Descriptions

The check_acl function in pam_xauth.c in the pam_xauth module in Linux-PAM (aka pam) 1.1.2 and earlier does not verify that a certain ACL file is a regular file, which might allow local users to cause a denial of service (resource consumption) via a special file.

La función check_acl en pam_xauth.c en el módulo pam_xauth en Linux-PAM (también conocido como pam) v1.1.2 y anteriores no verifica adecuadamente que un cierto archivo ACL es un archivo regular, lo que permite que usuarios locales provoquen una denegación de servicio (consumo de todos los recursos) a través de un archivo especial.
