The kernel packages contain the Linux kernel, the core of any Linux operating system.
These updated packages fix the following security issues:
* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially-crafted packet that would cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1385 to this issue.
* the Linux kernel Network File System daemon (nfsd) implementation did not drop the CAP_MKNOD capability when handling requests from local, unprivileged users. This flaw could possibly lead to an information leak or privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1072 to this issue.
* the NFSv4 client was missing a file permission check for the execute bit in some situations. This could allow local, unprivileged users to run non-executable files on NFSv4 mounted file systems. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1630 to this issue.
* a missing check was found in the hypervisor_callback() function in the Linux kernel provided by the kernel-xen package. This could cause a denial of service of a 32-bit guest if an application running in that guest accesses a certain memory location in the kernel. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1758 to this issue.
* a flaw was found in the AGPGART driver. The agp_generic_alloc_page() and agp_generic_alloc_pages() functions did not zero out the memory pages they allocate, which may later be available to user-space processes. This flaw could possibly lead to an information leak. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1192 to this issue.

Recommended Actions:
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. 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.
