Depending on the version of LANDesk & service pack-level you use, you can request the latest remote control patch from LD support.
9.5 has been EOL'ed last year.
9.6 and version 2016 are currently active.
If you're on something older than 9.5 support can have a dig in the archives to see if there's a newer remote control related patch.
And yes, there will be newer files - the LDMIRROR.DLL on my 9.6 Core for instance is 220.127.116.11 ... so there's been stuff since the 18.104.22.168 release .
