OpenSSH < 4.5 Multiple Vulnerabilities

The installed version of OpenSSH is prior to 4.5 and is affected by the following vulnerabilities:

• A client-side NULL pointer dereference, caused by a protocol error from a malicious server, which could cause the client to crash. (CVE-2006-4925)
• A privilege separation vulnerability exists, which could allow attackers to bypass authentication. The vulnerability is caused by a design error between privileged processes and their child processes. Note that this particular issue is only exploitable when other vulnerabilities are present. (CVE-2006-5794)
• An attacker that connects to the service before it has finished creating keys could force the keys to be recreated. This could result in a denial of service for any processes that relies on a trust relationship with the server. Note that this particular issue only affects the Apple implementation of OpenSSH on Mac OS X. (CVE-2007-0726)
