Description
Memory safety bugs present in Firefox 133, Thunderbird 133, Firefox ESR 128.5, and Thunderbird 128.5. 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 was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6.
Affected configurations
• mozilla firefox (< 128.6.0)
• mozilla firefox (< 133.0)
• mozilla thunderbird (< 128.6.0)
• mozilla thunderbird (>= 129.0 < 134.0)
