java-1.7.0-openjdk security update (RHSA-2015-0807)

Original Release Date: April 27, 2015
Last Revised: October 16, 2015
Number: ASA-2015-169
Risk Level: Low
Advisory Version: 2.0
Advisory Status: Final

1. Overview:

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit.

An off-by-one flaw, leading to a buffer overflow, was found in the font parsing code in the 2D component in OpenJDK. A specially crafted font file could possibly cause the Java Virtual Machine to execute arbitrary code, allowing an untrusted Java application or applet to bypass Java sandbox restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0469 to this issue.

A flaw was found in the way the Hotspot component in OpenJDK handled phantom references. An untrusted Java application or applet could use this flaw to corrupt the Java Virtual Machine memory and, possibly, execute arbitrary code, bypassing Java sandbox restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0460 to this issue.

A flaw was found in the way the JSSE component in OpenJDK parsed X.509 certificate options. A specially crafted certificate could cause JSSE to raise an exception, possibly causing an application using JSSE to exit unexpectedly. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0488 to this issue.

A flaw was discovered in the Beans component in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0477 to this issue.

A directory traversal flaw was found in the way the jar tool extracted JAR archive files. A specially crafted JAR archive could cause jar to overwrite arbitrary files writable by the user running jar when the archive was extracted. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-1080 and CVE-2015-0480 to these issues.

It was found that the RSA implementation in the JCE component in OpenJDK did not follow recommended practices for implementing RSA signatures. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0478 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 IP Office Application Server 8.x Low See recommended actions and Mitigating Factors table below. This advisory will not be addressed as no further service packs or security updates are planned. It is recommended that customers upgrade to 9.1 or later to continue to receive software update support.
Avaya Aura® System Platform 6.3 thru 6.3.6 Low Upgrade to 6.3.7 or later.

Recommended Actions for System Products:
Avaya strongly recommends following 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 the System Product operating system or application should not be modified 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-2005-1080
CVE-2015-0480
These are a Low risk because extraction of untrusted JAR archive files requires non-standard direct user interaction.
CVE-2015-0460
CVE-2015-0477
These are a Low risk because execution of untrusted Java applications or applets requires non-standard direct user interaction.
CVE-2015-0469 This is a Low risk because parsing of a specially crafted font file requires non-standard direct user interaction.
CVE-2015-0478 This is a Low risk because the JCE component is not used to implement RSA signatures by default.
CVE-2015-0488 This is a Low risk because verification and use of untrusted certificates requires non-standard direct user interaction.

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 Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the AES application.
Avaya IQ Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the Avaya IQ application.
CVLAN Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the CVLAN application.
Avaya Integrated Management Suite (IMS) Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the IMS application.
Avaya Aura® Presence Services Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the PS application.

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