CVE-2010-1176
Description
Safari on Apple iPhone OS 3.1.3 for iPod touch allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to an array of long strings, an array of IMG elements with crafted strings in their SRC attributes, a TBODY element with no associated TABLE element, and certain calls to the delete operator and the cloneNode, clearAttributes, and CollectGarbage methods, possibly a related issue to CVE-2009-0075.
