Resolution
                            
                            
                                No action is required.
Citrix License Server does not contain the affected modules: mod_macro and does not use HTTP/2 and is therefore not affected. The next version of the Citrix licensing server would have a newer Apache version as well.
Customers may also wish to upgrade to build 45000 which utilizes Apache 2.4.58, but this is not necessary to mitigate the CVE issues as the previous version was not impacted.
