An update that solves two vulnerabilities and has one security fix can now be installed.

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.
