      "value": "The id utility in uutils coreutils exhibits incorrect behavior in its \"pretty print\" output when the real UID and effective UID differ. The implementation incorrectly uses the effective GID instead of the effective UID when performing a name lookup for the effective user. This results in misleading diagnostic output that can cause automated scripts or system administrators to make incorrect decisions regarding file permissions or access control."

La implementación utiliza incorrectamente el GID efectivo en lugar del UID efectivo al realizar una búsqueda de nombre para el usuario efectivo. Esto resulta en una salida de diagnóstico engañosa que puede hacer que scripts automatizados o administradores de sistemas tomen decisiones incorrectas con respecto a los permisos de archivo o el control de acceso."
