-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of java. User interaction is required to
exploit this vulnerability in that the target must visit a malicious
page.

The specific flaw exists within the way Java handles color profiles.
When parsing a color profile containing a invalid MultiLanguage 'mluc'
tag it is possible to cause an integer to wrap during an arithmetic
operation. This new value is used to allocate memory on the heap. A
remote attacker can abuse the faulty code to execute code under the
context of the user running the browser.
