Description Raphael Marichez (Falco) (RETIRED) gentoo-dev 2008-02-01 17:58:47 UTC

a similar problem to bug 207933 (CVE-2006-4484) has been found in Tk, but it's not public yet. (it should be public today, but i've seen no public advisory yet).

Maintainers, please do not commit anything yet, but you might want to test this patch now, since it'll probably be public in a matter of hours.

in cvs.
plz mark stable tk-8.4.15-r2

Public now, it's SA28784 and CVE-2008-0553

If you know about other packages actually using a vulnerable embedded code, please let us know.
Comment 4 Steve Arnold archtester gentoo-dev 2008-02-10 22:40:06 UTC
Sourcenav patched (both versions).
Comment 5 Raphael Marichez (Falco) (RETIRED) gentoo-dev 2008-02-11 20:39:35 UTC

the patch is official in tk 8.5.1, you (maintainers) can include it in your ebuilds so that i can call arches one time for all these packages, and we can avoid splitting this bug into several bugs and several glsas.

Comment 6 Robert Buchholz (RETIRED) gentoo-dev 2008-02-11 23:50:54 UTC
A copy of the code is also shipped by:
* sci-astronomy/ds9
* sci-visualization/paraview
* games-util/umodpack
* media-sound/rat
* sys-devel/gcc-nios2
* sys-devel/binutils-nios2

I did not check whether the code is actually used yet, hopefully someone else can.
Comment 7 Raphael Marichez (Falco) (RETIRED) gentoo-dev 2008-02-14 15:55:22 UTC
Thanks rbu, i performed further checks. Since there are numerous affected ebuilds, if maintainers don't manifest in a reasonable time (1 week), i'll add the patch to the ebuilds myself.

dev-lang/tk compiles the vulnerable code.

dev-util/sourcenav compiles it

dev-util/insight compiles it

dev-perl/perl-tk compiles it

* sci-astronomy/ds9 compiles it

* sci-visualization/paraview only in 2.x . Not in 3.x. Latest version unaffected --> not a problem, just remove 2.x or patch 2.x

* games-util/umodpack uses it as a dependency but does not ship it

* media-sound/rat only in the latest version (3.x). No stable ebuild affected. Not sure it actually uses the code. We'll suppose so. 3.x has to be patched.

* sys-devel/gcc-nios2 didn't try to compile, but code is here

* sys-devel/binutils-nios2 didn't try to compile, but code is here
Comment 8 Raphael Marichez (Falco) (RETIRED) gentoo-dev 2008-02-14 16:13:59 UTC
I would also like to know whether an attacker can control the GIF images that would be opened by the Tk component of the applications. If the attacker cannot entice a user to open a specially crafted GIF image with the Tk library, there is no vulnerability in your package. I don't know the mentioned package enough to say, so i need maintainers' help.

Fixed in portage cvs via patch.

perl-tk done, vulnerable ebuild removed.

If I see it correctly we are done here, right?

Almost. It's GLSA time.

These aren't in the tree anymore.  Removing toolchain
