Altiris Deployment Solution 6.8.xAll6.9.164


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 (AClient.exe).

Symantec Response

Symantec engineers have verified and resolved this vulnerability. The following steps are required for remediation of this security issue:
  • 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 Altiris_DeploymentSolutionWin_6_9.exe.

Best Practices

As part of normal best practices, Symantec strongly recommends:
  • Restrict access to administration or management systems to privileged users.
  • 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
