Stack-based buffer overflow in Safari in Mac OS X 10.4.5 and earlier, and 10.3.9 and earlier, allows remote attackers to execute arbitrary code via unspecified vectors involving a web page with crafted JavaScript, a different vulnerability than CVE-2005-4504.

The khtml::RenderTableSection::ensureRows function in KHTMLParser in Apple Mac OS X 10.4.3 and earlier, as used by Safari and TextEdit, allows remote attackers to cause a denial of service (memory consumption and application crash) via HTML files with a large ROWSPAN attribute in a TD tag.
