Note that the koffice release notes include the following:

KPresenter Import Filter for PowerPoint

    * There is a security issue in the import filter for MS Powerpoint, that is
fixed with this release. Every KOffice user should upgrade to 1.6.1 for this
reason alone.

so this update has security implications.  I can find no CVE at this time.

yucky, I'm working on the koffice-1.6.1 update, I'll try to expedite things.

So far, so good, devel(fc7) branch build (almost) done:
http://buildsys.fedoraproject.org/build-status/job.psp?uid=22760

Queue'd builds for 
koffice/FC-5 (job id: 22771)
koffice/FC-6 (job id: 22772)
koffice-langpacks/devel (job id 22773)
then shortly after buildsys went awol.  ??  

Will recheck buildsys status later tonight, or tomorrow morning.

All done.

The security issue is CVE-2006-6120.  For the record, FC-4 (koffice 1.6.0) is
still most likely vulnerable.

OK, we can do FC-4 too, reopening...

koffice-1.6.1-1.fc4 build queue'd (job id 23038)
