DESCRIPTION:
Some vulnerabilities have been reported in FreeRADIUS, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

The vulnerabilities are caused due to the
"dialup_admin/bin/backup_radacct", "dialup_admin/bin/clean_radacct",
"dialup_admin/bin/monthly_tot_stats", "dialup_admin/bin/tot_stats",
and "dialup_admin/bin/truncate_radacct" scripts handling temporary
files in an insecure manner. These can be exploited via symlink
attacks to e.g. overwrite arbitrary files with escalated privileges.

The vulnerabilities are reported in version 2.0.4. Other versions may
also be affected.
