Tanium Client 7.4.5.1204

Release Date: April 27, 2021.

Special Notes

  • N/A.

New Features

  • The Tanium Platform components now use the http-parser v2.9.4 library.

Improvements

  • The Tanium Client will now log a clearer message when the Sensor evaluation child process exits normally due to a change in the process' environment and will do so only at LogVerbosityLevel=41 and above. This instead of using the less friendly message: Exiting sensor child process because environment changed.
  • The Tanium Client now implements a number of improvements to the way SQLite databases are accessed, which results in reduced disk I/O activity on the endpoint.
  • The Tanium Client now provides a more robust detection and handling for corrupt SQLite database failures.
  • The Tanium Client now operates its action-manager.db in WAL mode to reduce disk activity on the endpoint.
  • The Tanium Client has changed its behavior to operate its sensors.db in both WAL and NORMAL synchronous mode instead of FULL to reduce endpoint disk activity.
  • The Tanium Client now uses the INSERT OR IGNORE SQL vocable instead of REPLACE for Action Manager database elements, thus reducing observed database activity.
  • The Tanium Client now operates the question-answers.db SQLite database in WAL-mode to reduce disk activity on the endpoint.
  • The Tanium Client now operates the reported-strings.db SQLite database in WAL-mode to reduce disk activity on the endpoint.

Bug Fixes

  • The Tanium Client uninstaller on Windows will now uninstall and clean out the installation directory, or error out if the registry key for the installation path ( Path ) is not set. Additionally, they will refuse to uninstall if the uninstaller has a different version than the actual software installed.
  • Fixed a typo in the Tanium Client's install.log with a message that read " tanium-init.datt " instead of the correct tanium-init.dat.
  • Fixed a bug in the v7.4 versions of the Tanium Client which would produce the error No such file or directory: "/logs" for the Download Statuses reserved Sensor.
  • Fixed a bug in the Tanium Client which would cause Actions with a large distribute over time (DoT) to be executed right after the client reset cycle, resulting in an effective DoT which could not be longer than 4 hours.
  • Fixed a problem with the Tanium Client that would leave files behind in the TC/Downloads/logs directory, causing increased I/O activity.
