This update provides Quagga 1.1.1, which brings several fixes and enhancements. Security issues fixed: - CVE-2017-5495: Telnet "vty" interface DoS due to unbounded memory allocation. - CVE-2016-1245: Stack overrun in IPv6 RA receive code. Bug fixes: - Do not enable zebra"s TCP interface to use default UNIX socket for communication between the daemons. Between 0.99.22.1 and 1.1.1 the following improvements have been implemented: - Changed the default of "link-detect" state, controlling whether zebra will respond to link-state events and consider an interface to be down when link is down. To retain the current behavior save your config before updating, otherwise remove the "link-detect" flag from your config prior to updating. There is also a new global "default link-detect " flag to configure the global default. - Greatly improved nexthop resolution for recursive routes. - Event driven nexthop resolution for BGP. - Route tags support. - Transport of TE related metrics over OSPF, IS-IS. - IPv6 Multipath for zebra and BGP. - Multicast RIB support has been extended. It still is IPv4 only. - RIP for IPv4 now supports equal-cost multipath . - route-maps have a new action set ipv6 next-hop peer-address. - route-maps have a new action set as-path prepend last-as. - next-hop-self all to override nexthop on iBGP route reflector setups. - New pimd daemon provides IPv4 PIM-SSM multicast routing. - IPv6 address management has been improved regarding tentative addresses. This is visible in that a freshly configured address will not immediately be marked as usable. - Recursive route support has been overhauled. Scripts parsing show ip route output may need adaptation. - A large amount of changes has been merged for ospf6d. Careful evaluation prior to deployment is recommended. - Multiprotocol peerings over IPv6 now try to find a more appropriate IPv4 nexthop by looking at the interface. - Relaxed bestpath criteria for multipath and improved display of multipath routes in show ip bgp. Scripts parsing this output may need to be updated. - Support for iBGP TTL security.
