Descriptions

A privilege escalation vulnerability was found in nagios 4.2.x that occurs in daemon-init.in when creating necessary files and insecurely changing the ownership afterwards. It's possible for the local attacker to create symbolic links before the files are to be created and possibly escalating the privileges with the ownership change.

Es posible que el atacante local cree vínculos simbólicos antes de que se creen los archivos y escale privilegios con el cambio de propiedad.
