1. Summary

    ESX Service Console OS (COS) updates to remediate vulnerabilities in
    glibc and dhcp.

2. Relevant releases

    ESX 4.1 without patches ESX410-201107405-SG and
                            ESX410-201107406-SG.

3. Problem 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.

        Column 4 of the following table lists the action required to
        remediate the vulnerability in each release, if a solution is
        available.

    b. Service Console update for glibc

        This patch updates the glibc package for ESX service console to
        glibc-2.5-58.el5_6.2. 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,
