-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Oracle Java Runtime running on OSX or
Linux. This vulnerability does not affect java running on Windows. 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 'crdi' tag it is
possible to specify a value that can cause an integer to wrap. This
integer is then used to specify the size of a heap allocation. By
providing a specially crafted tag value an attacker can cause memory
corruption that can lead to remote code being executed under to user
running the browser.
