15 Synopsis
16 ========
17
18 Quagga's RIP daemon allows the injection of routes and the disclosure
19 of routing information. The BGP daemon is vulnerable to a Denial of
20 Service.
21
22 Background
23 ==========
24
25 The Quagga Routing Suite implements three major routing protocols: RIP
26 (v1/v2/v3), OSPF (v2/v3) and BGP4.
27
28 Affected packages
29 =================
30
31 -------------------------------------------------------------------
32 Package / Vulnerable / Unaffected
33 -------------------------------------------------------------------
34 1 net-misc/quagga < 0.98.6-r1 >= 0.98.6-r1
35
36 Description
37 ===========
38
39 Konstantin V. Gavrilenko discovered two flaws in the Routing
40 Information Protocol (RIP) daemon that allow the processing of RIP v1
41 packets (carrying no authentication) even when the daemon is configured
42 to use MD5 authentication or, in another case, even if RIP v1 is
43 completely disabled. Additionally, Fredrik Widell reported that the
44 Border Gateway Protocol (BGP) daemon contains a flaw that makes it lock
45 up and use all available CPU when a specific command is issued from the
46 telnet interface.
47
48 Impact
49 ======
50
51 By sending RIP v1 response packets, an unauthenticated attacker can
52 alter the routing table of a router running Quagga's RIP daemon and
53 disclose routing information. Additionally, it is possible to lock up
54 the BGP daemon from the telnet interface.
55
56 Workaround
57 ==========
58
59 There is no known workaround at this time.
60
61 Resolution
62 ==========
63
64 All Quagga users should upgrade to the latest version:
65
66 # emerge --sync
67 # emerge --ask --oneshot --verbose ">=net-misc/quagga-0.98.6-r1"
