At this time I am not seeing a firmware update for the older Drac5, likely due to it being End of Life. Currently I am only seeing the firmware release in the iDrac series. The iDrac 7 and 8 were repaired with fw 126.96.36.199, with the iDrac 6's firmware release coming up shortly. . I will research if any upcoming updates address the issue for the Drac 5 model. If you follow this link though it will show you some resolutions, as well as a hotfix for the CVE-2014-3566 Poodle Vulnerability.
Hope this helps. I will let you know if I discover anything on an update, or its release time.
