Bugzilla Bug 194713

According to
http://lists.gnu.org/archive/html/emacs-devel/2007-10/msg00132.html there might
be a "temp file hole" in Emacs functions tramp-make-temp-file and
tramp-make-tramp-temp-file.

Affected ebuilds:

   =app-editors/emacs-cvs-22.1.50_p20070829 (CVS snapshot)
   =app-editors/emacs-cvs-23.0.0-r7 (live CVS, hardmasked)
   =app-editors/emacs-cvs-23.0.50 (live CVS)
   =app-emacs/tramp-2.1.10-r1 (stable)

I have verified that app-editors/emacs and <app-emacs/tramp-2.1 are _not_
affected by the problem.

 Can be masked, we want it in the tree as reference because shortly after big
changes were introduced into upstream's tree.  Patch it?

 Will regulate itself by upstream, we can do a revision bump to force users to
upgrade.

>    =app-emacs/tramp-2.1.10-r1 (stable)

 Will be patched by us.

 And you even filed it faster than me! 

Here I propose B3 as severity, because confidential information can leak.

Upstream has committed a patch to their CVS, and I have backported it to
app-emacs/tramp-2.1.10 and app-editors/emacs-cvs-22.1.50_p20070829.

I still have to do some more testing, but I hope I can commit new ebuilds for
both this evening.

Current status:

=app-editors/emacs-cvs-22.1.50_p20070829
   fixed in -r1

=app-editors/emacs-cvs-23.0.0-r7
   live CVS, not yet fixed, hardmasked

=app-editors/emacs-cvs-23.0.50
   live CVS, was fixed by upstream
   security team: asking you for advice, is a revbump needed here?

=app-emacs/tramp-2.1.10-r1
   fixed in -r2


Arch teams: Please stabilise app-emacs/tramp-2.1.10-r2
Test plan: <http://overlays.gentoo.org/proj/emacs/wiki/test%20plans>

ppc stable

x86 stable

alpha/sparc stable

amd64 stable

app-emacs/tramp-2.1.10-r1 removed.
Everything fixed (or hardmasked) now.

Your typical insecure temp file creation bug, I vote yes for GLSA.

voting yes too, and request filed.

Vulnerable versions:
app-emacs-tramp   <2.1.10-r2

Unaffected versions:
app-emacs/tramp   <2.1, >=2.1.10-r2

app-editors/emacs-cvs never had any stable version.

GLSA 200710-22

Just to be explicit about this: app-xemacs/tramp-1.37 is based on tramp 2.0.55
and thus not affected by this bug. When a new version of app-xemacs/tramp is
generated upstream we (=xemacs herd) should check that this is not based on a
version that has this issue.
