Description Adam Mariš 2016-02-24 14:14:23 UTC 
Due to incorrect bounds checking Squid is vulnerable to a denial of service attack when processing HTTP responses. Squid-4 is due to incorrect error handling vulnerable to a denial of service attack when processing malformed 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.
