CVE-2004-1617: Input Validation
First published: Mon Oct 18 2004(Updated: )
Lynx, lynx-ssl, and lynx-cur before 2.8.6dev.8 allow remote attackers to cause a denial of service (infinite loop) via a web page or HTML email that contains invalid HTML including (1) a TEXTAREA tag with a large COLS value and (2) a large tag name in an element that is not terminated, as demonstrated by mangleme. NOTE: a followup suggests that the relevant trigger for this issue is the large COLS value.
