Technical Description

Multiple vulnerabilities have been identified in FreeRADIUS, which could be exploited by local attackers to bypass security restrictions. These issues are caused by errors in the "backup_radacct", "clean_radacct", "monthly_tot_stats", "tot_stats" and "truncate_radacct" scripts in the "dialup_admin/bin" directory when handling temporary files, which could allow malicious users to conduct symlink attacks and overwrite arbitrary files with the privileges of the user invoking the vulnerable application.
