    descriptionThe SUSE Linux Enterprise Server 11 Service Pack 1 LTSS Xen hypervisor and toolset have been updated to fix various security issues and some bugs. The following security issues have been addressed : XSA-84: CVE-2014-1894: Xen 3.2 (and presumably earlier) exhibit both problems with the overflow issue being present for more than just the suboperations listed above. (bnc#860163) XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through 4.1, while not affected by the above overflow, have a different overflow issue on FLASK_{GET,SET}BOOL and expose unreasonably large memory allocation to arbitrary guests. (bnc#860163) XSA-84: CVE-2014-1891: The FLASK_{GET,SET}BOOL, FLASK_USER and FLASK_CONTEXT_TO_SID suboperations of the flask hypercall are vulnerable to an integer overflow on the input size. The hypercalls attempt to allocate a buffer which is 1 larger than this size and is therefore vulnerable to integer overflow and an attempt to allocate then access a zero byte buffer. (bnc#860163) XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue. (bnc#853049) XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. (bnc#849668) XSA-74: CVE-2013-4553: The XEN_DOMCTL_getmemlist hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always obtain the page_alloc_lock and mm_rwlock in the same order, which allows local guest administrators to cause a denial of service (host deadlock). (bnc#849667) XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. (bnc#848657) XSA-67: CVE-2013-4368: The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. (bnc#842511) XSA-66: CVE-2013-4361: The fbld instruction emulation in Xen 3.3.x through 4.3.x does not use the correct variable for the source effective address, which allows local HVM guests to obtain hypervisor stack information by reading the values used by the instruction. (bnc#841766) XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. (bnc#840592) XSA-62: CVE-2013-1442: Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain sensitive information by reading the registers. (bnc#839596) XSA-61: CVE-2013-4329: The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction. (bnc#839618) XSA-60: CVE-2013-2212: The vmx_set_uc_mode function in Xen 3.3 through 4.3, when disabling chaches, allows local HVM guests with access to memory mapped I/O regions to cause a denial of service (CPU consumption and possibly hypervisor or guest kernel panic) via a crafted GFN range. (bnc#831120) XSA-58: CVE-2013-1918: Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier are not preemptible, which allows local PV kernels to cause a denial of service via vectors related to

    XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through 4.1,
    while not affected by the above overflow, have a different
    overflow issue on FLASK_{GET,SET}BOOL and expose
    unreasonably large memory allocation to arbitrary guests.
    (bnc#860163)
    
    XSA-84: CVE-2014-1891: The FLASK_{GET,SET}BOOL, FLASK_USER
    and FLASK_CONTEXT_TO_SID suboperations of the flask
    hypercall are vulnerable to an integer overflow on the input

    between locked instructions and write-combined memory types,
    which allows local users to cause a denial of service
    (system hang) via a crafted application, aka the errata 793
    issue. (bnc#853049)
    
    XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly
    4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1)
    does not properly prevent access to hypercalls, which allows
    local guest users to gain privileges via a crafted
    application running in ring 1 or 2. (bnc#849668)
    
    XSA-74: CVE-2013-4553: The XEN_DOMCTL_getmemlist hypercall
    in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always
    obtain the page_alloc_lock and mm_rwlock in the same order,
    which allows local guest administrators to cause a denial of
    service (host deadlock). (bnc#849667)
    
    XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x
    does not take the page_alloc_lock and grant_table.lock in
    the same order, which allows local guest administrators with
    access to multiple vcpus to cause a denial of service (host
    deadlock) via unspecified vectors. (bnc#848657)
    
    XSA-67: CVE-2013-4368: The outs instruction emulation in Xen
    3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS:
    segment override, uses an uninitialized variable as a
    segment base, which allows local 64-bit PV guests to obtain
    sensitive information (hypervisor stack content) via
    unspecified vectors related to stale data in a segment
    register. (bnc#842511)
    
