The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issues:
* A flaw was found in the Linux kernel's garbage collector for AF_UNIX sockets. A local, unprivileged user could use this flaw to trigger a denial of service (out-of-memory condition). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4249 to this issue.
* A flaw was found in the Linux kernel's networking subsystem. If the number of packets received exceeded the receiver's buffer limit, they were queued in a backlog, consuming memory, instead of being discarded. A remote attacker could abuse this flaw to cause a denial of service (out-of-memory condition). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4251 to this issue.
* A missing initialization flaw was found in the ethtool_get_regs() function in the Linux kernel's ethtool IOCTL handler. A local user who has the CAP_NET_ADMIN capability could use this flaw to cause an information leak. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4655 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:
|These are a low for all products as they would require privileged account access to exploit.|
||This is a medium for all products per the Security Vulnerability Classification Policy|
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.
