Description

Kostya Kortchinsky discovered a stack-based buffer overflow vulnerability in the VPNv4 NLRI parser in bgpd in quagga, a BGP/OSPF/RIP routing daemon. A remote attacker can exploit this flaw to cause a denial of service (daemon crash), or potentially, execution of arbitrary code, if bgpd is configured with BGP peers enabled for VPNv4.
