Description Huzaifa S. Sidhpurwala 2016-06-06 04:07:08 UTC
Security researcher firehack reported a buffer overflow when parsing HTML5 fragments in a foreign context such as under an <svg> node. This results in a potentially exploitable crash when inserting an HTML fragment into an existing document.
