Description

Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR 68.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.

Affected configurations

• mozilla firefox (< 76.0) • mozilla firefox esr (< 68.8.0) • mozilla thunderbird (< 68.8.0) • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 19.10 • canonical ubuntu linux 20.04
