The remote Fedora host is missing a security update.
This update fixes moderate vulnerabilities in pam_env, pam_namespace, pam_mail, and pam_xauth modules. Default configurations (or configurations generated by authconfig) are not affected by the pam_mail and pam_namespace vulnerabilities. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
