The kernel packages contain the Linux kernel, the core of any Linux operating system.
Information leaks in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2012-6544, CVE-2012-6545, CVE-2013-3222, CVE-2013-3224, CVE-2013-3231 and CVE-2013-3235 to these issues.
An information leak was found in the Linux kernel's POSIX signals implementation. A local, unprivileged user could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0914 to this issue.
A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-1929 to this issue.

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.
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-2012-6544 CVE-2012-6545 CVE-2013-0914 CVE-2013-3222 CVE-2013-3224 CVE-2013-3231 CVE-2013-3235 |
The risk is rated Low for CM, CS1000, Conferencing, Conferencing Standard Edition, Meeting Exchange, Messaging, Proactive Contact, SES and Session Manager because all local users are privileged users. The risk is rated Medium for all other products because of the potential for an application crash and/or privilege escalation. |
| CVE-2013-1929 | The risk is rated None for all products because the affected Ethernet driver is not loaded by default. |
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.
