FreeRADIUS is prone to a heap-corruption vulnerability when handling of tag-field input. An attacker may be able to exploit this issue to deny service to legitimate users of a vulnerable FreeRADIUS server.
This issue was initially reported as a vulnerability in how the software handles 'Tunnel-Password' attribute in Access-Request packets, but the issue turns out to have wider scope, affecting tag-field input in general.
This vulnerability affects FreeRADIUS 0.4.0 through 0.9.2.
UPDATE (September 9, 2009): This issue was fixed in 2003 but reintroduced later. FreeRADIUS 1.1.3 through 1.1.7 are also vulnerable.
