    linux-ti-omap4 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.10
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-ti-omap4: Linux kernel for OMAP4
    
    Details:
    
    Mathy Vanhoef discovered an error in the the way the ath9k driver was
    handling the BSSID masking. A remote attacker could exploit this error to
    discover the original MAC address after a spoofing atack. (CVE-2013-4579)
    
    Andrew Honig reported a flaw in the Linux Kernel's kvm_vm_ioctl_create_vcpu
    function of the Kernel Virtual Machine (KVM) subsystem. A local user could
    exploit this flaw to gain privileges on the host machine. (CVE-2013-4587)
    
    Andrew Honig reported a flaw in the apic_get_tmcct function of the Kernel
    Virtual Machine (KVM) subsystem if the Linux kernel. A guest OS user could
    exploit this flaw to cause a denial of service or host OS system crash.
    (CVE-2013-6367)
    
    Andrew Honig reported an error in the Linux Kernel's Kernel Virtual Machine
    (KVM) VAPIC synchronization operation. A local user could exploit this flaw
    to gain privileges or cause a denial of service (system crash).
    (CVE-2013-6368)
    
    Nico Golde and Fabian Yamaguchi reported buffer underflow errors in the
    implementation of the XFS filesystem in the Linux kernel. A local user with
    CAP_SYS_ADMIN could exploit these flaw to cause a denial of service (memory
    corruption) or possibly other unspecified issues. (CVE-2013-6382)
    
    mpd reported an information leak in the recvfrom, recvmmsg, and recvmsg
    system calls in the Linux kernel. An unprivileged local user could exploit
    this flaw to obtain sensitive information from kernel stack memory.
    (CVE-2013-7263)
    
    mpb reported an information leak in the Layer Two Tunneling Protocol (l2tp)
    of the Linux kernel. A local user could exploit this flaw to obtain
    sensitive information from kernel stack memory. (CVE-2013-7264)
    
    mpb reported an information leak in the Phone Network protocol (phonet) in
    the Linux kernel. A local user could exploit this flaw to obtain sensitive
    information from kernel stack memory. (CVE-2013-7265)
    
    An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
    systemcalls when used with ISDN sockets in the Linux kernel. A local user
    could exploit this leak to obtain potentially sensitive information from
    kernel memory. (CVE-2013-7266)
    
    An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
    systemcalls when used with apple talk sockets in the Linux kernel. A local
    user could exploit this leak to obtain potentially sensitive information
    from kernel memory. (CVE-2013-7267)
    
    An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
    systemcalls when used with ipx protocol sockets in the Linux kernel. A
    local user could exploit this leak to obtain potentially sensitive
    information from kernel memory. (CVE-2013-7268)
    
    An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
    systemcalls when used with the netrom address family in the Linux kernel. A
    local user could exploit this leak to obtain potentially sensitive
    information from kernel memory. (CVE-2013-7269)
    
    An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
    systemcalls when used with packet address family sockets in the Linux
    kernel. A local user could exploit this leak to obtain potentially
    sensitive information from kernel memory. (CVE-2013-7270)
    
    An information leak was discovered in the recvfrom, recvmmsg, and recvmsg
    systemcalls when used with x25 protocol sockets in the Linux kernel. A
    local user could exploit this leak to obtain potentially sensitive
    information from kernel memory. (CVE-2013-7271)
    
    mpb reported an information leak in the Low-Rate Wireless Personal Area
    Networks support (IEEE 802.15.4) in the Linux kernel. A local user could
    exploit this flaw to obtain sensitive information from kernel stack memory.
    (CVE-2013-7281)
    
    halfdog reported an error in the AMD K7 and K8 platform support in the
    Linux kernel. An unprivileged local user could exploit this flaw on AMD
    based systems to cause a denial of service (task kill) or possibly gain
    privileges via a crafted application. (CVE-2014-1438)
    
    An information leak was discovered in the Linux kernel's hamradio YAM
    driver for AX.25 packet radio. A local user with the CAP_NET_ADMIN
    capability could exploit this flaw to obtain sensitive information from
    kernel memory. (CVE-2014-1446)
    
    Matthew Thode reported a denial of service vulnerability in the Linux
    kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN
    capability (and the SELinux mac_admin permission if running in enforcing
    mode) could exploit this flaw to cause a denial of service (kernel crash).
    (CVE-2014-1874)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 13.10:
      linux-image-3.5.0-239-omap4     3.5.0-239.55
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed. If
    you use linux-restricted-modules, you have to update that package as
    well to get modules which work with the new kernel version. Unless you
    manually uninstalled the standard kernel metapackages (e.g. linux-generic,
    linux-server, linux-powerpc), a standard system upgrade will automatically
    perform this as well.
