java-1.6.0-openjdk security update (RHSA-2012-0729)

Original Release Date: June 20, 2012
Last Revised: January 15, 2013
Number: ASA-2012-258
Risk Level: Low
Advisory Version: 2.0
Advisory Status: Final

1. Overview:

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2012-1711 and CVE-2012-1719 to these issues.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1716 to this issue.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1713 to this issue.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2012-1723 and CVE-2012-1725 to these issues.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1724 to this issue.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1718 to this issue.

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1717 to this issue.

2. Avaya System Products using a modified version of RHEL6 with affected components/packages installed:

Product: Affected Version(s): Risk Level: Actions:
Avaya Aura® Experience Portal 6.0 including 6.0 SP1 Low Upgrade to Experience Portal 6.0 SP2 and Avaya Enterprise Linux for Experience Portal 6.0 SP2.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:

Vulnerability Mitigating Factors
CVE-2012-1711
CVE-2012-1713
CVE-2012-1716
CVE-2012-1719
CVE-2012-1723
CVE-2012-1724
CVE-2012-1725
These are a low risk as applications or applets could not be installed on the system without privileged account access.
CVE-2012-1717
CVE-2012-1718
These are a low risk as no critical system applications or processes would be affected.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.

Product: Actions:
Avaya Aura® Application Enablement Services 4.x/5.x Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the AES application.
CVLAN Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application.
Avaya Aura® Experience Portal Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the EP application.
Avaya Integrated Management Suite (IMS) Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IMS application.
Avaya Aura® Presence Services Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the PS application.
Avaya Secure Access Link Gateway Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the SAL Gateway application.
Avaya Aura® System Manager 1.0 Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the SMGR application.
Avaya Voice Portal Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the VP application.

Recommended Actions for Software-Only Products:
In the event that the affected package is installed, Avaya recommends that customers follow recommended actions supplied by Red Hat regarding their Enterprise Linux.
