The Squid HTTP Proxy team is very pleased to announce the availability of the Squid-3.5.9 release! This release is a security and bug fix release resolving issues found in the prior Squid releases. The major changes to be aware of: * SQUID-2015:3 Multiple Remote Denial of service issues in SSL/TLS processing These problems allow any trusted client or external server to perform a denial of service attack on the Squid service and all other services on the same machine. However, the bugs are exploitable only if you have configured a Squid-3.5 listening port with ssl-bump. The visible signs of these bugs are a Squid crash or high CPU usage. Skype is known to trigger the crash and/or a small amount of extra CPU use unintentionally. Malicious traffic is possible which could have severe effects. * Regression Bug 3618: ntlm_smb_lm_auth rejects correct passwords The SMB LanMan authentication helper in Squid-3.2 and later has been rejecting valid user credentials. Reminder: Use of this helper is deprecated. We strongly recommend against using it. LanMan authentication gives the illusion of transmitting NTLM protocol while actually transmitting username and password with crypto algorithms that can be decoded in real-time (this helper relies on that ability). The combination makes it overall less secure than even HTTP Basic authentication. * TLS: Support SNI on generated CONNECT after peek When Squid generates CONNECT requests it will now attempt to use the client SNI value if any is known. Note that SNI is found during an ssl_bump peek action, so will only be available on some generated CONNECT. Intercepted traffic will always begin with a raw-IP CONNECT message which must pass access controls and adaptations before ssl_bump peek is even considered. * Quieten UFS cache maintenance skipped warnings This resolves the log noise encountered since the 3.5.8 release when large caches are running a full (aka. 'DIRTY') cache_dir rebuild scan. All users of Squid are urged to upgrade to this release as soon as possible. See the ChangeLog for the full list of changes in this and earlier releases.
