<background>
<p>Quagga is a free routing daemon replacing Zebra supporting RIP, OSPF and
BGP.
</p>
</background>
<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.
</p>
</description>
<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.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Quagga users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/quagga-1.0.20160315"
</code>
