Symantec LiveUpdate Administrator 2.3 and prior install some files with
insecure file permissions during a default installation. These files allow full
control permission to everyone which could result in arbitrary command
execution with elevated privileges on the system.

Affected Products
Product				Version		Solution
Symantec LiveUpdate
Administrator Windows version	2.3 and prior	Update to Symantec LiveUpdate
						Administrator Windows version
Non-Affected Products
Product				Version	
Symantec Live Update		2.3.1		

Symantec was notified of insecure file permissions following a default
installation of Symantec LiveUpdate Administrator.  Permissions on the
installed files allow full control to 'Everyone'. An authorized but
non-privileged user or an unauthorized user with access to an account on the
local system hosting Symantec LiveUpdate Administrator could potentially
leverage these improper permissions to read arbitrary system files with
elevated privileges.  There is also a potential for the unauthorized local user
to successfully overwrite arbitrary files or create scripts that execute with
SYSTEM privileges. Successful exploitation could result in an unauthorized
local user executing arbitrary commands with privileged access on the system.

Symantec Response
Symantec engineers confirmed the issue and addressed it in Symantec LiveUpdate
Administrator 2.3.1. Symantec LiveUpdate Administrator 2.3.1 is available to
customers through normal support channels.  Symantec recommends customers who
have not yet upgraded to the latest release of Symantec LiveUpdate
Administrator do so as soon as possible.

NOTE:  There are public reports suggesting that Symantec LiveUpdate
Administrator 2.3.1 does NOT fully address all of the permissions issue. 
Symantec engineers are reviewing this currently and will release an update to
LiveUpdate Administrator 2.3.1 as needed.

Symantec is not aware of any adverse customer impact from this issue.
Best Practices
As part of normal best practices, Symantec strongly recommends:

* Restrict access to administration or management systems to privileged users.
* Disable remote access or restrict it to trusted/authorized systems 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
