Please Install the Updated Packages.

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 Unidirectional Lightweight Encapsulation (ULE) implementation. A remote attacker could send a specially-crafted ISO MPEG-2 Transport Stream (TS) frame to a target system, resulting in an infinite loop (denial of service). (CVE-2010-1086, Important) * on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate) * a flaw was found in the kernel connector implementation. A local, unprivileged user could trigger this flaw by sending an arbitrary number of notification requests using specially-crafted netlink messages, resulting in a denial of service. (CVE-2010-0410, Moderate) * a flaw was found in the Memory-mapped I/O (MMIO) instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which could crash the guest (denial of service). (CVE-2010-0730, Moderate) * a divide-by-zero flaw was found in the azx_position_ok() function in the driver for Intel High Definition Audio, snd-hda-intel. A local, unprivileged user could trigger this flaw to cause a kernel crash (denial of service). (CVE-2010-1085, Moderate) This update also fixes the following bugs: * in some cases, booting a system with the &quot iommu=on&quot kernel parameter resulted in a Xen hypervisor panic. (BZ#580199) * the fnic driver flushed the Rx queue instead of the Tx queue after fabric login. This caused crashes in some cases. (BZ#580829) * &quot kernel unaligned access&quot warnings were logged to the dmesg log on some systems. (BZ#580832) * the &quot Northbridge Error, node 1, core: -1 K8 ECC error&quot error occurred on some systems using the amd64_edac driver. (BZ#580836) * in rare circumstances, when using kdump and booting a kernel with &quot crashkernel=128M 16M&quot , the kdump kernel did not boot after a crash. (BZ#580838) * TLB page table entry flushing was done incorrectly on IBM System z, possibly causing crashes, subtle data inconsistency, or other issues. (BZ#580839) * iSCSI failover times were slower than in Red Hat Enterprise Linux 5.3. (BZ#580840) ... Description truncated, for more information please check the Reference URL
