Descriptions

An issue was discovered in Icinga 2.x through 2.8.1. The daemon creates an icinga2.pid file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for icinga2.pid modification before a root script executes a "kill `cat /pathname/icinga2.pid`" command, as demonstrated by icinga2.init.d.cmake.

Se ha descubierto un problema en Icinga hasta la versión 2.8.1. El demonio crea un archivo icinga2.pid tras eliminar privilegios a una cuenta no root, lo que podría permitir que usuarios locales terminen procesos arbitrarios aprovechando el acceso a esta cuenta no root para modificar el archivo icinga2.pid antes de que un script root ejecute un comando "kill `cat /pathname/icinga2.pid`". Esto se ha demostrado con etc/init.d/icinga2.init.d.cmake.
