That's correct. CVE-2012-1102 has been assigned to the perl XML-Atom issue. Assuming the source of the slight confusion is this comment: https://bugs.launchpad.net/inkscape/+bug/1025185/comments/13 and the CVE id in the references. But from the context of that bug, comment c#13 was used just to reference patch for same issue in perl XML-Atom (CVE-2012-1102) issue, when searching a patch for inkscape. Which later resulted into upstream inkscape commit: http://bazaar.launchpad.net/~inkscape.dev/inkscape/trunk/revision/11931 referenced in (subsequent) comment c#14: https://bugs.launchpad.net/inkscape/+bug/1025185/comments/14 So CVE-2012-1102 identifier is for perl XML-Atom problem. And this (same XXE problem) being present in inkscape should get a new CVE id yet.
