The remote host is vulnerable to a Denial of Service (DoS) attack.
The remote host is running Squid, a web proxy application. Versions of Squid earlier than 3.1.8 / 184.108.40.206 are potentially affected by a denial of service vulnerability caused by an internal error in its string handling. A remote attacker, exploiting this flaw, could crash the affected service.
Upgrade to Squid version 3.1.8, 220.127.116.11, or later.
