However, strings indicates that /usr/bin/ssh is also aware for the useroaming configuration option: > strings /usr/bin/ssh | grep -i useroam useroaming Is it actually known that the ssh version shipped with CentOS 6 is not vulnerable, or is it just assumed based on the version number? The announcement implies that the roaming code itself was added in 5.4, not just that...

...e authentication of the server host key prevents exploitation by a man-in-the-middle, so this information leak is restricted to connections to malicious or compromised servers. MITIGATION: For OpenSSH >= 5.4 the vulnerable code in the client can be completely disabled by adding 'UseRoaming no' to the gobal ssh_config(5) file, or to user configuration in ~/.ssh/config, or by passing -oUseRoaming=no on the command line. PATCH: See below for a patch to disable this feature (Disabling Roaming in the Source Code). This problem was reported by the Qualys Security Advis...