    XSA-66: CVE-2013-4361: The fbld instruction emulation in Xen
    3.3.x through 4.3.x does not use the correct variable for
    the source effective address, which allows local HVM guests
    to obtain hypervisor stack information by reading the values
    used by the instruction. (bnc#841766)
    
    XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not
    properly handle certain errors, which allows local HVM
    guests to obtain hypervisor stack memory via a (1) port or
    (2) memory mapped I/O write or (3) other unspecified
    operations related to addresses without associated memory.
    (bnc#840592)
    
    XSA-62: CVE-2013-1442: Xen 4.0 through 4.3.x, when using AVX
    or LWP capable CPUs, does not properly clear previous data
    from registers when using an XSAVE or XRSTOR to extend the
    state components of a saved or restored vCPU after touching
    other restored extended registers, which allows local guest
    OSes to obtain sensitive information by reading the
    registers. (bnc#839596)
    
    XSA-61: CVE-2013-4329: The xenlight library (libxl) in Xen
    4.0.x through 4.2.x, when IOMMU is disabled, provides access
    to a busmastering-capable PCI passthrough device before the
    IOMMU setup is complete, which allows local HVM guest
    domains to gain privileges or cause a denial of service via
    a DMA instruction. (bnc#839618)
    
    XSA-60: CVE-2013-2212: The vmx_set_uc_mode function in Xen
    3.3 through 4.3, when disabling chaches, allows local HVM
    guests with access to memory mapped I/O regions to cause a
    denial of service (CPU consumption and possibly hypervisor
    or guest kernel panic) via a crafted GFN range. (bnc#831120)
    
    XSA-58: CVE-2013-1918: Certain page table manipulation
    operations in Xen 4.1.x, 4.2.x, and earlier are not
    preemptible, which allows local PV kernels to cause a denial
    of service via vectors related to 'deep page table
    traversal.' (bnc#826882)
    
    XSA-58: CVE-2013-1432: Xen 4.1.x and 4.2.x, when the XSA-45
    patch is in place, does not properly maintain references on
    pages stored for deferred cleanup, which allows local PV
    guest kernels to cause a denial of service (premature page
    free and hypervisor crash) or possible gain privileges via
    unspecified vectors. (bnc#826882)
    
    XSA-57: CVE-2013-2211: The libxenlight (libxl) toolstack
    library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions
    for xenstore keys for paravirtualised and emulated serial
    console devices, which allows local guest administrators to
    modify the xenstore value via unspecified vectors.
    (bnc#823608)
    
    XSA-56: CVE-2013-2072: Buffer overflow in the Python
    bindings for the xc_vcpu_setaffinity call in Xen 4.0.x,
    4.1.x, and 4.2.x allows local administrators with
    permissions to configure VCPU affinity to cause a denial of
    service (memory corruption and xend toolstack crash) and
    possibly gain privileges via a crafted cpumap. (bnc#819416)
    
    XSA-55: CVE-2013-2196: Multiple unspecified vulnerabilities
    in the Elf parser (libelf) in Xen 4.2.x and earlier allow
    local guest administrators with certain permissions to have
    an unspecified impact via a crafted kernel, related to
    'other problems' that are not CVE-2013-2194 or
    CVE-2013-2195. (bnc#823011)
    
    XSA-55: CVE-2013-2195: The Elf parser (libelf) in Xen 4.2.x
    and earlier allow local guest administrators with certain
    permissions to have an unspecified impact via a crafted
    kernel, related to 'pointer dereferences' involving
    unexpected calculations. (bnc#823011)
    
    XSA-55: CVE-2013-2194: Multiple integer overflows in the Elf
    parser (libelf) in Xen 4.2.x and earlier allow local guest
    administrators with certain permissions to have an
    unspecified impact via a crafted kernel. (bnc#823011)
    
    XSA-53: CVE-2013-2077: Xen 4.0.x, 4.1.x, and 4.2.x does not
    properly restrict the contents of a XRSTOR, which allows
    local PV guest users to cause a denial of service (unhandled
    exception and hypervisor crash) via unspecified vectors.
    (bnc#820919)
    
