Code Execution Vulnerability

https://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
applications.

Java runs on more than 850 million personal computers worldwide, and

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

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

The vulnerability is caused by an integer truncation error in the
Color Management Module (CMM) when processing a malformed "bfd" 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


IV. Binary Analysis & Exploits/PoCs
---------------------------------------

In-depth binary analysis of the vulnerability and a proof-of-concept code
