DESCRIPTION:
A vulnerability has been reported in Cisco Security Agent for
Windows, which can be exploited by malicious people to cause a DoS

buffer overflow via a specially crafted packet sent to port 139/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
