We have assigned CVE-2010-0422 to the new flaw that is similar to this. https://bugzilla.redhat.com/show_bug.cgi?id=564464 https://bugzilla.gnome.org/show_bug.cgi?id=609789 There are links to the upstream commits in the gnome bug report. As with the previous issue, this one also only affects version 2.28. -- Vincent Danen / Red Hat Security Response Team
