinder' and
'com.sun.beans.finder.FieldFinder' methods. No further
details have been provided. (CVE-2012-1682,
CVE-2012-3136)

- The 'setField' method provided by the bundled SunToolkit
can be used to execute a privileged operation and calls
'setAccessible(true)' on the returned field reference,
allowing an attacker to disable any 'final' or 'private'
directives and gain full control to run code in the Java
virtual machine. (CVE-2012-4681)

Note that at least one of these vulnerabilities is currently being
exploited in the wild.
