| Subject: | Symantec SGS Gateway Firewall DoS vulnerability |

Hi Group:
During Pen Testing some of my clients over the year,
those using Symantec SGS Gateway firewall, in
application proxy mode, I found vulnerable to a severe
Denial of Service issue. I spoke about this with
Symantec at a number of occasions without any
satisfying answers, suggestions or solution.
The issue is when you scan (nessus/nmap) a network
with Symantec SGS as the firewall configured in
application proxy mode, the firewall shows even
non-existent IP addresses and ports to be open and
live. This results in firewall reaching it's maximum
allowable connection limit in just 2 to 3 minutes and
network access through firewall getting choked up.
Things start working well again as you stop the scan.
I'm pretty sure this is a serious issue and Symantec
is not ready to accept it.
Any suggestions/comments?
