Description

The bgp_nlri_parse_vpnv4 function in bgp_mplsvpn.c in the VPNv4 NLRI parser in bgpd in Quagga before 1.0.20160309, when a certain VPNv4 configuration is used, relies on a Labeled-VPN SAFI routes-data length field during a data copy, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted packet. A stack-based buffer overflow flaw was found in the way the Quagga BGP routing daemon (bgpd) handled Labeled-VPN SAFI routes data. A remote attacker could use this flaw to crash the bgpd daemon resulting in denial of service.
