Updated kernel packages that fix multiple security issues, address several hundred bugs, and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 5. This is the sixth regular update.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A NULL pointer dereference flaw was found in the igb driver in the Linux kernel. If both the Single Root I/O Virtualization (SR-IOV) feature and promiscuous mode were enabled on an interface using igb, it could result in a denial of service when a tagged VLAN packet is received on that interface. (CVE-2010-4263, Important)

* A missing sanity check was found in vbd_create() in the Xen hypervisor implementation. As CD-ROM drives are not supported by the blkback back-end driver, attempting to use a virtual CD-ROM drive with blkback could trigger a denial of service (crash) on the host system running the Xen hypervisor. (CVE-2010-4238, Moderate)

* A flaw was found in the Linux kernel execve() system call implementation. A local, unprivileged user could cause large amounts of memory to be allocated but not visible to the OOM (Out of Memory) killer, triggering a denial of service. (CVE-2010-4243, Moderate)

* A flaw was found in fixup_page_fault() in the Xen hypervisor implementation. If a 64-bit para-virtualized guest accessed a certain area of memory, it could cause a denial of service on the host system running the Xen hypervisor. (CVE-2010-4255, Moderate)

* A missing initialization flaw was found in the bfa driver used by Brocade Fibre Channel Host Bus Adapters. A local, unprivileged user could use this flaw to cause a denial of service by reading a file in the '/sys/class/fc_host/host#/statistics/' directory. (CVE-2010-4343, Moderate)

* Missing initialization flaws in the Linux kernel could lead to information leaks. (CVE-2010-3296, CVE-2010-3877, CVE-2010-4072, CVE-2010-4073, CVE-2010-4075, CVE-2010-4080, CVE-2010-4081, CVE-2010-4158, Low)
