It was a work around until Cisco fixed the code. I would keep them in there - how many times have we thought that we fixed something and then...

Hello, I inherited a Cisco 2611 that I have been trying to
clean up and understand the config on.

For a while I have been wondering why the following
were being specifically blocked...

access-list 110 deny   53 any any
access-list 110 deny   55 any any
access-list 110 deny   77 any any
access-list 110 deny   pim any any

I was doing some reading trying to learn about PIM
and found this link which references a DOS vuln.

http://securecomputing.stanford.edu/alerts/cisco-update-17jul2003.html

Was this a way to circumvent the listed vuln.?  the doc references IOS
below 12.3, as I am now above that - may I safely remove these denys?

Thanks
