CVE-2007-2028: Freeradius

Medium severity, CVSS 5.0. EPSS: 2.5% chance of exploitation in the next 30 days.

Memory leak in freeRADIUS 1.1.5 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of EAP-TTLS tunnel connections using malformed Diameter format attributes, which causes the authentication request to be rejected but does not reclaim VALUE_PAIR data structures.
