Altiris Deployment Solution
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).

Unzip the update package and double-click on Altiris_DeploymentSolutionWin_6_9.exe.
Follow the installation instructions
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
Symantec would like to thank Brett Moore of Insomnia Security for reporting this issue and for providing full coordination while Symantec resolved it.
