The remote FreeBSD host is missing a security-related update.
Squid security advisory 2015:2 reports :
Squid configured with cache_peer and operating on explicit proxy
traffic does not correctly handle CONNECT method peer responses.
The bug is important because it allows remote clients to bypass
security in an explicit gateway proxy.
However, the bug is exploitable only if you have configured cache_peer
to receive CONNECT requests.
