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.
Solution: Update to version 2.1.3.
Provided and/or discovered by: Reported by Dmitry E. Oboukhov in a Debian bug report.
