Name of the Vulnerable Software and Affected Versions kdump versions prior to 2012-01-20

Description The issue is related to the missing host key verification in the kdump and mkdumprd OpenSSH integration of kdump. This could allow a remote malicious kdump server to impersonate the correct kdump server, potentially obtaining security-sensitive information, such as kdump core files.
