Thomas Walpuski discovered a buffer overflow that may be exploitable by
|
||
|
|
sending a specially crafted packet. In order to exploit the vulnerable
|
||
|
|
code, an attacker would need to fake the establishment of an L2TP tunnel.

<impact type="high">
|
||
|
|
<p>
|
||
|
|
A remote attacker may be able to execute arbitrary code with the privileges
|
||
|
|
of the user running l2tpd.
