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 |
|

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" |
68 |
