<title>Quagga Routing Suite: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|
Quagga's RIP daemon allows the injection of routes and the disclosure of
|
|
routing information. The BGP daemon is vulnerable to a Denial of Service.

The Quagga Routing Suite implements three major routing protocols:
|
|
RIP (v1/v2/v3), OSPF (v2/v3) and BGP4.

Konstantin V. Gavrilenko discovered two flaws in the Routing
|
|
Information Protocol (RIP) daemon that allow the processing of RIP v1
|
|
packets (carrying no authentication) even when the daemon is configured
|
|
to use MD5 authentication or, in another case, even if RIP v1 is
|
|
completely disabled. Additionally, Fredrik Widell reported that the
|
|
Border Gateway Protocol (BGP) daemon contains a flaw that makes it lock
|
|
up and use all available CPU when a specific command is issued from the
|
|
telnet interface.

<impact type="normal">
|
|
<p>
|
|
By sending RIP v1 response packets, an unauthenticated attacker
|
|
can alter the routing table of a router running Quagga's RIP daemon and
|
|
disclose routing information. Additionally, it is possible to lock up
|
|
the BGP daemon from the telnet interface.
|
|

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|

</workaround>

<resolution>
|
|
<p>
|
|
All Quagga users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/quagga-0.98.6-r1"</code>
