Summary: Updated kernel-linus package fixes multiple vulnerabilities

Details: This kernel update provides an update to the 3.10 longterm branch, currently 3.10.28 and fixes the following security issues: The ath9k_htc_set_bssid_mask function in drivers/net/wireless/ath/ath9k/htc_drv_main.c in the Linux kernel through 3.12 uses a BSSID masking approach to determine the set of MAC addresses on which a Wi-Fi device is listening, which allows remote attackers to discover the original MAC address after spoofing by sending a series of packets to MAC addresses with certain bit manipulations. (CVE-2013-4579) Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value (CVE-2013-4587) The apic_get_tmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via crafted modifications of the TMICT value. (CVE-2013-6367) The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address. (CVE-2013-6368) The recalculate_apic_map function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (host OS crash) via a crafted ICR write operation in x2apic mode. (CVE-2013-6376) Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c. (CVE-2013-6382) Pageexec reported a bug in the Linux kernel's recvmmsg syscall when called from code using the x32 ABI. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrator privileges (CVE-2014-0038) Faults during task-switch due to unhandled FPU-exceptions allow to kill processes at random on all affected kernels, resulting in local DOS in the end. One some architectures, privilege escalation under non-common circumstances is possible. (CVE-2014-1438) The hamradio yam_ioctl() code fails to initialise the cmd field of the struct yamdrv_ioctl_cfg leading to a 4-byte info leak. (CVE-2014-1446) Linux kernel built with the NetFilter Connection Tracking(NF_CONNTRACK) support for IRC protocol(NF_NAT_IRC), is vulnerable to an information leakage flaw. It could occur when communicating over direct client-to-client IRC connection(/dcc) via a NAT-ed network. Kernel attempts to mangle IRC TCP packet's content, wherein an uninitialised 'buffer' object is copied to a socket buffer and sent over to the other end of a connection. (CVE-2014-1690) For other changes, see the referenced changelogs:
