SUSE Security Update: Security update for quagga ______________________________________________________________________________ Announcement ID: SUSE-SU-2017:2294-1 Rating: important References: #1005258 #1021669 #1034273 Cross-References: CVE-2016-1245 CVE-2017-5495 Affected Products: SUSE Linux Enterprise Software Development Kit 12-SP3 SUSE Linux Enterprise Software Development Kit 12-SP2 SUSE Linux Enterprise Server for Raspberry Pi 12-SP2 SUSE Linux Enterprise Server 12-SP3 SUSE Linux Enterprise Server 12-SP2 ______________________________________________________________________________ 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. Patch Instructions: To install this SUSE Security Update use YaST online_update.
