Description:
Primoz Bratanic has reported some vulnerabilities in FreeRADIUS, which potentially can be exploited by malicious users to conduct SQL injection attacks or to cause a DoS (Denial of Service).

1) A boundary error in the "sql_escape_func()" function in rlm_sql.c can potentially be exploited to cause a buffer overflow via specially crafted input that needs escaping.

Successful exploitation crashes the application.

2) Missing sanitation when calling the "radius_xlat()" function in rlm_sql.c can potentially be exploited by authenticated users to manipulate SQL queries by injecting arbitrary SQL code.
