The Coverity Scan project has discovered a memory leak within the
|
||
|
|
handling of certain malformed Diameter format values inside an EAP-TTLS
|
||
|
|
tunnel.

<impact type="normal">

<p>
|
||
|
|
A remote attacker could send a large amount of specially crafted
|
||
|
|
packets to a FreeRADIUS server using EAP-TTLS authentication and
|
||
|
|
exhaust all memory, possibly resulting in a Denial of Service.

<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.

All FreeRADIUS users should upgrade to the latest version:
