The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-4.0.17 release! This release is a security and bug fix release resolving several issues found in the prior Squid releases. The major changes to be aware of: * SQUID-2016:10 Information disclosure in Collapsed Forwarding <http://www.squid-cache.org/Advisories/SQUID-2016_10.txt> 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. This problem is present on all 3.5 releases, though 3.5.22 is hit worst due to the collapsed revalidation extension increasing the scope of traffic which can be collapsed. * SQUID-2016:11 Information disclosure in HTTP Request processing <http://www.squid-cache.org/Advisories/SQUID-2016_11.txt> 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 vulnerability is present in all Squid-3.1 and later versions. The only known workaround is to prevent caching entirely, which is far from ideal. * TLS: Support tunneling of bumped non-HTTP traffic Previously, the use of "on_unsupported_protocol tunnel" resulted in encrypted HTTP 400 (Bad Request) messages sent to clients that do not speak HTTP(S). Such as Skype groups, which appear to use TLS-encrypted MSNP protocol instead of HTTPS. This Squid allows admins using SslBump to tunnel Skype groups and similar non-HTTP traffic bytes via "on_unsupported_protocol tunnel all". All users of Squid-4.x are urged to upgrade to this release as soon as possible. All users of Squid-3 are encouraged to test this release out and plan for upgrades where possible. See the ChangeLog for the full list of changes in this and earlier releases.
