      "value": "A Local Privilege Escalation (LPE) vulnerability has been discovered in pam-config within Linux Pluggable Authentication Modules (PAM). This flaw allows an unprivileged local attacker (for example, a user logged in via SSH) to obtain the elevated privileges normally reserved for a physically present, \"allow_active\" user. The highest risk is that the attacker can then perform all allow_active yes Polkit actions, which are typically restricted to console users, potentially gaining unauthorized control over system configurations, services, or other sensitive operations."

      "value": "Se ha descubierto una vulnerabilidad de Escalada de Privilegios Locales (LPE) en pam-config, dentro de los Módulos de Autenticación Conectables (PAM) de Linux. Esta falla permite a un atacante local sin privilegios (por ejemplo, un usuario conectado por SSH) obtener los privilegios elevados normalmente reservados para un usuario \"allow_active\" físicamente presente. El mayor riesgo es que el atacante pueda entonces realizar todas las acciones \"allow_active yes\" de Polkit, que normalmente están restringidas a los usuarios de consola, lo que podría permitirle obtener control no autorizado sobre las configuraciones del sistema, los servicios u otras operaciones sensibles."
