Louis Dion-Marcil reports:

Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses.

This problem allows a remote server delivering certain ESI response syntax to trigger a denial of service for all clients accessing the Squid service.

Due to unrelated changes Squid-3.5 has become vulnerable to some regular ESI server responses also triggering this issue.

This problem is limited to the Squid custom ESI parser. Squid built to use libxml2 or libexpat XML parsers do not have this problem.

Due to incorrect pointer handling Squid is vulnerable to denial of service attack when processing ESI responses or downloading intermediate CA certificates.

This problem allows a remote client delivering certain HTTP requests in conjunction with certain trusted server responses to trigger a denial of service for all clients accessing the Squid service.

Squid security advisory 2016:10 reports:

Due to incorrect comparison of request headers Squid can deliver responses containing private data to clients it should not have reached.

This problem allows a remote attacker to discover private and sensitive information about another clients browsing session. Potentially including credentials which allow access to further sensitive resources. This problem only affects Squid configured to use the Collapsed Forwarding feature. It is of particular importance for HTTPS reverse-proxy sites with Collapsed Forwarding.

Due to incorrect HTTP conditional request handling Squid can deliver responses containing private data to clients it should not have reached.

This problem allows a remote attacker to discover private and sensitive information about another clients browsing session. Potentially including credentials which allow access to further sensitive resources..
