Under Windows, it can also be used to steal LM/NTLM hashes.PoC: During rasterization, entities declared in the DTD are dereferenced and the content of the target file is included in the output. Command-line used: "inkscape -e xxe-inkscape.png xxe.svg" (PoC files are attached to the ticket)References: CWE-827: Improper Control of Document Type Definition http://cwe.mitre.org/data/definitions/827.htmlRegards, Nicolas GrégoireThis already has a CVE reference in the page: CVE References 2012-1102 To clarify that CVE was assigned to http://seclists.org/oss-sec/2012/q1/549 http://seclists.org/oss-sec/2012/q1/549 so this is probably an error, someone needs to tidy that bug up and post links to the source/etc so I can see whats going on.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. Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
