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.
In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
Gary Kwong, Randell Jesup, Nils Ohlmeier, Jesse Ruderman, and Max Jonas Werner reported memory safety problems and crashes that affect Firefox ESR 31.2 and Firefox 33.
Christian Holler, Gary Kwong, Jon Coppeard, Eric Rahm, Byron Campen, Eric Rescorla, and Xidorn Quan reported memory safety problems and crashes that affect Firefox 33.
