RE: spp_portscan2 and UDP

[Kenton Smith <ksmith () chartwelltechnology com>]

OK, so I've got it licked; here's what I discovered. The version of the
Symantec tool I was using 1.0.1.0, which I downloaded on Saturday, said
I was not vulnerable. I went back and checked the site and they do have
a newer version 1.0.3. This version, which does a much more thorough
search, said that I was vulnerable, but not infected, interestingly
enough. I then downloaded the patch for the vulnerability only, not the
latest security roll-up, and patched the DLL's. After a reboot, this
seems to have fixed it; nothing unusual so far anyway.

Thank-you all for your suggestions and help.
