DESCRIPTION:
A vulnerability has been reported in Cisco Security Agent for
Windows, which can be exploited by malicious people to cause a DoS
(Denial of Service) or compromise a vulnerable system.

The vulnerability is caused due to a boundary error in an unspecified
system driver used by the application and can be exploited to cause a
buffer overflow via a specially crafted packet sent to port 139/TCP
or 445/TCP.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in all versions of Cisco Security Agent
for Windows (managed or unmanaged). Please see the vendor's advisory
