Fix is included in upstream gd version 2.0.34.  Versions of gd currently shipped
in Fedora are not affected.

Related issue affecting other packages that use derivate of the same GIF
handling code: CVE-2007-6697 (SDL_image), CVE-2008-0553 (tk), CVE-2008-0554 (netpbm)

graphviz includes and seems to use local copy of gd code.  I haven't
investigated whether graphiz has any way to load GIF images, so I can't tell if
it's really affected by this problem.  Patrick, Alex, any thoughts?  Can graphiz
packages be modified to use system gd library instead of local copy?

If graphviz is affected, only F7 version (2.12) needs to be fixed, as it ships
with embedded gd 2.0.33.  F8 version (2.14.1) embeds fixed gd 2.0.34.

Actually, I'm pretty sure the version of graphviz-gd in F8 uses the system gd,
or so the package's dependency on libgd.so.2 would suggest to me.

So what I would immediately consider is pushing 2.14.1 to F7.  Any objections to
that?

Cc'ing John Ellson (graphviz upstream) and Debarshi Ray (graphviz downstream,
anjuta maintainer).  Debarshi, anjuta will need a rebuild if I bump graphviz. 
Just a heads-up.

Thanks for clarification.  I haven't investigated F8 version closely once I've
notices gd version there is fixed.  I've seen gd being build on F7 (according to
build.log from latest F7 package).

If rebase is not practical, patch linked in the initial comment (in PHP CVS
repo) should trivial to adjust for graphviz.

Your risk is causing problems with anjuta and doxygen by going from 2.12 to 2.14

Graphviz is happy with a system gd >= 2.0.34, and fc7 has 2.0.35, so a more
conservative change would be to just rebuild graphviz-2.12.

Check that --with-mylibgd is *not* set in the spec file


The upstream sources already contain this patch, for anyone using graphviz on
systems with older versions of gd.

Thank you for the heads up.

In fact the Anjuta package and a few of its dependencies -- libgdl (formerly
anjuta-gdl), gnome-build and autogen -- in Fedora are seriously outdated. I
inherited some of them sometime ago (yet to get autogen), and am gradually
freshening them up. I am going to submit a fresh Anjuta package for F-7, F-8 and
Rawhide sometime soon, so the re-builds will anyway happen one way or the other.

graphviz-2.12-10.fc7 has been submitted as an update for Fedora 7

graphviz-2.12-10.fc7 has been pushed to the Fedora 7 stable repository.  If problems still persist, please make note of it in this bug report.
