libjpeg-turbo security update (RHSA-2013-1803)

Original Release Date: December 20, 2013
Last Revised: August 20, 2014
Number: ASA-2013-588
Risk Level: Low
Advisory Version: 2.0
Advisory Status: Final

1. Overview:

The libjpeg-turbo package contains a library of functions for manipulating JPEG images. It also contains simple client programs for accessing the libjpeg functions.

An uninitialized memory read issue was found in the way libjpeg-turbo decoded images with missing Start Of Scan (SOS) JPEG markers or Define Huffman Table (DHT) JPEG markers. A remote attacker could create a specially crafted JPEG image that, when decoded, could possibly lead to a disclosure of potentially sensitive information. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2013-6629 and CVE-2013-6630 to these issues.

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 RHEL6 with affected packages installed:

Product: Affected Version(s): Risk Level: Actions:
Avaya one-X® Client Enablement Services 6.2 thru 6.2 SP2 Low Upgrade to 6.2 SP3 or later.

Recommended Actions for System Products:
Avaya strongly recommends following the 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-2013-6629
CVE-2013-6630
These are a Low risk as exploitation would require either privileged account access to upload jpegs or the use of a browser, which are considered non-standard 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.
