Description Doran Moppert 2017-08-08 06:36:02 UTC 
Mozilla developers and community members Masayuki Nakano, Gary Kwong, Ronald Crane, Andrew McCreight, Tyson Smith, Bevis Tseng, Christian Holler, Bryce Van Dyk, Dragana Damjanovic, Kartikaya Gupta, Philipp, and Tristan Bourvon reported memory safety bugs present in Firefox 54 and Firefox ESR 52.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code.
