Descriptions

Sudo 1.7.0 through 1.7.4p3, when a Runas group is configured, does not properly handle use of the -u option in conjunction with the -g option, which allows local users to gain privileges via a command line containing a "-u root" sequence.

Sudo v1.7.0 hasta v1.7.4p3, cuando el grupo Runas está configurado, no gestiona de forma adecuada el uso de la opción -u junto a la opción -g, lo que permite a usuarios locales obtener privilegios a través de una línea de comandos que contenga una secuencia "-u root".
