Vulnerability Information

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated java-1.6.0-openjdk packages that fix several security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit.

Multiple flaws were discovered in the CORBA (Common Object Request Broker Architecture) implementation in Java. A malicious Java application or applet could use these flaws to bypass Java sandbox restrictions or modify immutable object data. (CVE-2012-1711, CVE-2012-1719)

It was discovered that the SynthLookAndFeel class from Swing did not properly prevent access to certain UI elements from outside the current application context. A malicious Java application or applet could use this flaw to crash the Java Virtual Machine, or bypass Java sandbox restrictions. (CVE-2012-1716)

Multiple flaws were discovered in the font manager's layout lookup implementation. A specially crafted font file could cause the Java Virtual Machine to crash or, possibly, execute arbitrary code with the privileges of the user running the virtual machine. (CVE-2012-1713)

Multiple flaws were found in the way the Java HotSpot Virtual Machine verified the bytecode of the class file to be executed. A specially crafted Java application or applet could use these flaws to crash the Java Virtual Machine, or bypass Java sandbox restrictions. (CVE-2012-1723, CVE-2012-1725)

It was discovered that the Java XML parser did not properly handle certain XML documents. An attacker able to make a Java application parse a specially crafted XML file could use this flaw to make the XML parser enter an infinite loop. (CVE-2012-1724)

It was discovered that the Java security classes did not properly handle Certificate Revocation Lists (CRL). CRL containing entries with duplicate certificate serial numbers could have been ignored. (CVE-2012-1718)

It was discovered that various classes of the Java Runtime library could create temporary files with insecure permissions. A local attacker could use this flaw to gain access to the content of such temporary files. (CVE-2012-1717)

Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.

This erratum also upgrades the OpenJDK package to IcedTea6 1.11.3. Refer to the NEWS file, linked to in the References, for further information.

All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.

Solution

Update the affected packages.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB, GitHub, Core Impact)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the RHEL 6 : java-1.6.0-openjdk (RHSA-2012:0729) vulnerability:

Metasploit: exploit/multi/browser/java_verifier_field_access
[Java Applet Field Bytecode Verifier Cache Remote Code Execution]
Exploit-DB: exploits/java/remote/19717.rb
[EDB-19717: Java Applet - Field Bytecode Verifier Cache Remote Code Execution (Metasploit)]
GitHub: https://github.com/EthanNJC/CVE-2012-1723
[CVE-2012-1723: Proof of concept exploit for CVE-2012-1723]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.

How to Run

Here is how to run the RHEL 6 : java-1.6.0-openjdk (RHSA-2012:0729) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Red Hat Local Security Checks plugin family.
On the right side table select RHEL 6 : java-1.6.0-openjdk (RHSA-2012:0729) plugin ID 59489.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl redhat-RHSA-2012-0729.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2012-0729.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - redhat-RHSA-2012-0729.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state redhat-RHSA-2012-0729.nasl -t <IP/HOST>

Go back to menu.
