The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security fixes:
* A NULL pointer dereference flaw was found in the Linux kernel NFSv4 implementation. Several of the NFSv4 file locking functions failed to check whether a file had been opened on the server before performing locking operations on it. A local, unprivileged user on a system with an NFSv4 share mounted could possibly use this flaw to cause a kernel panic (denial of service) or escalate their privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3726 to this issue.
* A flaw was found in the sctp_process_unk_param() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially-crafted SCTP packet to an SCTP listening port on a target system, causing a kernel panic (denial of service). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1173 to this issue.
* A race condition between finding a keyring by name and destroying a freed keyring was found in the Linux kernel key management facility. A local, unprivileged user could use this flaw to cause a kernel panic (denial of service) or escalate their privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1437 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's
product and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as a product
update is available or the recommended action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period.
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.
