Summary

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.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    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-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

    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

    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

    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)

    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

    descriptionXEN has been updated to 4.1.5 c/s 23509 to fix various bugs and security issues. The following security issues have been fixed : - Certain page table manipulation operations in Xen 4.1.x, 4.2.x, and earlier were not preemptible, which allowed local PV kernels to cause a denial of service via vectors related to deep page table traversal. (CVE-2013-1918) - Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, did not properly check the source when accessing a bridge devices interrupt remapping table entries for MSI interrupts, which allowed local guest domains to cause a denial of service (interrupt injection) via unspecified vectors. (CVE-2013-1952) - A information leak in the XSAVE/XRSTOR instructions could be used to determine state of floating point operations in other domains. (CVE-2013-2076) - A denial of service (hypervisor crash) was possible due to missing exception recovery on XRSTOR, that could be used to crash the machine by PV guest users. (CVE-2013-2077) - A denial of service (hypervisor crash) was possible due to missing exception recovery on XSETBV, that could be used to crash the machine by PV guest users. (CVE-2013-2078) - Systems which allow untrusted administrators to configure guest vcpu affinity may be exploited to trigger a buffer overrun and corrupt memory. (CVE-2013-2072) - Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, did not clear the NT flag when using an IRET after a SYSENTER instruction, which allowed 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. (CVE-2013-1917) - Xen 4.2.x and 4.1.x did not properly restrict access to IRQs, which allowed local stub domain clients to gain access to IRQs and cause a denial of service via vectors related to
