Est\u00e1 disponible una actualizaci\u00f3n de seguridad para Firefox 97.0.2 y 91.6.1 que soluciona dos vulnerabilidades clasificadas como cr\u00edticas. Estas vulnerabilidades permiten eludir la aislaci\u00f3n del sandbox y ejecutar c\u00f3digo con privilegios del navegador al procesar contenido espec\u00edficamente dise\u00f1ado. Se afirma que hay exploits funcionales para ambos problemas que ya est\u00e1n siendo utilizados en ataques. <\/p>\n

No se han revelado detalles espec\u00edficos, pero se sabe que la primera vulnerabilidad (CVE-2022-26485) est\u00e1 relacionada con el acceso a \u00e1reas de memoria ya liberadas (Use-after-free) en el c\u00f3digo que maneja el par\u00e1metro XSLT, mientras que la segunda (CVE-2022-26486) implica el acceso a memoria ya liberada en el marco IPC de WebGPU. <\/p>\n

Se recomienda a todos los usuarios de navegadores basados en Firefox que actualicen de inmediato. Los usuarios de Tor Browser, que se basa en la rama ESR de Firefox 91, deben ser especialmente cuidadosos al instalar las actualizaciones, ya que las vulnerabilidades pueden llevar no solo a la compromisi\u00f3n del sistema, sino tambi\u00e9n a la desanonimizaci\u00f3n del usuario. La actualizaci\u00f3n que soluciona las vulnerabilidades discutidas a\u00fan no est\u00e1 disponible para Tor Browser.
