A security issue has been reported in FreeRADIUS, which can be exploited by malicious people to cause a DoS (Denial of Service).
The security issue is caused due to a memory leak (ca. 300bytes) within the handling of certain malformed diameter format values inside an EAP-TTLS tunnel. This can be exploited to exhaust all available memory by sending a large number of malformed authentication requests to a vulnerable server.
The security issue is reported in versions prior to 1.1.6.
Solution: Update to version 1.1.6.
Provided and/or discovered by: The vendor credits the Coverity Project.
