Amos Jeffries reports:

-
The proxy contains a String object class with 64KB content limits. - Some code paths do not bounds check before appending to these - String and overflow leads to an assertion which terminates all - client transactions using the proxy, including those unrelated to - the limit being exceeded.

Error handling for malformed HTTP responses can lead to a second - assertion with the same effects as the first issue.

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.
