A vulnerability was discovered where specific command line arguments are
not properly discarded during Firefox invocation as a shell handler for
URLs. This could be used to retrieve and execute files whose location is
supplied through these command line arguments if Firefox is configured as
the default URI handler for a given URI scheme in third party applications
and these applications insufficiently sanitize URL data. Note: This issue
only affects Windows operating systems. Other operating systems are
unaffected.. This vulnerability affects Thunderbird < 60.6, Firefox ESR <
60.6, and Firefox < 66.
