Description Huzaifa S. Sidhpurwala 2013-03-07 02:04:40 EST
VUPEN Security, via TippingPoint's Zero Day Initiative, reported a use-after-free within the HTML editor when content script is run by the document.execCommand() function while internal editor operations are occurring. This could allow for arbitrary code execution.
