Altiris Deployment Solution 6.8.x All 6.9.164
Details
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:
* 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
Altiris_DeploymentSolutionWin_6_9.exe.
* Follow the installation instructions
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
