<description>
|
|
<p>A memcpy function in the VPNv4 NLRI parser of bgp_mplsvpn.c does not
|
|
properly check the upper-bound length of received Labeled-VPN SAFI routes
|
|
data, which may allow for arbitrary code execution on the stack.

<impact type="high">
|
|
<p>A remote attacker could send a specially crafted packet, possibly
|
|
resulting in execution of arbitrary code with the privileges of the
|
|
process or a Denial of Service condition.

</impact>
