Mozilla Developers

Impact

Critical

Products

Firefox, Firefox ESR, Thunderbird

Fixed in

• Firefox 45
• Firefox ESR 38.7
• Thunderbird 38.7
• Thunderbird 45

Description

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.
