Sam, could you please forward you incoming mail about security issues to
someone who has more time to look into it?

This wasn't reported in the Debian BTS.

True, a reported and meanwhile fixed bug.

I (the person uploading that version) was not aware of this, partly
because you didn't file a bug in the BTS about this. Note however that
the upstream changelog does mention:
- Fixed XSS vulnarability in content-type display in the attachment
area of read_body.php discovered by Roman Medina.
Since I didn't realize these issues might still also be in the 1.5.0
package, I didn't separately mention that in the Debian changelog, nor
set urgency to high (and make more haste with the upload...)

Thanks for the direct pointer, I assume you did contact
firstname.lastname@example.org about this?
Also, statements like this won't help you very much if you want a

But Debian unstable keeps getting lots of other bugs, so is often no
If Debian isn't notified of security bugs, they can't fix them. Weird
that you here claim unstable was free of these bugs, while above you
claim Debian unstable _had_ these bugs at the time of your advisory. So,
which one of the two is it? Or are there more issues involved than the
ones detailed in RS-2004-1?

My constructive tips in return are:
- once security bugs are made public, file them in the Debian BTS with
tag security and (if only in woody) tag woody, and severity serious
(for RS-2004-1, I'll do so myself in a minute)
- Draw Debian QA's attention via email@example.com (public
mailinglist) to it if it doesn't seem to get fixed in a timely matter
or there is no maintainer response at all, and/or the security team's
attention if this vulnerability is still unfixed in woody)
- If they are not yet public, contact the Debian security team with
precise references and possibly patches/fixes
- Since I'm a PHP developer and use squirrelmail too, you might also in
this case try to mail me these specific details if you believe
squirrelmail in woody is still vulnerable of some issues.
- Refrain from flamebait if you're not interested in a flame-war ;-)
