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 in the dccp_rcv_state_process() function could allow a remote attacker to cause a denial of service, even when the socket was already closed. (CVE-2011-1093, Important) * Multiple buffer overflow flaws were found in the Linux kernel's Management Module Support for Message Passing Technology (MPT) based controllers. A local, unprivileged user could use these flaws to cause a denial of service, an information leak, or escalate their privileges. (CVE-2011-1494, CVE-2011-1495, Important) * A missing validation of a null-terminated string data structure element in the bnep_sock_ioctl() function could allow a local user to cause an information leak or a denial of service. (CVE-2011-1079, Moderate) * Missing error checking in the way page tables were handled in the Xen hypervisor implementation could allow a privileged guest user to cause the host, and the guests, to lock up. (CVE-2011-1166, Moderate) * A flaw was found in the way the Xen hypervisor implementation checked for the upper boundary when getting a new event channel port. A privileged guest user could use this flaw to cause a denial of service or escalate their privileges. (CVE-2011-1763, Moderate) * The start_code and end_code values in &quot /proc/[pid]/stat&quot were not protected. In certain scenarios, this flaw could be used to defeat Address Space Layout Randomization (ASLR). (CVE-2011-0726, Low) * A missing initialization flaw in the sco_sock_getsockopt() function could allow a local, unprivileged user to cause an information leak. (CVE-2011-1078, Low) * A missing validation of a null-terminated string data structure element in the do_replace() function could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1080, Low) * A buffer overflow flaw in the DEC Alpha OSF partition implementation in the Linux kernel could allow a local attacker to cause an information leak by mounting a disk that contains specially-crafted partition tables. (CVE-2011-1163, Low) * Missing validations of null-terminated string data structure elements in the do_replace(), compat_do_replace(), do_ipt_get_ctl(), do_ip6t_get_ctl(), and do_arpt_get_ctl() functions could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, Low) * A heap overflow flaw in the Linux kernel's EFI GUID Partition ... Description truncated, for more information please check the Reference URL
