Squid security advisory 2016:2 reports:

Due to incorrect bounds checking Squid is vulnerable to a denial of service attack when processing HTTP responses.

These problems allow remote servers delivering certain unusual HTTP response syntax to trigger a denial of service for all clients accessing the Squid service.

HTTP responses containing malformed headers that trigger this issue are becoming common. We are not certain at this time if that is a sign of malware or just broken server scripting.
