- Update to version 1.6.8
* Fix CVE-2019-16159:
BIRD Internet Routing Daemon 1.6.x through 1.6.7 and 2.x through
2.0.5 has a stack-based buffer overflow. The BGP daemon's
support for RFC 8203 administrative shutdown communication
messages included an incorrect logical expression when checking
the validity of an input message. Sending a shutdown
communication with a sufficient message length causes a four-byte
overflow to occur while processing the message, where two of the
overflow bytes are attacker-controlled and two are fixed.
* Several important bugfixes
