  script_tag(name:"insight", value:"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<pipe>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.");
