   An update that solves two vulnerabilities and has one
   errata is now available.

Description:

   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. (bsc#1021669)
   - CVE-2016-1245: Stack overrun in IPv6 RA receive code. (bsc#1005258)

   Bug fixes:

   - Do not enable zebra's TCP interface (port 2600) to use default UNIX
     socket for communication between the daemons. (fate#323170)

   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 (on|off)' 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 (ECMP).
   - 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.
