Riverbed Interceptor 1.1.2 Released

Riverbed Interceptor 9200Riverbed has just announced an important update to its Interceptor software.

One of the nicest features is the added RAID alarm command, as well as a fix for unexpected reboots when fragmented packets are taken in by the Riverbed device.

Based on the latter alone, I’d be updating ASAP.

Oh, and also of note: “20042 Fixed a security problem where an attacker can cause scripts to be inserted into logs and executed when the logs are viewed through the web interface.”
