Affected Product(s)
Product                        Version  Build   Solution(s)
Altiris Deployment Solution     6.8.x    All     6.9.164

The Symantec Altiris Deployment Server Agents are susceptible to privilege 
escalation vulnerability, commonly known as a shatter attack, which can lead 
to unauthorized privileged access. This attack is limited to users with login
access to systems running the Symantec Altiris Deployment Solution Agent 

Symantec Response
Symantec engineers have verified and resolved this vulnerability. The 
following steps are required for remediation of this security issue:

    * Goto http://www.altiris.com/download.aspx
    * Enter your email address.
    * Select "Deployment Solution for Clients 6.9" from the drop-down box
    * Click "Submit"
    * Accept the "End User License Agreement"
    * Click on "Deployment Solution for Clients 6.9" to download a zip file
        containing the Deployment Solution update.
    * Unzip the update package and double-click on 
    * Follow the installation instructions 

Best Practices
As part of normal best practices, Symantec strongly recommends:

    * Restrict access to administration or management systems to privileged 
    * Restrict remote access, if required, to trusted/authorized systems only.
    * Run under the principle of least privilege where possible to limit the
        impact of exploit by threats.
    * Keep all operating systems and applications updated with the latest 
        vendor patches.
    * Follow a multi-layered approach to security. Run both firewall and
        anti-malware applications, at a minimum, to provide multiple points of
        detection and protection to both inbound and outbound threats.
    * Deploy network and host-based intrusion detection systems to monitor 
        network traffic for signs of anomalous or suspicious activity. This 
        may aid in detection of attacks or malicious activity related to 
        exploitation of latent vulnerabilities
