Overflow Code Execution Vulnerability

http://www.vupen.com/english/research.php


I. BACKGROUND
---------------------

"Java is a programming language and computing platform released by Sun
Microsystems (now Oracle). It is the underlying technology that powers
state-of-the-art programs including utilities, games, and business

II. DESCRIPTION
---------------------

VUPEN Vulnerability Research Team discovered a critical vulnerability
in Oracle Java.

The vulnerability is caused by an integer overflow error in the Color
Management Module (CMM) when processing a malformed "clrt" tag within
an ICC profile, which could be exploited by attackers to execute arbitrary
code by tricking a user into visiting a specially crafted web page.

CVSS Score: 10 (AV:N/AC:L/Au:N/C:C/I:C/A:C)


III. AFFECTED PRODUCTS
---------------------------

Oracle Java JDK and JRE 6 Update 25 and prior
