Description Huzaifa S. Sidhpurwala 2016-06-06 04:08:27 UTC 
Security researcher firehack used the Address Sanitizer tool to discover a use-after-free in contenteditable mode. This occurs when deleting document object model (DOM) table elements created within the editor and results in a potentially exploitable crash.