    XSA-52: CVE-2013-2076: Xen 4.0.x, 4.1.x, and 4.2.x, when
    running on AMD64 processors, only save/restore the FOP, FIP,
    and FDP x87 registers in FXSAVE/FXRSTOR when an exception is
    pending, which allows one domain to determine portions of
    the state of floating point instructions of other domains,
    which can be leveraged to obtain sensitive information such
    as cryptographic keys, a similar vulnerability to
    CVE-2006-1056. NOTE: this is the documented behavior of
    AMD64 processors, but it is inconsistent with Intel
    processors in a security-relevant fashion that was not
    addressed by the kernels. (bnc#820917)
    
    XSA-50: CVE-2013-1964: Xen 4.0.x and 4.1.x incorrectly
    releases a grant reference when releasing a non-v1,
    non-transitive grant, which allows local guest
    administrators to cause a denial of service (host crash),
    obtain sensitive information, or possible have other impacts
    via unspecified vectors. (bnc#816156)
    
    XSA-49: CVE-2013-1952: Xen 4.x, when using Intel VT-d for a
    bus mastering capable PCI device, does not properly check
    the source when accessing a bridge device's interrupt
    remapping table entries for MSI interrupts, which allows
    local guest domains to cause a denial of service (interrupt
    injection) via unspecified vectors. (bnc#816163)
    
    XSA-47: CVE-2013-1920: Xen 4.2.x, 4.1.x, and earlier, when
    the hypervisor is running 'under memory pressure' and the
    Xen Security Module (XSM) is enabled, uses the wrong
    ordering of operations when extending the per-domain event
    channel tracking table, which causes a use-after-free and
    allows local guest kernels to inject arbitrary events and
    gain privileges via unspecified vectors. (bnc#813677)
    
    XSA-46: CVE-2013-1919: Xen 4.2.x and 4.1.x does not properly
    restrict access to IRQs, which allows local stub domain
    clients to gain access to IRQs and cause a denial of service
    via vectors related to 'passed-through IRQs or PCI devices.'
    (bnc#813675)
    
    XSA-45: CVE-2013-1918: Certain page table manipulation
    operations in Xen 4.1.x, 4.2.x, and earlier are not
    preemptible, which allows local PV kernels to cause a denial
    of service via vectors related to 'deep page table
    traversal.' (bnc#816159)
    
    XSA-44: CVE-2013-1917: Xen 3.1 through 4.x, when running
    64-bit hosts on Intel CPUs, does not clear the NT flag when
    using an IRET after a SYSENTER instruction, which allows PV
    guest users to cause a denial of service (hypervisor crash)
    by triggering a #GP fault, which is not properly handled by
    another IRET instruction. (bnc#813673)
    
    XSA-41: CVE-2012-6075: Buffer overflow in the e1000_receive
    function in the e1000 device driver (hw/e1000.c) in QEMU
    1.3.0-rc2 and other versions, when the SBP and LPE flags are
    disabled, allows remote attackers to cause a denial of
    service (guest OS crash) and possibly execute arbitrary
    guest code via a large packet. (bnc#797523)
    
    XSA-37: CVE-2013-0154: The get_page_type function in
    xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled,
    allows local PV or HVM guest administrators to cause a
    denial of service (assertion failure and hypervisor crash)
    via unspecified vectors related to a hypercall. (bnc#797031)
    
    XSA-36: CVE-2013-0153: The AMD IOMMU support in Xen 4.2.x,
    4.1.x, 3.3, and other versions, when using AMD-Vi for PCI
    passthrough, uses the same interrupt remapping table for the
    host and all guests, which allows guests to cause a denial
    of service by injecting an interrupt into other guests.
    (bnc#800275)
    
    XSA-33: CVE-2012-5634: Xen 4.2.x, 4.1.x, and 4.0, when using
    Intel VT-d for PCI passthrough, does not properly configure
    VT-d when supporting a device that is behind a legacy PCI
    Bridge, which allows local guests to cause a denial of
    service to other guests by injecting an interrupt.
    (bnc#794316)
    
