Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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 699ef80f-9e91-11f0-bc5f-8447094a420f advisory.

 The LibreSSL project reports:
 An incorrect length check can result in a 4-byte overwrite and an 8-byte overread.

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.

Solution

Update the affected packages.
