The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issue:
A flaw in the xfrm6_tunnel_rcv() function in the Linux kernel's IPv6 implementation could lead to a use-after-free or double free flaw in tunnel6_rcv(). A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the xfrm6_tunnel kernel module loaded, causing it to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1583 to this issue.

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.
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-2012-1583 |
This is no risk to Communication Manager 5.2.x, Presence Services, Session Manager, SIP Enablement Services and Voice Portal as ipv6 is not enabled or configured by default and it's use is not supported. This is a low risk for all other products as the xfrm6_tunnel kernel module 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.