    XSA-31: CVE-2012-5515: The (1) XENMEM_decrease_reservation,
    (2) XENMEM_populate_physmap, and (3) XENMEM_exchange
    hypercalls in Xen 4.2 and earlier allow local guest
    administrators to cause a denial of service (long loop and
    hang) via a crafted extent_order value. (bnc#789950)
    
    XSA-30: CVE-2012-5514: The
    guest_physmap_mark_populate_on_demand function in Xen 4.2
    and earlier does not properly unlock the subject GFNs when
    checking if they are in use, which allows local guest HVM
    administrators to cause a denial of service (hang) via
    unspecified vectors. (bnc#789948)
    
    XSA-29: CVE-2012-5513: The XENMEM_exchange handler in Xen
    4.2 and earlier does not properly check the memory address,
    which allows local PV guest OS administrators to cause a
    denial of service (crash) or possibly gain privileges via
    unspecified vectors that overwrite memory in the hypervisor
    reserved range. (bnc#789951)
    
    XSA-27: CVE-2012-6333: Multiple HVM control operations in
    Xen 3.4 through 4.2 allow local HVM guest OS administrators
    to cause a denial of service (physical CPU consumption) via
    a large input. (bnc#789944)
    
    XSA-27: CVE-2012-5511: Stack-based buffer overflow in the
    dirty video RAM tracking functionality in Xen 3.4 through
    4.1 allows local HVM guest OS administrators to cause a
    denial of service (crash) via a large bitmap image.
    (bnc#789944)
    
    XSA-26: CVE-2012-5510: Xen 4.x, when downgrading the grant
    table version, does not properly remove the status page from
    the tracking list when freeing the page, which allows local
    guest OS administrators to cause a denial of service
    (hypervisor crash) via unspecified vectors. (bnc#789945)
    
    XSA-25: CVE-2012-4544: The PV domain builder in Xen 4.2 and
    earlier does not validate the size of the kernel or ramdisk
    (1) before or (2) after decompression, which allows local
    guest administrators to cause a denial of service (domain 0
    memory consumption) via a crafted (a) kernel or (b) ramdisk.
    (bnc#787163)
    
    XSA-24: CVE-2012-4539: Xen 4.0 through 4.2, when running
    32-bit x86 PV guests on 64-bit hypervisors, allows local
    guest OS administrators to cause a denial of service
    (infinite loop and hang or crash) via invalid arguments to
    GNTTABOP_get_status_frames, aka 'Grant table hypercall
    infinite loop DoS vulnerability.' (bnc#786520)
    
    XSA-23: CVE-2012-4538: The HVMOP_pagetable_dying hypercall
    in Xen 4.0, 4.1, and 4.2 does not properly check the
    pagetable state when running on shadow pagetables, which
    allows a local HVM guest OS to cause a denial of service
    (hypervisor crash) via unspecified vectors. (bnc#786519)
    
    XSA-22: CVE-2012-4537: Xen 3.4 through 4.2, and possibly
    earlier versions, does not properly synchronize the p2m and
    m2p tables when the set_p2m_entry function fails, which
    allows local HVM guest OS administrators to cause a denial
    of service (memory consumption and assertion failure), aka
    'Memory mapping failure DoS vulnerability.' (bnc#786517)
    
    XSA-20: CVE-2012-4535: Xen 3.4 through 4.2, and possibly
    earlier versions, allows local guest OS administrators to
    cause a denial of service (Xen infinite loop and physical
    CPU consumption) by setting a VCPU with an 'inappropriate
    deadline.' (bnc#786516)
    
    XSA-19: CVE-2012-4411: The graphical console in Xen 4.0, 4.1
    and 4.2 allows local OS guest administrators to obtain
    sensitive host resource information via the qemu monitor.
    NOTE: this might be a duplicate of CVE-2007-0998.
    (bnc#779212)
    
