Vulnerability from variot

Squid is a powerful proxy server and web cache server. There is a logic error when receiving a very long DNS response. If a very long DNS response is returned to a Squid server that does not have an IPv6 resolver configured, an assertion error can be triggered, causing the service to crash. ----------------------------------------------------------------------
