Fedora 26: 2020-a3c9d6e4c Moderate: Quagga Heap Overflow in bgpd

Quagga is free software that operates TCP/IP-based routing protocols. It takes

a multi-server and multi-threaded approach to resolving the current complexity

of the Internet.

Quagga supports Babel, BGP4, BGP4+, BGP4-, IS-IS (experimental), OSPFv2,

OSPFv3, RIPv1, RIPv2, RIPng, PIM-SSM and NHRP.

Quagga is intended to be used as a Route Server and a Route Reflector. It is

not a toolkit; it provides full routing power under a new architecture.

Quagga by design has a process for each protocol.

Quagga is a fork of GNU Zebra.
