squid -- buffer overflow vulnerability in gopherToHTML

Description:

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
