Multiple vulnerabilities have been discovered in Request Tracker, an extensible trouble-ticket tracking system. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2012-4733 A user with the ModifyTicket right can bypass the DeleteTicket right or any custom lifecycle transition rights and thus modify ticket data without authorization. CVE-2013-3368 The rt command line tool uses semi-predictable temporary files. A malicious user can use this flaw to overwrite files with permissions of the user running the rt command line tool. CVE-2013-3369 A malicious user who is allowed to see administration pages can run arbitrary mason components , which may have negative side-effects. CVE-2013-3370 Request Tracker allows direct requests to private callback components, which could be used to exploit a Request Tracker extension or a local callback which uses the arguments passed to it insecurely. CVE-2013-3371 Request Tracker is vulnerable to cross-site scripting attacks via attachment filenames. CVE-2013-3372 Dominic Hargreaves discovered that Request Tracker is vulnerable to an HTTP header injection limited to the value of the Content-Disposition header. CVE-2013-3373 Request Tracker is vulnerable to a MIME header injection in outgoing email generated by Request Tracker. Request Tracker stock templates are resolved by this update. But any custom email templates should be updated to ensure that values interpolated into mail headers do not contain newlines. CVE-2013-3374 Request Tracker is vulnerable to limited session re-use when using the file-based session store, Apache::Session::File. However Request Tracker"s default session configuration only uses Apache::Session::File when configured for Oracle databases. This version of Request Tracker includes a database content upgrade. If you are using a dbconfig-managed database, you will be offered the choice of applying this automatically. Otherwise see the explanation in /usr/share/doc/request-tracker4/NEWS.Debian.gz for the manual steps to perform. Please note that if you run request-tracker4 under the Apache web server, you must stop and start Apache manually. The "restart" mechanism is not recommended, especially when using mod_perl or any form of persistent perl process such as FastCGI or SpeedyCGI.
