correcting the following security flaws:
=======================================

The previously released tool to upgrade weak password hashes as part of CVE-2011-0009 was an incomplete fix and failed to upgrade passwords of disabled users. This release includes an updated version of the vulnerable-passwords tool, which should be run again to upgrade the remaining password hashes. CVE-2011-2082 is assigned to this vulnerability.

RT versions 3.0 and above contain a number of cross-site scripting (XSS) vulnerabilities which allow an attacker to run JavaScript with the user's credentials. CVE-2011-2083 is assigned to this vulnerability.

RT versions 3.0 and above are vulnerable to multiple information disclosure vulnerabilities. This includes the ability for privileged users to expose users' previous password hashes -- this vulnerability is particularly dangerous given RT's weak hashing previous to the fix in CVE-2011-0009. A separate vulnerability allows privileged users to obtain correspondence history for any ticket in RT. CVE-2011-2084 is assigned to this vulnerability.

All publicly released versions of RT are vulnerable to cross-site request forgery (CSRF), in which a malicious website causes the browser to make a request to RT as the currently logged in user. This attack vector could be used for information disclosure, privilege escalation, and arbitrary execution of code. Because some external integrations may rely on RT's previously permissive functionality, we have included a configuration option ($RestrictReferrer) to disable CSRF protection. We have also added an additional configuration parameter ($ReferrerWhitelist) to aid in exempting certain originating sites from CSRF protections. CVE-2011-2085 is assigned to this vulnerability.

We have also added a separate configuration option ($RestrictLoginReferrer) to prevent login CSRF, a different class of CSRF attack where the user is silently logged in using the attacker's credentials. $RestrictLoginReferrer defaults to disabled, because this functionality's benign usage is more commonly relied upon and presents less of a threat vector for RT than many other types of online applications.

RT versions 3.6.1 and above are vulnerable to a remote execution of code vulnerability if the optional VERP configuration options ($VERPPrefix and $VERPDomain) are enabled. RT 3.8.0 and higher are vulnerable to a limited remote execution of code which can be leveraged for privilege escalation. RT 4.0.0 and above contain a vulnerability in the global $DisallowExecuteCode option, allowing sufficiently privileged users to still execute code even if RT was configured to not allow it. CVE-2011-4458 is assigned to this set of vulnerabilities.

RT versions 3.0 and above may, under some circumstances, still respect rights that a user only has by way of a currently-disabled group. CVE-2011-4459 is assigned to this vulnerability.

RT versions 2.0 and above are vulnerable to a SQL injection attack, which allow privileged users to obtain arbitrary information from the database. CVE-2011-4460 is assigned to this vulnerability.
