How to fix?

Upgrade fluentd to version 0.12.41 or higher.

Overview

Affected versions of this package are vulnerable to Improper Neutralization via the filter_parser.rb:filter_stream function. Exploiting this vulnerability may allow an attacker to change the terminal UI or execute arbitrary commands on the victim's device via unspecified vectors.

NOTE: A vulnerable system requires all of the following conditions to be existing:

  1. A filter_parser enabled in fluentd.conf

  2. Fluentd is running in non-daemon mode or a bad Syslog server that doesn't sanitize escape sequences (rsyslog does)

  3. A vulnerable terminal that happens to be running fluentd or manipulating the fluentd log file.
