VMSA-2011-0010 : VMware ESX third-party updates for Service Console packages glibc and dhcp

This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

The remote VMware ESX host is missing one or more security-related
patches.

Description :

a. Service Console update for DHCP

The DHCP client daemon, dhclient, does not properly sanatize
certain options in DHCP server replies. An attacker could send a
specially crafted DHCP server reply, that is saved on
the client system and evaluated by a process that assumes the
option is trusted. This could lead to arbitrary code execution
with the privileges of the evaluating process.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2011-0997 to this issue.

b. Service Console update for glibc

This patch updates the glibc package for ESX service console to
glibc-2.5-58.7602.vmw. This fixes multiple security issues in
glibc, glibc-common and nscd including possible local privilege
escalation.

The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the identifiers CVE-2010-0296, CVE-2011-0536,
CVE-2011-1095, CVE-2011-1071, CVE-2011-1658 and CVE-2011-1659 to
these issues.
