The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-3.5.24 release! This release is a bug fix release resolving several issues found in the prior Squid releases. The major changes to be aware of: * Mitigate DoS attacks that use client-initiated SSL/TLS renegotiation. Recent alterations to the SSL-Bump feature logic were found to be breaking the measure put in place to disable TLS renegotiation. Since some TLSv1.2+ mechanisms actively require it and the upcoming OpenSSL v1.1+ make it quite hard to disable, we have decided to mitigate the vulnerability by implementing a rate limit on renegotiation instead of an outright disable. * SSLv2 records force SslBump bumping despite a matching step2 peek rule. This bug shows up as SSLv2 connections being bumped to deliver an error when they should have been spliced as configured. Squid will now splice all connections it has been configured to regardless of whether the obsolete SSLv2 syntax is being used. When bumping or receiving the connection itself Squid will still reject SSLv2. Only spliced traffic is affected by this. * Update External ACL helpers error handling and caching The Squid helper protocol has undergone several important changes but the external ACL logic and bundled helpers have not kept up. The ACL logics handling helper replies also had some bugs in the event of helper failures. This release fixes those various bugs and updates all the bundled helpers to make use of the BH (BrokenHelper) status to signal internal errors differently to ACL denial. * Bug #3940 pt2: Make 'cache deny' do what is documented There was a small regression in 3.5.23 release fix for bug 3940. The 'cache deny' rules were not being obeyed. Surprisingly this has had no complaints. Perhapse that is a sign that anyone using 'cache deny' rules should reasses whether those rules are still useful in these latest Squid releases. All users of Squid-3 are encouraged to upgrade to this release as soon as possible. See the ChangeLog for the full list of changes in this and earlier releases.
