CGI.pm is used by the Bugzilla code base. However, Bugzilla may not
always be vulnerable to issues in CGI.pm depending on they use it.

Yes, it is. However, later testing found that the issue wasn't
completely fixed in 3.50. A new patch has been developed, and is
currently pending review and acceptance by the primary CGI.pm author,
Lincoln Stein. (Now CC'ed).

Note that CGI::Simple also shares the header newline injection issue
with CGI.pm, but remains unpatched. I submitted a patch, but it has not
been applied, as seen in the Network view:
https://github.com/markstos/CGI--Simple/network
However, even the patch I submitted is not fully complete, as it mirrors
the 3.50 state of CGI.pm, and thus also needs further work. Once CGI.pm
has a final update to address the remaining header injection issue, I'll
share the same patch with CGI::Simple.
