Products

Firefox, Firefox ESR, SeaMonkey, Thunderbird

Fixed in

• Firefox 30
• Firefox ESR 24.6

• Thunderbird 24.6

Description

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.
