Description Huzaifa S. Sidhpurwala 2015-08-11 06:10:10 UTC
Mozilla developers and community identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

Gary Kwong, Christian Holler, and Byron Campen reported memory safety problems and crashes that affect Firefox ESR 38.1 and Firefox 39.
