Description

iDefense Security Advisory 03.30.10 http://labs.idefense.com/intelligence/vulnerabilities/ Mar 30, 2010

I. BACKGROUND

The Java Runtime Environment (JRE) is the Sun Microsystems implementation of the Java run-time. For more information, visit the link shown below.

http://www.sun.com/java/

II. DESCRIPTION

Remote exploitation of a buffer overflow vulnerability in Oracle Corp.'s (formerly Sun Microsystems Inc.) Java Runtime Environment (JRE) could allow an attacker to execute arbitrary code with the privileges of the current user. The JRE is a platform that supports the execution of programs that are developed using the Java programming language. It is available for multiple platforms, including Windows, Linux and MacOS. The JRE platform also supports Java Applets, which can be loaded from Web pages. During the processing of an image file, user-controlled data is trusted and can result in an undersized allocation of a heap buffer. A copy operation into the heap buffer can lead to a heap overflow condition within the JRE. This condition may allow a remote attacker to subvert execution control and execute arbitrary code.

III. ANALYSIS

Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the user viewing the Web page. To exploit this vulnerability, a targeted user must visit a website and load a malicious Java Applet created by an attacker. An attacker typically accomplishes this via social engineering or injecting content into a compromised, trusted site.

IV. DETECTION

iDefense has confirmed the existence of this vulnerability in version 1.6.0u17 of Java Runtime Environment. iDefense tested the exploitation of this vulnerability on Windows XP SP3 and Windows XP SP2.
