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.

ESX 4.0 without patches ESX400-201110406-SG and ESX400-201110408-SG.

ESX 3.5 without patch ESX350-201203405-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.
