java-1.6.0-openjdk security update (RHSA-2013-0246)

Original Release Date: April 2, 2013
Last Revised: October 15, 2013
Number: ASA-2013-175
Risk Level: Medium
Advisory Version: 3.0
Advisory Status: Final

1. Overview:

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

Multiple improper permission check issues were discovered in the AWT, CORBA, JMX, and Libraries components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2013-0442, CVE-2013-0445, CVE-2013-0441, CVE-2013-1475, CVE-2013-1476, CVE-2013-0429, CVE-2013-0450, CVE-2013-0425, CVE-2013-0426 and CVE-2013-0428 to these issues. .

Multiple flaws were found in the way image parsers in the 2D and AWT components handled image raster parameters. A specially-crafted image could cause Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with the virtual machine privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2013-1478 and CVE-2013-1480 to these issues.

A flaw was found in the AWT component's clipboard handling code. An untrusted Java application or applet could use this flaw to access clipboard data, bypassing Java sandbox restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0432 to this issue.

The default Java security properties configuration did not restrict access to certain com.sun.xml.internal packages. An untrusted Java application or applet could use this flaw to access information, bypassing certain Java sandbox restrictions. This update lists the whole package as restricted. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0435 to this issue.

Multiple improper permission check issues were discovered in the Libraries, Networking, and JAXP components. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2013-0427, CVE-2013-0433 and CVE-2013-0434 to these issues.

It was discovered that the RMI component's CGIHandler class used user inputs in error messages without any sanitization. An attacker could use this flaw to perform a cross-site scripting (XSS) attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0424 to this issue.

It was discovered that the SSL/TLS implementation in the JSSE component did not properly enforce handshake message ordering, allowing an unlimited number of handshake restarts. A remote attacker could use this flaw to make an SSL/TLS server using JSSE consume an excessive amount of CPU by continuously restarting the handshake. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0440 to this issue.

It was discovered that the JSSE component did not properly validate Diffie-Hellman public keys. An SSL/TLS client could possibly use this flaw to perform a small subgroup attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0443 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by Red Hat:

2. Avaya System Products using a modified version of RHEL5 with affected packages installed:

Product: Affected Version(s): Risk Level: Actions:
Avaya Aura® Conferencing Standard Edition 6.0.x Medium See recommended actions and mitigating factors table below. This advisory will not be addressed as no further releases are planned. It is recommended that customers migrate to one of Avaya's conferencing solutions including Avaya Aura® Conferencing 7.0 or later.
Avaya Aura® System Platform 1.x, 6.0.x thru 6.3 Medium Upgrade to 6.3.1 or later.
Avaya Aura® Communication Manager Utility Services 6.0.x thru 6.2.x Medium Upgrade to 6.3 or later.

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-2013-0424
CVE-2013-0425
CVE-2013-0426
CVE-2013-0427
CVE-2013-0428
CVE-2013-0429
CVE-2013-0432
CVE-2013-0433
CVE-2013-0434
CVE-2013-0435
CVE-2013-0441
CVE-2013-0442
CVE-2013-0443
CVE-2013-0445
CVE-2013-0450
CVE-2013-1475
CVE-2013-1476
CVE-2013-1478
CVE-2013-1480
These are rated a low for all products as untrusted Java applications are not allowed to execute by default or would require local user access and would not provide additional capability.
CVE-2013-0440
This is rated a medium for all products due to the Denial of Service possibility.

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.
