Os desenvolvedores do projeto GNOME lan\u00e7aram uma atualiza\u00e7\u00e3o para o aplicativo de ajuda Yelp, corrigindo uma vulnerabilidade que permitia a sa\u00edda do ambiente sandbox do Flatpak.<\/p>\n

O problema estava relacionado ao processamento de URIs externos e \u00e0s particularidades da integra\u00e7\u00e3o do Yelp com os mecanismos de inicializa\u00e7\u00e3o de aplicativos. Ao abrir um documento especialmente preparado, um atacante poderia executar comandos fora das restri\u00e7\u00f5es do sandbox, obtendo acesso ao sistema do usu\u00e1rio com privil\u00e9gios do usu\u00e1rio atual.<\/p>\n

A vulnerabilidade afetava principalmente cen\u00e1rios em que o Yelp era usado dentro de aplicativos Flatpak ou fornecido como parte de um ambiente sandbox. A capacidade de explora\u00e7\u00e3o remota dependia de conseguir convencer o usu\u00e1rio a abrir um arquivo de ajuda malicioso ou um link.<\/p>\n

A corre\u00e7\u00e3o j\u00e1 foi inclu\u00edda nas novas vers\u00f5es do Yelp e come\u00e7a a aparecer nos pacotes das distribui\u00e7\u00f5es. Os desenvolvedores do GNOME tamb\u00e9m refor\u00e7aram as verifica\u00e7\u00f5es de URI e restringiram as maneiras inseguras de iniciar manipuladores externos.<\/p>\n

\u00c9 importante destacar que o incidente voltou a chamar a aten\u00e7\u00e3o para os problemas de integra\u00e7\u00e3o de desktop dos mecanismos sandbox no Linux. Apesar da isola\u00e7\u00e3o do Flatpak, erros em componentes de desktop e manipuladores MIME\/URI continuam a ser uma das principais maneiras de contornar as restri\u00e7\u00f5es.<\/p>\n