    XSA-15: CVE-2012-3497: (1) TMEMC_SAVE_GET_CLIENT_WEIGHT, (2)
    TMEMC_SAVE_GET_CLIENT_CAP, (3) TMEMC_SAVE_GET_CLIENT_FLAGS
    and (4) TMEMC_SAVE_END in the Transcendent Memory (TMEM) in
    Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a
    denial of service (NULL pointer dereference or memory
    corruption and host crash) or possibly have other
    unspecified impacts via a NULL client id. (bnc#777890)
    
    Also the following non-security bugs have been fixed :
    
      - xen hot plug attach/detach fails modified
        blktap-pv-cdrom.patch. (bnc#805094)
    
      - guest 'disappears' after live migration Updated
        block-dmmd script. (bnc#777628)

    "The SUSE Linux Enterprise 10 Service Pack 3 LTSS Xen hypervisor and
    toolset have been updated to fix various security issues :
    
    The following security issues have been addressed :
    
    XSA-20: CVE-2012-4535: Xen 3.4 through 4.2, and possibly earlier
    versions, allows local guest OS administrators to cause a denial of
    service (Xen infinite loop and physical CPU consumption) by setting a
    VCPU with an 'inappropriate deadline'. (bnc#786516)
    
    XSA-22: CVE-2012-4537: Xen 3.4 through 4.2, and possibly
    earlier versions, does not properly synchronize the p2m and
    m2p tables when the set_p2m_entry function fails, which
    allows local HVM guest OS administrators to cause a denial
    of service (memory consumption and assertion failure), aka
    'Memory mapping failure DoS vulnerability'. (bnc#786517)
    
    XSA-25: CVE-2012-4544: The PV domain builder in Xen 4.2 and
    earlier does not validate the size of the kernel or ramdisk
    (1) before or (2) after decompression, which allows local
    guest administrators to cause a denial of service (domain 0
    memory consumption) via a crafted (a) kernel or (b) ramdisk.
    (bnc#787163)
    
    XSA-29: CVE-2012-5513: The XENMEM_exchange handler in Xen
    4.2 and earlier does not properly check the memory address,
    which allows local PV guest OS administrators to cause a
    denial of service (crash) or possibly gain privileges via
    unspecified vectors that overwrite memory in the hypervisor
    reserved range. (bnc#789951)
    
    XSA-31: CVE-2012-5515: The (1) XENMEM_decrease_reservation,
    (2) XENMEM_populate_physmap, and (3) XENMEM_exchange
    hypercalls in Xen 4.2 and earlier allow local guest
    administrators to cause a denial of service (long loop and
    hang) via a crafted extent_order value. (bnc#789950)
    
    XSA-44: CVE-2013-1917: Xen 3.1 through 4.x, when running
    64-bit hosts on Intel CPUs, does not clear the NT flag when
    using an IRET after a SYSENTER instruction, which allows PV
    guest users to cause a denial of service (hypervisor crash)
    by triggering a #GP fault, which is not properly handled by
    another IRET instruction. (bnc#813673)
    
    XSA-47: CVE-2013-1920: Xen 4.2.x, 4.1.x, and earlier, when
    the hypervisor is running 'under memory pressure' and the
    Xen Security Module (XSM) is enabled, uses the wrong
    ordering of operations when extending the per-domain event
    channel tracking table, which causes a use-after-free and
    allows local guest kernels to inject arbitrary events and
    gain privileges via unspecified vectors. (bnc#813677)
    
    XSA-55: CVE-2013-2196: Multiple unspecified vulnerabilities
    in the Elf parser (libelf) in Xen 4.2.x and earlier allow
    local guest administrators with certain permissions to have
    an unspecified impact via a crafted kernel, related to
    'other problems' that are not CVE-2013-2194 or
    CVE-2013-2195. (bnc#823011)
    
    XSA-55: CVE-2013-2195: The Elf parser (libelf) in Xen 4.2.x
    and earlier allow local guest administrators with certain
    permissions to have an unspecified impact via a crafted
    kernel, related to 'pointer dereferences' involving
    unexpected calculations. (bnc#823011)
    
