|
Action
|
|
------
|
|
|
|
xCAT uses OpenSSL for client-server communication but **does not** ship it. Regarding CVE-2016-0800, xCAT also does not use SSLv2 layer but uses the newer TLS transport layer security.
|
|
|
|
It is recommended to keep your OpenSSL levels up-to-date with the indicated versions in the security bulletins to prevent any potential security threats.
