Ubuntu 5.04 / 5.10 : quagga vulnerabilities (USN-284-1)

medium Nessus Plugin ID 21569

Synopsis

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

Description

Paul Jakma discovered that Quagga's ripd daemon did not properly handle authentication of RIPv1 requests. If the RIPv1 protocol had been disabled, or authentication for RIPv2 had been enabled, ripd still replied to RIPv1 requests, which could lead to information disclosure. (CVE-2006-2223)

Paul Jakma also noticed that ripd accepted unauthenticated RIPv1 response packets if RIPv2 was configured to require authentication and both protocols were allowed. A remote attacker could exploit this to inject arbitrary routes. (CVE-2006-2224)

Fredrik Widell discovered that Quagga did not properly handle certain invalid 'sh ip bgp' commands. By sending special commands to Quagga, a remote attacker with telnet access to the Quagga server could exploit this to trigger an endless loop in the daemon (Denial of Service).
(CVE-2006-2276).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected quagga and / or quagga-doc packages.
