Synopsis

The remote VMware ESX / ESXi host is missing a security-related patch.

Description

The remote VMware ESX / ESXi host is affected by multiple vulnerabilities :

- Multiple remote code execution vulnerabilities exist in the bundled libxml2 library in the xmlXPathNextPrecedingSibling(), xmlNodePtr(), and xmlXPathNextPrecedingInternal() functions due to improper processing of namespaces and attributes nodes.
A remote attacker can exploit these, via a specially crafted XML file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2010-4008)

- Multiple remote code execution vulnerabilities exist in the bundled libxml2 library in the xmlCharEncFirstLineInt() and xmlCharEncInFunc() functions due to an off-by-one overflow condition. A remote attacker can exploit these, via a specially crafted XML file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2011-0216)

- A remote code execution vulnerability exists in the bundled libxml2 library due to improper sanitization of user-supplied input when processing an XPath nodeset. A remote attacker can exploit this, via a specially crafted request, to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2011-1944)

- A remote code execution vulnerability exists in the bundled libxml2 library in the xmlXPathCompOpEval() function due to improper processing of invalid XPath expressions. A remote attacker can exploit this, via a specially crafted XSLT stylesheet, to cause a denial of service condition or the execution of arbitrary code. (CVE-2011-2834)

- A denial of service vulnerability exists in the bundled libxml2 library due to multiple out-of-bounds read errors in parser.c that occur when getting a Stop order.
A remote attacker can exploit this, via a specially crafted XML document, to cause a denial of service condition. (CVE-2011-3905)

- A remote code execution vulnerability exists in the bundled libxml2 library in the xmlStringLenDecodeEntities() function in parser.c due to an overflow condition that occurs when copying entities. A remote attacker can exploit this, via a specially crafted request, to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2011-3919)

- A denial of service vulnerability exists in the bundled libxml2 library due to improper processing of crafted parameters. A remote attacker can exploit this to cause a hash collision, resulting in a denial of service condition. (CVE-2012-0841)

Solution

Apply the appropriate patch according to the vendor advisory that pertains to ESX version 5.0 or ESXi version 4.0 / 4.1.
