Os desenvolvedores da Mozilla lan\u00e7aram novas vers\u00f5es dos navegadores Firefox 74.0.1 e Firefox ESR 68.6.1. Os usu\u00e1rios s\u00e3o recomendados a atualizar seus navegadores, pois as vers\u00f5es lan\u00e7adas corrigem duas vulnerabilidades de dia zero que est\u00e3o sendo utilizadas por hackers na pr\u00e1tica.<\/p>\n

\"Duas<\/p>\n

As vulnerabilidades discutidas s\u00e3o CVE-2020-6819 e CVE-2020-6820, relacionadas \u00e0 maneira como o Firefox gerencia seu espa\u00e7o de mem\u00f3ria. Elas representam o que \u00e9 conhecido como vulnerabilidades de uso de mem\u00f3ria ap\u00f3s a libera\u00e7\u00e3o, permitindo que hackers insiram c\u00f3digo arbitr\u00e1rio na mem\u00f3ria do Firefox para posterior execu\u00e7\u00e3o no contexto do navegador. Esse tipo de vulnerabilidade pode ser usado para a execu\u00e7\u00e3o remota de c\u00f3digo nos dispositivos das v\u00edtimas.<\/p>\n

Informa\u00e7\u00f5es detalhadas sobre ataques reais utilizando as vulnerabilidades mencionadas n\u00e3o s\u00e3o divulgadas, o que \u00e9 uma pr\u00e1tica comum entre fornecedores de software e pesquisadores de seguran\u00e7a da informa\u00e7\u00e3o. Isso se deve ao fato de que todos eles geralmente se concentram na corre\u00e7\u00e3o r\u00e1pida dos problemas encontrados e na entrega de patches aos usu\u00e1rios, e apenas ap\u00f3s isso \u00e9 que uma investiga\u00e7\u00e3o mais detalhada sobre os ataques \u00e9 realizada.<\/p>\n

De acordo com informa\u00e7\u00f5es dispon\u00edveis, a investiga\u00e7\u00e3o sobre os ataques que utilizam essas vulnerabilidades ser\u00e1 conduzida pela Mozilla em conjunto com a empresa de seguran\u00e7a da informa\u00e7\u00e3o JMP Security e o pesquisador Francisco Alonso, que foi quem descobriu o problema. O pesquisador sugere que as vulnerabilidades corrigidas na \u00faltima atualiza\u00e7\u00e3o do Firefox podem afetar outros navegadores, embora n\u00e3o existam casos conhecidos de explora\u00e7\u00e3o de erros por hackers em diferentes navegadores.<\/p>\n
