Overview
Symantecs Ghost Explorer Utility, a standalone utility tool that ships with
Symantec Ghost Solutions Suite (GSS) and Symantec Deployment Solution (DS) is
susceptible to an out-of-bounds array indexing vulnerability that could result
in an application denial of service or possibly access to unauthorized data
from adjacent arrays.
Product(s) Affected
Product Version Solution
Ghost Explorer Utility bundled with Symantec GSS All apply GSS 3.0 HF2 (12.0.0.8010)
Ghost Explorer Utility bundled with Symantec DS All apply DS 7.6 HF4 (12.0.0.7045)
NOTE: This vulnerability only impacts the optional Ghost Explorer Utility
shipped, but not installed by default, with these products. It does not allow
unauthorized access to or exposure of either GSS or DS or the underlying
operating system.
Details
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
arrays.
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
issue.
Update information
Instructions to download Symantec Ghost Explorer patch GSS 3.0 HF2,
12.0.0.8010, will be available through Symantec File Connect. DS 7.6 HF4,
12.0.0.7045, will be available through the Symantec Installation Manager for
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
users.
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
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
