Description |
|
|
Se ha descubierto múltiples vulnerabilidades en cfengine 1.6.5 y cfengine 2.1.16, y anteriores. Las vulnerabilidades son descritas a continuación: - CAN-2005-2960: La vulnerabilidad reside en la función "contrib/vicf.in" que crea ficheros temporales de forma insegura en /tmp. Un atacante local podría crear o sobrescribir ficheros arbitrarios, en los que la víctima que ejecuta el script, que probablemente sea root, tenga permiso de escritura, mediante un ataque de enlace simbólico. - CAN-2005-3137: La vulnerabilidad reside en las funciones "contrib/vicf.in" y "/bin/cfmailfilter" que crean ficheros temporales de forma insegura en /tmp. Un atacante local podría crear o sobrescribir ficheros arbitrarios, en los que la víctima que ejecuta el script tenga permiso de escritura, mediante un ataque de enlace simbólico. |
