Comment 2 Kevin Kofler 2015-12-10 08:27:41 UTC

I'm looking into fixing this in Fedora, looks like the upstream fix should be straightforward to backport.

Comment 3 Kevin Kofler 2015-12-10 08:30:55 UTC

The arts version of the code is in mcop/mcoputils.cpp.

Comment 4 Kevin Kofler 2015-12-10 08:31:26 UTC

Small correction: The arts version of the code is in mcop/mcoputils.cc.

Comment 5 Kevin Kofler 2015-12-10 08:40:03 UTC

We also need to remove this hack:
http://pkgs.fedoraproject.org/cgit/arts.git/tree/arts-1.5.0-check_tmp_dir.patch
which was a quick fix for bug #169631 (failure to run if lnusertemp is not found on the system), but this has since been fixed upstream by a copy&paste of the lnusertemp code (the code we need to fix here) and is thus not needed anymore, and now the check_tmp_dir patch interferes with the security fix.

Comment 6 Kevin Kofler 2015-12-10 09:03:02 UTC

This should fix it:
http://pkgs.fedoraproject.org/cgit/arts.git/plain/arts-1.5.10-CVE-2015-7543.patch

Building for Rawhide now, I will issue updates for releases if it builds.

Comment 7 Kevin Kofler 2015-12-10 09:20:09 UTC

This built fine for Rawhide. Updates for releases are coming ASAP (probably later today).
