{"id":"CVE-2006-5633","details":"Firefox 1.5.0.7 and 2.0, and Seamonkey 1.1b, allows remote attackers to cause a denial of service (crash) by creating a range object using createRange, calling selectNode on a DocType node (DOCUMENT_TYPE_NODE), then calling createContextualFragment on the range, which triggers a null dereference.  NOTE: the original Bugtraq post mentioned that code execution was possible, but followup analysis has shown that it is only a null dereference.","modified":"2026-04-10T03:38:35.454022Z","published":"2006-10-31T22:07:00Z","references":[{"type":"ADVISORY","url":"http://www.gotfault.net/research/advisory/gadv-firefox.txt"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/450168/100/0/threaded"},{"type":"EVIDENCE","url":"http://lists.grok.org.uk/pipermail/full-disclosure/2006-October/050416.html"},{"type":"EVIDENCE","url":"http://www.gotfault.net/research/advisory/gadv-firefox.txt"},{"type":"EVIDENCE","url":"http://www.securityfocus.com/archive/1/450168/100/0/threaded"},{"type":"EVIDENCE","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=358797"},{"type":"EVIDENCE","url":"https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=213237"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/450155/100/0/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/450167/100/0/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/450682/100/200/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/452803/100/0/threaded"},{"type":"WEB","url":"http://www.securityfocus.com/bid/20799"},{"type":"WEB","url":"https://exchange.xforce.ibmcloud.com/vulnerabilities/29916"}],"schema_version":"1.7.5"}