    XSA-55: CVE-2013-2194: Multiple integer overflows in the Elf
    parser (libelf) in Xen 4.2.x and earlier allow local guest
    administrators with certain permissions to have an
    unspecified impact via a crafted kernel. (bnc#823011)
    
    XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not
    properly handle certain errors, which allows local HVM
    guests to obtain hypervisor stack memory via a (1) port or
    (2) memory mapped I/O write or (3) other unspecified
    operations related to addresses without associated memory.
    (bnc#840592)
    
    XSA-67: CVE-2013-4368: The outs instruction emulation in Xen
    3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS:
    segment override, uses an uninitialized variable as a
    segment base, which allows local 64-bit PV guests to obtain
    sensitive information (hypervisor stack content) via
    unspecified vectors related to stale data in a segment
    register. (bnc#842511)
    
    XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x
    does not take the page_alloc_lock and grant_table.lock in
    the same order, which allows local guest administrators with
    access to multiple vcpus to cause a denial of service (host
    deadlock) via unspecified vectors. (bnc#848657)
    
    XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly
    4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1)
    does not properly prevent access to hypercalls, which allows
    local guest users to gain privileges via a crafted
    application running in ring 1 or 2. (bnc#849668)
    
    XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through
    0Fh processors does not properly handle the interaction
    between locked instructions and write-combined memory types,
    which allows local users to cause a denial of service
    (system hang) via a crafted application, aka the errata 793
    issue. (bnc#853049)

    description block directly from the SUSE security advisory. Tenable
    has attempted to automatically clean and format it as much as possible

    descriptionThe remote host is affected by the vulnerability described in GLSA-201309-24 (Xen: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details. Impact : Guest domains could possibly gain privileges, execute arbitrary code, or cause a Denial of Service on the host domain (Dom0). Additionally, guest domains could gain information about other virtual machines running on the same host or read arbitrary files on the host. Workaround : The CVEs listed below do not currently have fixes, but only apply to Xen setups which have &ldquo;tmem&rdquo; specified on the hypervisor command line. TMEM is not currently supported for use in production systems, and administrators using tmem should disable it. Relevant CVEs: * CVE-2012-2497 * CVE-2012-6030 * CVE-2012-6031 * CVE-2012-6032 * CVE-2012-6033 * CVE-2012-6034 * CVE-2012-6035 * CVE-2012-6036

        Multiple vulnerabilities have been discovered in Xen. Please review the
          CVE identifiers referenced below for details.
      
    Impact :
    
        Guest domains could possibly gain privileges, execute arbitrary code, or
          cause a Denial of Service on the host domain (Dom0). Additionally, guest
          domains could gain information about other virtual machines running on
          the same host or read arbitrary files on the host.
      
    Workaround :
    
        The CVEs listed below do not currently have fixes, but only apply to Xen
          setups which have &ldquo;tmem&rdquo; specified on the hypervisor command line.
          TMEM is not currently supported for use in production systems, and
          administrators using tmem should disable it.
          Relevant CVEs:
          * CVE-2012-2497
          * CVE-2012-6030
          * CVE-2012-6031

    descriptionThe SUSE Linux Enterprise Server 10 Service Pack 4 LTSS Xen hypervisor and toolset have been updated to fix various security issues. The following security issues have been addressed : - XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through 0Fh processors does not properly handle the interaction between locked instructions and write-combined memory types, which allows local users to cause a denial of service (system hang) via a crafted application, aka the errata 793 issue. (bnc#853049) - XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1) does not properly prevent access to hypercalls, which allows local guest users to gain privileges via a crafted application running in ring 1 or 2. (bnc#849668) - XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x does not take the page_alloc_lock and grant_table.lock in the same order, which allows local guest administrators with access to multiple vcpus to cause a denial of service (host deadlock) via unspecified vectors. (bnc#848657) - XSA-67: CVE-2013-4368: The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register. (bnc#842511) - XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. (bnc#840592) - XSA-55: CVE-2013-2196: Multiple unspecified vulnerabilities in the Elf parser (libelf) in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to
