The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the bff06006-c0b7-11f0-ab42-b42e991fc52e advisory.

    https://bugzilla.mozilla.org/buglist.cgi?bug_id=1987237%2C1990079%2C1991715%2C1994994 reports:
    Memory safety bugs. Some of these bugs showed evidence of               memory corruption and we presume that with enough effort               some of these could have been exploited to run arbitrary               code.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
