**Nome do software vulnerável e versões afetadas** Versões do Firefox anteriores à 73 Versões do Firefox ESR anteriores à 68.5 Versões do Thunderbird anteriores à 68.5 **Descrição** O problema está relacionado a falhas de segurança de memória que podem causar corrupção de memória. Presume-se que essas falhas possam ser exploradas para executar código arbitrário com esforço suficiente. Essas falhas são potencialmente arriscadas em navegadores ou contextos semelhantes a navegadores, mas não podem ser exploradas por e-mail no produto Thunderbird devido à desativação de scripts durante a leitura de e-mails. **Recomendações** Para versões do Firefox anteriores à 73, atualize para a versão 73 ou posterior. Para versões do Firefox ESR anteriores à 68.5, atualize para a versão 68.5 ou posterior. Para versões do Thunderbird anteriores à 68.5, atualize para a versão 68.5 ou posterior.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 68 **Description** The issue is related to memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. It is also described as a buffer data boundary operation vulnerability, where exploitation could allow a remote attacker to execute arbitrary code. **Recommendations** For versions prior to 68, update to version 68 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive data and minimizing browser usage until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 63 Firefox ESR versions prior to 60.3 Thunderbird versions prior to 60.3 **Description** The issue is caused by memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code with enough effort. It is also described as a buffer overflow in memory, allowing a remote attacker to execute arbitrary code. **Recommendations** For Firefox versions prior to 63, update to version 63 or later. For Firefox ESR versions prior to 60.3, update to version 60.3 or later. For Thunderbird versions prior to 60.3, update to version 60.3 or later.
