The squid patches page notes :
A malicious gopher server may return a response with very long lines
that cause a buffer overflow in Squid.
Workaround: Since gopher is very obscure these days, do not allow
Squid to any gopher servers. Use an ACL rule like : acl Gopher proto
gopher http_access deny Gopher
