{"schemaVersion":3,"id":"SUSE-SU-2017:2294-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for quagga\n\nThis update provides Quagga 1.1.1, which brings several fixes and enhancements.\n\nSecurity issues fixed:\n\n- CVE-2017-5495: Telnet 'vty' interface DoS due to unbounded memory allocation. (bsc#1021669)\n- CVE-2016-1245: Stack overrun in IPv6 RA receive code. (bsc#1005258)\n\nBug fixes:\n\n- Do not enable zebra's TCP interface (port 2600) to use default UNIX socket for communication\n  between the daemons. (fate#323170)\n\nBetween 0.99.22.1 and 1.1.1 the following improvements have been implemented:\n\n- Changed the default of 'link-detect' state, controlling whether zebra will respond to\n  link-state events and consider an interface to be down when link is down. To retain the\n  current behavior save your config before updating, otherwise remove the 'link-detect'\n  flag from your config prior to updating. There is also a new global 'default link-detect\n  (on|off)' flag to configure the global default.\n- Greatly improved nexthop resolution for recursive routes.\n- Event driven nexthop resolution for BGP.\n- Route tags support.\n- Transport of TE related metrics over OSPF, IS-IS.\n- IPv6 Multipath for zebra and BGP.\n- Multicast RIB support has been extended. It still is IPv4 only.\n- RIP for IPv4 now supports equal-cost multipath (ECMP).\n- route-maps have a new action 'set ipv6 next-hop peer-address'.\n- route-maps have a new action 'set as-path prepend last-as'.\n- 'next-hop-self all' to override nexthop on iBGP route reflector setups.\n- New pimd daemon provides IPv4 PIM-SSM multicast routing.\n- IPv6 address management has been improved regarding tentative addresses. This is visible in\n  that a freshly configured address will not immediately be marked as usable.\n- Recursive route support has been overhauled. Scripts parsing 'show ip route' output may need\n  adaptation.\n- A large amount of changes has been merged for ospf6d. Careful evaluation prior to deployment\n  is recommended.\n- Multiprotocol peerings over IPv6 now try to find a more appropriate IPv4 nexthop by looking at\n  the interface.\n- Relaxed bestpath criteria for multipath and improved display of multipath routes in 'show ip bgp'.\n  Scripts parsing this output may need to be updated.\n- Support for iBGP TTL security.","dates":{"published":"2017-08-29T14:49:01.000Z","modified":"2025-05-02T04:05:07.459Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"quagga&distro=SUSE
