Description of problem: rt3 <= 3.6.6 is vulnerable to a DoS attack thru the perl-Devel-StackTrace < 1.19 vector. Both the perl module and rt 3.6.7 are needed to fully fix the security issue. See http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3502 and http://lists.bestpractical.com/pipermail/rt-announce/2008-June/000158.html for details.
Actually, upstream announcement is worded bit differently: Installing this newer version of the module is a complete fix, and will close the vulnerability. New RT only seems to have additional protections for possible (but currently unknown) similar issue. perl-Devel-StackTrace 1.20 that should fix this is already in all Fedora versions.

This interpretation matches with mine. Independently, I've pushed rt3-3.6.7 to fc9/testing, because it already had been part of "devel"/rawhide for some time during FC10 development, but had never made it into "stable". Whether I'll push this package to FC9/stable is a different matters. My problem: I don't have access to an FC9 anymore.
rt3-3.6.7-1.fc9 has been pushed to the Fedora 9 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing-newkey update rt3'.

This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
