Konstantin Gavrilenko discovered several vulnerabilities in quagga, the BGP/OSPF/RIP routing daemon. The Common Vulnerabilities and Exposures project identifies the following problems:
Remote attackers may obtain sensitive information via RIPv1 REQUEST packets even if the quagga has been configured to use MD5 authentication.
Remote attackers could inject arbitrary routes using the RIPv1 RESPONSE packet even if the quagga has been configured to use MD5 authentication.
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.
