Comment 2 Ulrich Müller gentoo-dev 2008-11-06 06:24:53 UTC 
Sorry, I don't follow. The string "tmp" doesn't even occur in the source code:

   emacs-jabber-0.7.1 $ find . -type f | xargs grep -i tmp
   emacs-jabber-0.7.1 $

So can you please elaborate what is the problem here?
Comment 3 Christian Hoffmann (RETIRED) gentoo-dev 2008-11-06 09:12:58 UTC 
Very much looks like the problem is in Debian's build script. Can somebody confirm? We can close this as INVALID then.
Comment 4 Stefan Behte (RETIRED) gentoo-dev Security 2008-11-06 09:16:14 UTC 
There got a CVE assigned and I was copying info from rbu's bug where we collected all infos. It's a debian-specific bug. I'm sorry for wasting out time. :/
