Summary

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.

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

    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

    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

    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

    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,

    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

    "The remote OracleVM system is missing necessary patches to address
    critical security updates :
    
      - libxc: builder: limit maximum size of kernel/ramdisk.
        Allowing user supplied kernels of arbitrary sizes,
        especially during decompression, can swallow up dom0
        memory leading to either virtual address space
        exhaustion in the builder process or allocation
        failures/OOM killing of both toolstack and unrelated
        processes. We disable these checks when building in a
        stub domain for pvgrub since this uses the guest's own
        memory and is isolated. Decompression of gzip compressed
        kernels and ramdisks has been safe since
        14954:58205257517d (Xen 3.1.0 onwards). This is XSA-25 /
        CVE-2012-4544. Also make explicit checks for buffer
        overflows in various decompression routines. These were
        already ruled out due to other properties of the code
        but check them as a belt-and-braces measure.
    
        [ Includes 25589:60f09d1ab1fe for CVE-2012-2625]
        (CVE-2012-4544)
    
      - compat/gnttab: Prevent infinite loop in compat code c/s
        20281:95ea2052b41b, which introduces Grant Table version
        2 hypercalls introduces a vulnerability whereby the
        compat hypercall handler can fall into an infinite loop.
        If the watchdog is enabled, Xen will die after the
        timeout. This is a security problem, XSA-24 /
        CVE-2012-4539. (CVE-2012-4539)
    
      - xen/mm/shadow: check toplevel pagetables are present
        before unhooking them. If the guest has not fully
        populated its top-level PAE entries when it calls
        HVMOP_pagetable_dying, the shadow code could try to
        unhook entries from MFN 0. Add a check to avoid that
        case. This issue was introduced by c/s
        21239:b9d2db109cf5. This is a security problem, XSA-23 /
        CVE-2012-4538. (CVE-2012-4538)
    
      - x86/physmap: Prevent incorrect updates of m2p mappings
        In certain conditions, such as low memory, set_p2m_entry
        can fail. Currently, the p2m and m2p tables will get out
        of sync because we still update the m2p table after the
        p2m update has failed. If that happens, subsequent
        guest-invoked memory operations can cause BUGs and
        ASSERTs to kill Xen. This is fixed by only updating the
        m2p table iff the p2m was successfully updated. This is
        a security problem, XSA-22 / CVE-2012-4537.
        (CVE-2012-4537)
    
      - x86/physdev: Range check pirq parameter from guests
        Otherwise Xen will read beyond either end of the struct
        domain.arch.pirq_emuirq array, usually resulting in a
        fatal page fault. This vulnerability was introduced by
        c/s 23241:d21100f1d00e, which adds a call to
        domain_pirq_to_emuirq which uses the guest provided pirq
        value before range checking it, and was fixed by c/s
        23573:584c2e5e03d9 which changed the behaviour of the
        domain_pirq_to_emuirq macro to use radix trees instead
        of a flat array. This is XSA-21 / CVE-2012-4536.
        (CVE-2012-4536)
    
      - VCPU/timers: Prevent overflow in calculations, leading
        to DoS vulnerability The timer action for a vcpu
        periodic timer is to calculate the next expiry time, and
        to reinsert itself into the timer queue. If the deadline
        ends up in the past, Xen never leaves __do_softirq. The
        affected PCPU will stay in an infinite loop until Xen is
        killed by the watchdog (if enabled). This is a security
        problem, XSA-20 / CVE-2012-4535. (CVE-2012-4535)
    
      - Correct RTC time offset update error for HVM guest
        changeset 24947:b198ada9689d
    
      - always release vm running lock on VM shutdown Before
        this patch, when xend restarted, the VM running lock
        will not be released on shutdown, so the VM could never
        start again. Talked with Junjie, we recommend always
        releasing the lock on VM shutdown. So even when xend
        restarted, there should be no stale lock leaving there."

  • NASL familyDebian Local Security Checks
    NASL idDEBIAN_DSA-2582.NASL
    descriptionMultiple denial of service vulnerabilities have been discovered in the Xen Hypervisor. One of the issue (CVE-2012-5513 ) could even lead to privilege escalation from guest to host. Some of the recently published Xen Security Advisories ( XSA 25and 28) are not fixed by this update and should be fixed in a future release. - CVE-2011-3131 ( XSA 5): DoS using I/OMMU faults from PCI-passthrough guest A VM that controls a PCI[E] device directly can cause it to issue DMA requests to invalid addresses. Although these requests are denied by the I/OMMU, the hypervisor needs to handle the interrupt and clear the error from the I/OMMU, and this can be used to live-lock a CPU and potentially hang the host. - CVE-2012-4535 ( XSA 20): Timer overflow DoS vulnerability A guest which sets a VCPU with an inappropriate deadline can cause an infinite loop in Xen, blocking the affected physical CPU indefinitely. - CVE-2012-4537 ( XSA 22): Memory mapping failure DoS vulnerability When set_p2m_entry fails, Xen

    descriptionThe remote OracleVM system is missing necessary patches to address critical security updates : - compat/gnttab: Prevent infinite loop in compat code c/s 20281:95ea2052b41b, which introduces Grant Table version 2 hypercalls introduces a vulnerability whereby the compat hypercall handler can fall into an infinite loop. If the watchdog is enabled, Xen will die after the timeout. This is a security problem, XSA-24 / CVE-2012-4539. (CVE-2012-4539) - xen/mm/shadow: check toplevel pagetables are present before unhooking them. If the guest has not fully populated its top-level PAE entries when it calls HVMOP_pagetable_dying, the shadow code could try to unhook entries from MFN 0. Add a check to avoid that case. This issue was introduced by c/s 21239:b9d2db109cf5. This is a security problem, XSA-23 / CVE-2012-4538. (CVE-2012-4538) - x86/physmap: Prevent incorrect updates of m2p mappings In certain conditions, such as low memory, set_p2m_entry can fail. Currently, the p2m and m2p tables will get out of sync because we still update the m2p table after the p2m update has failed. If that happens, subsequent guest-invoked memory operations can cause BUGs and ASSERTs to kill Xen. This is fixed by only updating the m2p table iff the p2m was successfully updated. This is a security problem, XSA-22 / CVE-2012-4537. (CVE-2012-4537) - VCPU/timers: Prevent overflow in calculations, leading to DoS vulnerability The timer action for a vcpu periodic timer is to calculate the next expiry time, and to reinsert itself into the timer queue. If the deadline ends up in the past, Xen never leaves __do_softirq. The affected PCPU will stay in an infinite loop until Xen is killed by the watchdog (if enabled). This is a security problem, XSA-20 / CVE-2012-4535. (CVE-2012-4535) - always release vm running lock on VM shutdown Before this patch, when xend restarted, the VM running lock will not be released on shutdown, so the VM could never start again. Talked with Junjie, we recommend always releasing the lock on VM shutdown. So even when xend restarted, there should be no stale lock leaving there. - Xen Security Advisory CVE-2012-4411 / XSA-19 version 2 guest administrator can access qemu monitor console Disable qemu monitor by default. The qemu monitor is an overly powerful feature which must be protected from untrusted (guest) administrators. (CVE-2012-4411)
