Desarrolladores del servidor de correo Exim notificaron<\/a><\/noindex> a los usuarios sobre el descubrimiento de una vulnerabilidad cr\u00edtica (CVE-2019-15846<\/a><\/noindex>), que permite a un atacante local o remoto ejecutar su c\u00f3digo en el servidor con privilegios de root. Hasta el momento no se han registrado exploits de acceso p\u00fablico para este problema, pero los investigadores que descubrieron la vulnerabilidad han preparado un prototipo preliminar del exploit.<\/p>\n

Para el 6 de septiembre (13:00 MSK) se program\u00f3 un lanzamiento coordinado de actualizaciones de paquetes con las distribuciones y la publicaci\u00f3n de una versi\u00f3n correctiva Exim 4.92.2<\/a><\/noindex>. Hasta ese momento, la informaci\u00f3n detallada sobre el problema no debe<\/a><\/noindex> divulgarse<\/a><\/noindex>. Todos los usuarios de Exim deben prepararse para la instalaci\u00f3n urgente de una actualizaci\u00f3n fuera de programaci\u00f3n. <\/p>\n

Este a\u00f1o, esta es la tercera son cr\u00edticas<\/a><\/noindex> vulnerabilidad<\/a><\/noindex> en Exim. De acuerdo con la encuesta automatizada de septiembre a m\u00e1s de dos millones de servidores de correo, la cuota de Exim es del 57.13% (el a\u00f1o pasado fue del 56.99%), Postfix se utiliza en el 34.7% (34.11%) de los servidores de correo, Sendmail \u2014 3.94% (4.24%), Microsoft Exchange \u2014 0.53% (0.68%).<\/a><\/noindex> m\u00e1s de dos millones de servidores de correo, la cuota de Exim es del 57.13% (hace un a\u00f1o era del 56.99%), Postfix se utiliza en el 34.7% (34.11%) de los servidores de correo, Sendmail \u2014 3.94% (4.24%), Microsoft Exchange \u2014 0.53% (0.68%). <\/p>\n
