Description Huzaifa S. Sidhpurwala 2011-11-08 04:36:22 UTC

A vulnerability where Firefox/Thunderbird uses memory not initialized could allow remote execution using a crafted web.
Doing a bad nesting with especially li, ul, dd and a bad tag and also using some css properties, Firefox/Thunderbird got 
crashed in an exploitable way.
