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)
