[squid-users] Security Concerns

I am running Squid on a Linux box which is also hosting a customer
database (Oracle).

I am concerned that by having the Proxy server on the same box as the
database that I am introducing an increased security risk.

e.g. an exploit in squid might mean that a hacker is able to gain access
to my customer database.

Assuming that my network is locked down so that the (external router)
firewall has blocked all WAN->LAN traffic to our network on all ports am
I correct in assuming that....

The only weakness is from an security exploit to squid being initiated
from inside our network.

The network user might potentially be duped to go to a boobytrapped web
page which has the potential to exploit a security weakness in squid itself.

Thanks in advance for your answers, I would like to be able to sleep
soundly that my proxy server is not a security risk to my data.
