Vulnerability CVE-2011-4190

Vulnerability Name:

CVE-2011-4190 (CCN-152219)

Assigned:

2011-10-25

Published:

2012-02-09

Updated:

Summary:

The kdump implementation is missing the host key verification in the kdump and mkdumprd OpenSSH integration of kdump prior to version 2012-01-20. This is similar to CVE-2011-3588, but different in that the kdump implementation is specific to SUSE. A remote malicious kdump server could use this flaw to impersonate the correct kdump server to obtain security sensitive information (kdump core files).
