    Several vulnerabilities have been discovered in the Linux kernel that may lead
    to a denial of service, information leak or privilege escalation. The Common
    Vulnerabilities and Exposures project identifies the following problems:
    
    CVE-2013-0343
    
        George Kargiotakis reported an issue in the temporary address handling
        of the IPv6 privacy extensions. Users on the same LAN can cause a denial
        of service or obtain access to sensitive information by sending router
        advertisement messages that cause temporary address generation to be
        disabled.
    
    CVE-2013-2147
    
        Dan Carpenter reported issues in the cpqarray driver for Compaq
        Smart2 Controllers and the cciss driver for HP Smart Array controllers
        allowing users to gain access to sensitive kernel memory.
    
    CVE-2013-2889
    
        Kees Cook discovered missing input sanitization in the HID driver for
        Zeroplus game pads that could lead to a local denial of service.
    
    CVE-2013-2893
    
        Kees Cook discovered that missing input sanitization in the HID driver
        for various Logitech force feedback devices could lead to a local denial
        of service.
    
    CVE-2013-2929
    
        Vasily Kulikov discovered that a flaw in the get_dumpable() function of
        the ptrace subsytsem could lead to information disclosure. Only systems
        with the fs.suid_dumpable sysctl set to a non-default value of '2' are
        vulnerable.
    
    CVE-2013-4162
    
        Hannes Frederic Sowa discovered that incorrect handling of IPv6 sockets
        using the UDP_CORK option could result in denial of service.
    
    CVE-2013-4299
    
        Fujitsu reported an issue in the device-mapper subsystem. Local users
        could gain access to sensitive kernel memory.
    
    CVE-2013-4345
    
        Stephan Mueller found in bug in the ANSI pseudo random number generator
        which could lead to the use of less entropy than expected.
    
    CVE-2013-4512
    
        Nico Golde and Fabian Yamaguchi reported an issue in the user mode
        linux port. A buffer overflow condition exists in the write method
        for the /proc/exitcode file. Local users with sufficient privileges
        allowing them to write to this file could gain further elevated
        privileges.
    
    CVE-2013-4587
    
        Andrew Honig of Google reported an issue in the KVM virtualization
        subsystem. A local user could gain elevated privileges by passing
        a large vcpu_id parameter.
    
    CVE-2013-6367
    
        Andrew Honig of Google reported an issue in the KVM virtualization
        subsystem. A divide-by-zero condition could allow a guest user to
        cause a denial of service on the host (crash).
    
    CVE-2013-6380
    
        Mahesh Rajashekhara reported an issue in the aacraid driver for storage
        products from various vendors. Local users with CAP_SYS_ADMIN privileges
        could gain further elevated privileges.
    
    CVE-2013-6381
    
        Nico Golde and Fabian Yamaguchi reported an issue in the Gigabit Ethernet
        device support for s390 systems. Local users could cause a denial of
        service or gain elevated privileges via the SIOC_QETH_ADP_SET_SNMP_CONTROL
        ioctl.
    
    CVE-2013-6382
    
        Nico Golde and Fabian Yamaguchi reported an issue in the XFS filesystem.
        Local users with CAP_SYS_ADMIN privileges could gain further elevated
        privileges.
    
    CVE-2013-6383
    
        Dan Carpenter reported an issue in the aacraid driver for storage devices
        from various vendors. A local user could gain elevated privileges due to
        a missing privilege level check in the aac_compat_ioctl function.
    
    CVE-2013-7263 CVE-2013-7264 CVE-2013-7265
    
        mpb reported an information leak in the recvfrom, recvmmsg and recvmsg
        system calls. A local user could obtain access to sensitive kernel memory.
    
    CVE-2013-7339
    
        Sasha Levin reported an issue in the RDS network protocol over Infiniband.
        A local user could cause a denial of service condition.
    
    CVE-2014-0101
    
        Nokia Siemens Networks reported an issue in the SCTP network protocol
        subsystem. Remote users could cause a denial of service (NULL pointer
        dereference).
    
    CVE-2014-1444
    
        Salva Peiro reported an issue in the FarSync WAN driver. Local users
        with the CAP_NET_ADMIN capability could gain access to sensitive kernel
        memory.
    
    CVE-2014-1445
    
        Salva Peiro reported an issue in the wanXL serial card driver. Local
        users could gain access to sensitive kernel memory.
    
    CVE-2014-1446
    
        Salva Peiro reported an issue in the YAM radio modem driver. Local users
        with the CAP_NET_ADMIN capability could gain access to sensitive kernel
        memory.
    
    CVE-2014-1874
    
        Matthew Thode reported an issue in the SELinux subsystem. A local user
        with CAP_MAC_ADMIN privileges could cause a denial of service by setting
        an empty security context on a file.
        
    CVE-2014-2039
    
        Martin Schwidefsky reported an issue on s390 systems. A local user
        could cause a denial of service (kernel oops) by executing an application
        with a linkage stack instruction.
    
    CVE-2014-2523
    
        Daniel Borkmann provided a fix for an issue in the nf_conntrack_dccp
        module. Remote users could cause a denial of service (system crash)
        or potentially gain elevated privileges.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 2.6.32-48squeeze5.
    
    The following matrix lists additional source packages that were rebuilt for
    compatibility with or to take advantage of this update:
    
                                                 Debian 6.0 (squeeze)
         user-mode-linux                         2.6.32-1um-4+48squeeze5
    
    We recommend that you upgrade your linux-2.6 and user-mode-linux packages.
    
    Note: Debian carefully tracks all known security issues across every
    linux kernel package in all releases under active security support.
    However, given the high frequency at which low-severity security
    issues are discovered in the kernel and the resource requirements of
    doing an update, updates for lower priority issues will normally not
    be released for all kernels at the same time. Rather, they will be
    released in a staggered or "leap-frog" fashion.
