This announcement upgrades Squid from 2.5STABLE5 to 2.5STABLE9 in order to fix bug #13718[2] and also fixes the two following vulnerabilities: 1.Unexpected access control results on configuration errors[3] On configuration errors involving wrongly defined or missing acls the http_access results may be different than expected, possibly allowing more access than intended. This patch makes such configuration errors a fatal error, preventing the service from starting until the access control configuration errors have been corrected. 2.Race condition related to Set-Cookie header[4] A race window has been discovered where Set-Cookie headers may leak to another users if the requested server relies on the old (obsolete since 1997) Netscape Set-Cookie specifications in how caches should handle the Set-Cookie header on otherwise cacheable content. SOLUTION It is recommended that all squid users upgrade to the latest packages. This update will automatically restart the service if it is already running.
