"The remote VMware ESXi 5.1 host is affected by the following security
vulnerabilities :

  - An integer overflow condition exists in the glibc
    library in the __tzfile_read() function that allows a
    denial of service or arbitrary code execution.
    (CVE-2009-5029)

  - An error exists in the glibc library related to modified
    loaders and 'LD_TRACE_LOADED_OBJECTS' checks that allow
    arbitrary code execution. This issue is disputed by the
    creators of glibc. (CVE-2009-5064)

  - An integer signedness error exists in the
    elf_get_dynamic_info() function in elf/dynamic-link.h
    that allows arbitrary code execution. (CVE-2010-0830)

  - An error exists in the glibc library in the addmntent()
    function that allows a corruption of the '/etc/mtab'
    file. (CVE-2011-1089)

  - An error exists in the libxslt library in the
    xsltGenerateIdFunction() function that allows the
    disclosure of sensitive information. (CVE-2011-1202)

  - An off-by-one overflow condition exists in the
    xmlXPtrEvalXPtrPart() function due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted XML file, to cause a denial of service condition
    or the execution of arbitrary code. (CVE-2011-3102)

  - An out-of-bounds read error exists in the libxslt
    library in the xsltCompilePatternInternal() function
    that allows a denial of service. (CVE-2011-3970)

  - An error exists in the glibc library in the svc_run()
    function that allows a denial of service.
    (CVE-2011-4609)

  - An overflow error exists in the glibc library in the
    printf() function related to 'nargs' parsing that allows
    arbitrary code execution. (CVE-2012-0864)

  - Multiple integer overflow conditions exist due to
    improper validation of user-supplied input when handling
    overly long strings. An unauthenticated, remote
    attacker can exploit this, via a specially crafted XML
    file, to cause a denial of service condition or the
    execution of arbitrary code. (CVE-2012-2807)

  - Multiple type-confusion errors exist in the 
    'IS_XSLT_ELEM' macro and the xsltApplyTemplates()
    function that allow a denial of service or the
    disclosure of sensitive information. (CVE-2012-2825,
    CVE-2012-2871)

  - A use-after-free error exists in the libxslt library in
    the xsltGenerateIdFunction() function that allows a
    denial of service or arbitrary code execution.
    (CVE-2012-2870)

  - Multiple format string error exist in glibc that allow
    arbitrary code execution. (CVE-2012-3404, CVE-2012-3405,
    CVE-2012-3406)

  - Multiple overflow errors exist in the glibc functions
    strtod(), strtof(), strtold(), and strtod_l() that allow
    arbitrary code execution. (CVE-2012-3480)

  - A heap-based underflow condition exists in the bundled
    libxml2 library due to incorrect parsing of strings not
    containing an expected space. A remote attacker can
    exploit this, via a specially crafted XML document, to
    cause a denial of service condition or the execution of
    arbitrary code. (CVE-2012-5134)

  - An arbitrary file modification vulnerability due to
    improper handling of certain Virtual Machine file
    descriptors. A local attacker can exploit this to read
    or modify arbitrary files. (CVE-2013-5973)");
