Symantecs Ghost Explorer Utility, a standalone utility tool that ships with 
Symantec Ghost Solutions Suite (GSS) and Symantec Deployment Solution (DS) is

Product							Version		Solution

Ghost Explorer Utility bundled with Symantec GSS	All		apply GSS 3.0 HF2 (

Ghost Explorer Utility bundled with Symantec DS		All		apply DS 7.6 HF4 (

unauthorized access to or exposure of either GSS or DS or the underlying 
operating system.


Symantec Ghost Explorer, ghostexp.exe, is a stand-alone utility tool that 
ships with the Symantec Ghost Solution Suite and Symantec Deployment Solution
as an option that can be installed separately if required. The Symantec Ghost
Explorer utility is used to view the contents of a ghost image file. The 
utility provides addition or deletion of files to or from a ghost image file.
Symantec Ghost Explorer can be invoked from the using application in the case
of DS if installed, or run as a stand-alone tool by users who have chosen to 
install it.

Symantec was notified of an out-of-bounds array indexing issue in the Ghost 
Explorer utility byte arrays as a result of insufficient boundary checks. This
failure to properly terminate indexing could potentially result in the 
application crashing or possibly allow unauthorized access to data in adjacent

Symantec Response

Symantec engineers verified the reported issue and have released updates for 
both versions of the utility, the version shipping with GSS 3.0 and the 
version shipping with DS 7.6.

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

Update information

Symantec IT Management System (ITMS).

Best Practices

As part of normal best practices, Symantec h3ly recommends:

Restrict access to administration or management systems to privileged 

Disable remote access if not required or restrict it to trusted/authorized
systems only.

Where possible, limit exposure of application and web interfaces to 
trusted/internal networks only.

Keep all operating systems and applications updated with the latest vendor

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
