Comment 3 Matthias Geerdsen (RETIRED) gentoo-dev 2004-12-12 11:58:30 UTC
according to the patch mentioned in comment #2 is going into 0.37

the zwiki repository already includes it, see
and for the diff:**20041130080308-e02d6-1004ac472bd9fb2924af6ec6ca708b33c5e18f6b.gz

net-zope: since 0.37 is overdue already, you should consider adding this relatively simple patch into a new revision
Comment 4 Matthias Geerdsen (RETIRED) gentoo-dev 2004-12-18 14:08:06 UTC
net-zope, this bug is open for quite a while now, pls comment
Comment 5 Jodok Batlogg (RETIRED) gentoo-dev 2004-12-18 14:22:58 UTC
revision bump to 0.36.2, checked in ~x86
Comment 6 Luke Macken (RETIRED) gentoo-dev 2004-12-18 16:14:57 UTC
This issue is not fixed in 0.36.2.

net-zope, please either apply patch or wait for 0.37 which is coming out "any day now".
Comment 7 Jodok Batlogg (RETIRED) gentoo-dev 2004-12-19 09:01:14 UTC
we'll wait for the new release
Comment 8 Radoslaw Stachowiak (RETIRED) gentoo-dev 2004-12-20 07:58:37 UTC
fixed as version 0.36.2-r1.
will be marked stable in a few hours, please report back in case of problems.
Comment 9 Matthias Geerdsen (RETIRED) gentoo-dev 2004-12-20 09:45:48 UTC
Thanks Radoslaw :)

(note: only needs x86 stable marking, otherwise it's just ~ppc and didn't have a stable version there before)
Comment 10 Radoslaw Stachowiak (RETIRED) gentoo-dev 2004-12-20 23:51:10 UTC
commited into portage as stable x86.
Comment 11 Chris White (RETIRED) gentoo-dev 2004-12-21 00:02:44 UTC
Not FIXED until glsa is released...
Comment 12 Matthias Geerdsen (RETIRED) gentoo-dev 2004-12-21 00:31:09 UTC
security, pls vote on GLSA
Comment 13 Thierry Carrez (RETIRED) gentoo-dev 2004-12-21 01:20:06 UTC
Hmm... I would tend to say "yes", as zwiki in a CMS, like wordpress or others we've issues advisories for.
Comment 14 Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2004-12-21 03:34:22 UTC
Initially I would tend to say no, but with Koon's arguments I tend to say yes.
Comment 15 Matthias Geerdsen (RETIRED) gentoo-dev 2004-12-21 08:05:23 UTC

that's three times a "yes" -> GLSA
