N6841A RF Sensor Software
Version 2.4.0
Release Notes
12 May 2022

1. Added a hidden preference to increase the max allowed value that the user can enter for the number of measurements to keep in the database.
To change the value:
  - Open the preference file in a text editor. If the file doesn't exist, create it with notepad.
    Dir  : C:\Program Files (x86)\Keysight\RFSensor\SMT\configuration\.settings\
    File : com.keysight.tentacle.richClient.tdoa.prefs
  - Add this line with the desired value. Example:
    prefs.tdoa.nDbMeasurementsMaxAllowedValue=200000
  - Launch a new instance of the Sensor Management Tool GUI.
2. Vulnerability fixes:
  - directory traversal vulnerability - an attacker can obtain arbitrary operating system files. 
  - deserialization vulnerability - without the need for authentication, an attacker could execute arbitrary code.
3. Bug fixes:
  - IQ streaming fails when the delay length is modified.
  - IQ streaming fails when rapidly changing frequency via salModifyTimeDataFrequency()
  - Multi DDC crash under slow networking conditions
  - Memory leak/crashes in salRequestTimeDataMulti() when IQ cut start fails for whatever reason (usually a timeout)
