GLSA-200605-15 : Quagga Routing Suite: Multiple vulnerabilities

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200605-15
(Quagga Routing Suite: Multiple vulnerabilities)

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 :

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 :

There is no known workaround at this time.

Solution :

All Quagga users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/quagga-0.98.6-r1'

Risk factor :

Medium / CVSS Base Score : 5.0
