Description Stefan Cornelius 2012-03-19 10:57:28 UTC

The original fix for CVE-2012-0248 was found to be insufficient.

The original fix for CVE-2012-0248 failed to correct the denial of service condition in "profile.c" source code part, too. This still allowed the specially-crafted image file, when processed for example by the "convert" executable, to cause original CVE-2012-0248 problem (denial of service).

Relevant upstream patch:
[1] http://trac.imagemagick.org/changeset/6998/ImageMagick/branches/ImageMagick-6.7.5/magick/profile.c

Comment 2 Pavel Alexeev 2012-03-19 19:58:29 UTC

Is upstream author informed about it?

Comment 3 Stefan Cornelius 2012-03-19 20:17:51 UTC

> Is upstream author informed about it?


Yes, they've been informed about the issues and published fixes (e.g. see the patches linked in the description above - comment #0).

Comment 4 Pavel Alexeev 2012-03-20 16:29:04 UTC

I meant is author informed what they patch is not sufficient?

And is there already complete solution?

Comment 5 Stefan Cornelius 2012-03-20 18:05:03 UTC

Pavel,

Yes, we've informed ImageMagick upstream about the incorrect fix, so ImageMagick upstream knows about the incorrect fix. Upstream ImageMagick has completely fixed this in the ImageMagick subversion repository (3 weeks ago).

If you want to know a detailed list of the upstream ImageMagick releases including the complete fix, you should contact ImageMagick upstream.

Comment 6 Pavel Alexeev 2012-04-11 13:29:24 UTC

Rawhide build which should fix it http://koji.fedoraproject.org/koji/taskinfo?taskID=3977291.

Comment 7 Stefan Cornelius 2012-04-24 21:38:05 UTC

Statement:

Not vulnerable. This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 5 and 6 as they did not backport the insufficient patch for CVE-2012-0248.
