CVE-2022-34484

Estado: ModificadaAlta (8.8)—

The Mozilla Fuzzing Team reported potential vulnerabilities present in Thunderbird 91.10. 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 < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
