Los desarrolladores de Mozilla han lanzado nuevas versiones de los navegadores web Firefox 74.0.1 y Firefox ESR 68.6.1. Se recomienda a los usuarios actualizar sus navegadores, ya que en las versiones presentadas se han corregido dos vulnerabilidades de d\u00eda cero que son utilizadas por hackers en la pr\u00e1ctica.<\/p>\n

\"Se<\/p>\n

Las vulnerabilidades son CVE-2020-6819 y CVE-2020-6820, relacionadas con la forma en que Firefox gestiona su espacio de memoria. Se trata de las llamadas vulnerabilidades de uso de memoria despu\u00e9s de la liberaci\u00f3n, que permiten a los hackers colocar c\u00f3digo arbitrario en la memoria de Firefox para su posterior ejecuci\u00f3n en el contexto del navegador. Estas vulnerabilidades pueden ser utilizadas para la ejecuci\u00f3n remota de c\u00f3digo en los dispositivos de la v\u00edctima.<\/p>\n

No se revela informaci\u00f3n detallada sobre ataques reales que utilizan las vulnerabilidades mencionadas, lo cual es una pr\u00e1ctica com\u00fan entre los proveedores de software e investigadores en ciberseguridad. Esto se debe a que todos ellos normalmente se enfocan en reparar r\u00e1pidamente los problemas detectados y entregar correcciones a los usuarios, y despu\u00e9s de eso se lleva a cabo una investigaci\u00f3n m\u00e1s detallada de los ataques.<\/p>\n

Seg\u00fan la informaci\u00f3n disponible, la investigaci\u00f3n de ataques que utilizan estas vulnerabilidades ser\u00e1 realizada por Mozilla en colaboraci\u00f3n con la empresa de ciberseguridad JMP Security y el investigador Francisco Alonso, quien fue el primero en descubrir el problema. El investigador sugiere que las vulnerabilidades corregidas en la \u00faltima actualizaci\u00f3n de Firefox podr\u00edan afectar a otros navegadores, aunque no se conocen casos en los que los errores hayan sido explotados por hackers en diferentes navegadores web.<\/p>\n
