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