Detailsinfo

A vulnerability has been found in freeRADIUS 1.1.5 (Network Authentication Software) and classified as problematic. Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a memory leak vulnerability. The CWE definition for the vulnerability is CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. As an impact it is known to affect availability. The summary by CVE is:

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.

The bug was discovered 04/10/2007. The weakness was published 04/13/2007 with Coverity (Website). It is possible to read the advisory at vupen.com. This vulnerability is known as CVE-2007-2028 since 04/13/2007. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 67489 (Oracle Linux 3 / 4 / 5 : freeradius (ELSA-2007-0338)), which helps to determine the existence of the flaw in a target environment.
