Descriptions
The _expand_arg function in the pam_env module (modules/pam_env/pam_env.c) in Linux-PAM (aka pam) before 1.1.5 does not properly handle when environment variable expansion can overflow, which allows local users to cause a denial of service (CPU consumption).
La función _expand_arg en el módulo pam_env (modules / pam_env / pam_env.c) en Linux-PAM (también conocido como pam) antes de v1.1.5 no controla correctamente cuando la expansión de la variable de entorno puede desbordarse, lo que permite a usuarios locales provocar una denegación de servicio (el consumo de CPU).
