Description
Mozilla developers reported memory safety bugs present in Firefox 70 and Firefox ESR 68.2. 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 Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
Affected configurations
• mozilla firefox (< 71.0)
• mozilla firefox esr (< 68.3)
• mozilla thunderbird (< 68.3)
• opensuse leap 15.1
