Lack of buffer clearing before reuse may result in incorrect system behavior.

Summary

The Honeywell Experion PKS and OneWireless WDM contains Sensitive Information in Resource vulnerability in the component Control Data Access (CDA). An attacker could potentially exploit this vulnerability, leading to a Communication Channel Manipulation, which could result in buffer reuse which may cause incorrect system behavior. Honeywell also recommends updating to the most recent version of Honeywell Experion PKS:520.2 TCU9 HF1 and 530.1 TCU3 HF1 and OneWireless: 322.5 and 331.1.  The affected Experion PKS products are C300, FIM4, FIM8, UOC, CN100, HCA, C300PM, and C200E. The Experion PKS versions affected are 520.1 before 520.2 TCU9 HF1 and 530 before 530 TCU3. The OneWireless WDM affected versions are 322.1 through 322.4 and 330.1 through 330.3.
