In EmberZNet v9.0.2 and earlier, malformed OTA requests can drive the OTA server parser into out-of-bounds reads. A limited amount of data from RAM is read back to the requester. The size and location of this data is limited. These requests must come from a device that has already joined the network. Only devices supporting the OTA Server cluster may be impacted.
