quagga: multiple vulnerabilities

Package(s):quagga CVE #(s):CVE-2006-2223 CVE-2006-2224 CVE-2006-2276
Created:May 15, 2006 Updated:July 24, 2006
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)

Corrections, for the record:

I, Paul Jakma, did not notice the RIP problems, it was Konstantin V. Gavrilenko of Arhont. Who then reported them to myself and the other Quagga maintainers. I fixed the issues, with assistance from Konstantin in testing proposed fixes against the issues he had reported.
