In addition to Lenny's version of libcgi-pm-perl, the same issues also
affect libcgi-simple-perl, including the version currently in unstable
(1.111-1).

I'm not quite sure yet what CVE-2010-4411 refers to.  It seems that the
fix for CVE-2010-2761 was not complete, but it is not a different, new
issue?

We should probably wait until the issue is really fixed:

| 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).
