quagga - several

Konstantin Gavrilenko discovered several vulnerabilities in quagga,
the BGP/OSPF/RIP routing daemon. The Common Vulnerabilities and
Exposures project identifies the following problems:

• CVE-2006-2223
  Remote attackers may obtain sensitive information via RIPv1
  REQUEST packets even if the quagga has been configured to use MD5
  authentication.
• CVE-2006-2224
  Remote attackers could inject arbitrary routes using the RIPv1
  RESPONSE packet even if the quagga has been configured to use MD5
  authentication.
• CVE-2006-2276
  Fredrik Widell discovered that local users can cause a denial
  of service in a certain sh ip bgp command entered in the telnet
  interface.

The old stable distribution (woody) does not contain quagga packages.

For the stable distribution (sarge) these problems have been fixed in
version 0.98.3-7.2.

For the unstable distribution (sid) these problems have been fixed in
version 0.99.4-1.

We recommend that you upgrade your quagga package.
