Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201610-03
(Quagga: Arbitrary code execution)

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 :

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.

Workaround :

There is no known workaround at this time.
