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.
