high Nessus Plugin ID 89037
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
