Security bug in mahara-1.0.4-3: upload to testing-proposed-updates?

[Francois Marier <francois@debian.org>]

(Please CC me on your replies, thanks!)

Hello,

The version of mahara that's in lenny (1.0.4-3) has an XSS vulnerability as
reported in the release notes:

  http://mahara.org/interaction/forum/topic.php?id=198

(no Debian bug or CVE number for it at the moment)

There is a new upstream release (1.0.9) containing these fixes in
sid. However, given that it contains other non-security changes, I have also
prepared a patched 1.0.4 version for lenny.

I have attached the very small debdiff between -3 and -4 to this email.

Please let me know whether I should upload 1.0.4-4 to
testing-proposed-updates or whether you prefer to unblock the package that's
in sid.

Cheers,
Francois
