We have had our engineering teams looking at this since yesterday, and hope to have a statement ready by the end of the week. If you read the original advisory, you know that it's a bit complicated and there are various mitigations that can make this a non-issue in some cases. We're going through to determine whether the problem is exploitable on any of our products.
For AirWave specifically, you can preemptively apply a patch without waiting for our analysis. Login to a root shell and execute "yum update glibc" - you'll get the RedHat updated version that way.
