"The remote VMware ESXi 5.0 host is affected by the following
vulnerabilities :

  - 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)

  - 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)

  - 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)

  - A privilege escalation vulnerability exists due to
    improper handling of control code in the lgtosync.sys
    driver. A local attacker can exploit this escalate
    privileges on Windows-based 32-bit guest operating
    systems. (CVE-2013-3519)");
