SSL compression issues with Access Gateway


CVE-2012-4929 talks about hijacking SSL sessions due to a flaw with SSL
compression. It is a browser related issue but many back end servers have also
fixed in, including Apache. From, we can see
details on the SSLCompression directive

SSLCompression Directive
Description:    Disallow compression on the SSL level
Syntax:    SSLCompression on|off
Default:    SSLCompression on
Context:    server config, virtual host
Status:    Extension
Module:    mod_ssl
Compatibility:    Available in httpd 2.2.24 and later, if using OpenSSL 0.9.8
or later; virtual host scope available if using OpenSSL 1.0.0 or later

The Apache defect shows that it is available in 2.2.24, but that it was also
ported back to the 2.2.22 build. Does the Access Gateway include this fix?
