Exploit Publicly Available: No

Overview

An arbitrary memory overwrite vulnerability exists in a Symantec Deployment 
Solution agent allowing a local and authorized malicious user to potentially 
elevate privileges on the local system. This vulnerability applies to Windows
XP (SP3) or Windows Server 2003 (SP2) only.

Affected Products

Product				Version		Build		Solution(s)

Symantec Deployment Solution	6.9 and prior	All		Use DAgent and disable use of AClient 
								(See mitigation URL below for more 
								information)

Details

A Symantec Deployment Solution agent driver, AClient, is susceptible to a 
buffer overflow resulting from a malicious user with local access being able 
to potentially overwrite memory, possibly resulting in an escalation of 
privilege on the system.

NOTE: This issue can only be exploited on Windows XP and Windows Server 2003 
as newer Windows operating systems have different verification methodologies 
and so are not impacted by this issue.

Successful exploitation could potentially allow a local user to gain 
unauthorized access to resources on the targeted system, interfere with 
communications between the client and server or, disrupt or modify the 
capability of the management server to effectively monitor and manage the 
client system.

Symantec Response

Symantec engineers have reviewed and validated this issue as impacting 
versions of Deployment Solution 6.9 on Windows XP and Windows Server 2003 
only.

Symantec recommends customers disable use of Deployment Solution 6.9 AClient 
and enable the DAgent.

Symantec is not aware of exploitation of or adverse customer impact from this
issue.

Mitigation Information

Please refer to Knowledge Base article, DOC7993, Arbitrary Write Privilege 
Escalation in Altiris AClient agent for more information.

Best Practices

As part of normal best practices, Symantec strongly recommends that customers:

      * Restrict access of 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
