"Best Practical reports :

RT 4.2.0 and above may be vulnerable to arbitrary execution of code by
way of CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277, or
CVE-2014-6271 -- collectively known as 'Shellshock.' This
vulnerability requires a privileged user with access to an RT instance
running with SMIME integration enabled; it applies to both mod_perl
and fastcgi deployments. If you have already taken upgrades to bash to
resolve 'Shellshock,' you are protected from this vulnerability in RT,
and there is no need to apply this patch. This vulnerability has been
assigned CVE-2014-7227.");
