    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.
