initscripts security and bug fix update (RHSA-2012-0312)

Original Release Date: May 2, 2012
Last Revised: September 28, 2015
Number: ASA-2012-196
Risk Level: Low
Advisory Version: 6.0
Advisory Status: Final

1. Overview:

The initscripts package contains system scripts to boot your system, change runlevels, activate and deactivate most network interfaces, and shut the system down cleanly.

With the default IPsec (Internet Protocol Security) ifup script configuration, the racoon IKE key management daemon used aggressive IKE mode instead of main IKE mode. This resulted in the preshared key (PSK) hash being sent unencrypted, which could make it easier for an attacker able to sniff network traffic to obtain the plain text PSK from a transmitted hash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-1198 to this issue.

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

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-2008-1198
There is no risk for Application Enablement Services, Conferencing, Proactive Contact, Session Manager, System Platform, Utility Services, and Voice Portal because ipsec-tools is not installed by default, and so IPSec connections could not be established.
There is no risk for CS1000 because it uses a 3rd party IPSec implementation which is not vulnerable to this issue.
The risk is Low for Communication Manager, IP Office Application Server, IQ, Messaging, Presence Services and System Manager because IPSec is not used by default.
The risk is Low for AS5300 because the access complexity of the exploit is high, and IPSec is used only between servers on a local network.

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.
