Package: perl
Version: 5.12.3-6
Severity: important

After the upgrade to perl 5.12, a file creation in a suid Perl script
no longer works. AFAIK the perl upgrade isn't supposed to introduce
backward incompatible changes (at least nothing was announced).

My script is the following:

-rwsr-sr-x 1 news news 5535 2006-03-10 13:25:34 /usr/local/bin/rpnews

It contains:

#!/usr/bin/perl -T

[...]

$< = $>;  # set real to effective uid

$ENV{'PATH'} = '/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin';

my $news = '/var/spool/news';
my $lock = "$news/rpnews.lock";

open LOCK, ">$lock" or die "$proc: can't create lock file\n$!\n";

and when running it as a normal user, I get the error:

rpnews: can't create lock file
Permission denied
zsh: exit 13    rpnews
