DESCRIPTION:
Some vulnerabilities have been reported in Symantec Client Security
and Symantec AntiVirus Corporate Edition, which can be exploited by
malicious, local users to cause a DoS (Denial of Service) or gain
escalated privileges.

1) A format string error within the handling of "Tamper Protection"
and "Virus Alert Notification" messages can be exploited to execute
arbitrary code with escalated privileges by replacing the message
with a specially crafted format string.

2) Another format string error exists in the alert notification
process when displaying a notification message upon detection of a
malicious file. This can be exploited to crash the Real Time Virus
Scan service by replacing the message with a specially crafted format
string.

SOLUTION:
Apply patches (see patch matrix in vendor advisory).

PROVIDED AND/OR DISCOVERED BY:
1) David Heiland, Layered Defense.
2) Reported by the vendor
