IHS and OpenSSL
How is IBM® HTTP Server (IHS) related to Open SSL?
On Apache HTTP Server, the SSL functionality is achieved using the module "mod_ssl" which is part of Open SSL. Even though the IBM HTTP Server is based on Apache, it does not use "mod_ssl" for SSL, but rather ships it's own Gskit implementation which interfaces with a module named "mod_ibm_ssl".
Furthermore, OpenSSL (mod_ssl) is not supported as a module within the IBM HTTP Server.
Vulnerabilities which are reported against OpenSSL do not apply to the IBM HTTP Server.
For any relevant security issues with IHS, users are encouraged to apply the latest IBM HTTP Server fix pack levels to ensure the web server is patched with latest security fixes.
