TITLE

Oracle Java Arbitrary code execution vulnerability

DESCRIPTION

Multiple vulnerabilities in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 6 and earlier allow remote attackers to execute arbitrary code via a crafted applet that bypasses SecurityManager restrictions by (1) using com.sun.beans.finder.ClassFinder.findClass and leveraging an exception with the forName method to access restricted classes from arbitrary packages such as sun.awt.SunToolkit, then (2) using "reflection with a trusted immediate caller" to leverage the getField method to access and modify private fields, as exploited in the wild in August 2012 using Gondzz.class and Gondvv.class. An attacker can exploit the issue to execute arbitrary code in the context of the current process. Oracle Java SE is prone to a weakness in the Java Runtime Environment. The issue can be exploited over multiple protocols and affects the 'AWT' sub-component. Note: The flaw cannot be exploited directly but is dependent on any other security vulnerability that can be directly executed first. This issue affects the following supported versions: 7 Update 6 and before, 6 Update 34 and before. NOTE: this identifier was assigned by the Oracle CNA, but CVE is not intended to cover defense-in-depth issues that are only exposed by the presence of other vulnerabilities (CVE-2012-0547). The verification of md5 checksums and GPG signatures is performed automatically for you.

It was discovered that the Beans component in OpenJDK did not perform permission checks properly. An untrusted Java application or applet could use this flaw to use classes from restricted packages, allowing it to bypass Java sandbox restrictions. (CVE-2012-1682) A hardening fix was applied to the AWT component in OpenJDK, removing functionality from the restricted SunToolkit class that was used in combination with other flaws to bypass Java sandbox restrictions. (CVE-2012-0547) This erratum also upgrades the OpenJDK package to IcedTea6 1.10.9. Refer to the NEWS file, linked to in the References, for further information.

Overview A vulnerability in the way Java 7 restricts the permissions of Java applets could allow an attacker to execute arbitrary commands on a vulnerable system. An attacker could use social engineering techniques to entice a user to visit a link to a website hosting a malicious Java applet. An attacker could also compromise a legitimate web site and upload a malicious Java applet (a "drive-by download" attack). Any web browser using the Java 7 plug-in is affected. The Java Deployment Toolkit plug-in and Java Web Start can also be used as attack vectors. Reports indicate this vulnerability is being actively exploited, and exploit code is publicly available. Impact By convincing a user to load a malicious Java applet or Java Network Launching Protocol (JNLP) file, an attacker could execute arbitrary code on a vulnerable system with the privileges of the Java plug-in process. Solution Disable Java in web browsers This and previous Java vulnerabilities have been widely targeted by attackers, and new Java vulnerabilities are likely to be discovered. To defend against this and future Java vulnerabilities, disable Java in web browsers. Starting with Java 7 Update 10, it is possible to disable Java content in web browsers through the Java control panel applet. From Setting the Security Level of the Java Client: For installations where the highest level of security is required, it is possible to entirely prevent any Java apps (signed or unsigned) from running in a browser by de-selecting Enable Java content in the browser in the Java Control Panel under the Security tab. If you are unable to update to Java 7 Update 10 please see the solution section of Vulnerability Note VU#636312 for instructions on how to disable Java on a per browser basis.
