You did well, but you're out of luck here. Perl-5.8.9 is the last maintenance release of the 5.8 series, so there is no further release that will contain your fix.
Since Nicholas also noted that there's no way to reliably smoke-test setuidperl (because it requires root privileges), its stableness can't be guaranteed, so it will be removed from bleadperl, unless somebody provides the means to test it reliably.
In case you found Nicholas' reply to the ticket a bit harsh, also consider that he spent much of his free time to prepare the release and with calling for real-world testing of the release candidates to prevent exactly the sort of bug you uncovered.
Nobody who used suidperl cared enough to test it before the release, now it's too late. | [reply] |
