How to fix?

Upgrade squid to version 3.1.16 or higher.

Overview

Affected versions of this package are vulnerable to Resource Management Errors. The idnsGrokReply function in Squid before 3.1.16 does not properly free memory, which allows remote attackers to cause a denial of service (daemon abort) via a DNS reply containing a CNAME record that references another CNAME record that contains an empty A record.
