Mozilla developers 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, Jesse Ruderman, Mats Palmgren, Carsten Book, Boris Zbarsky, David Bolter, and Randell Jesup reported memory safety problems and crashes that are fixed in Firefox ESR 45.1 and Firefox 46.
