statement Not vulnerable. This issue did not affect the versions of OpenSSH as shipped with Red Hat Enterprise Linux 3 or later. This issue did not affect the OpenSSL packages as shipped with Red Hat Enterprise Linux 2.1 as they were not compiled with S/Key or BSD_AUTH support. The upstream patch for this issue and CVE-2002-0640 was included in an errata so that users recompiling OpenSSL with support for those authentication methods would also be protected: https://rhn.redhat.com/errata/RHSA-2002-131.html
