FreeBSD : traefik -- Unexpected behavior with IPv4-mapped IPv6 addresses (219aaa1e-2aff-11ef-ab37-5404a68ad561)

critical Nessus Plugin ID 200643

Language:

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 219aaa1e-2aff-11ef-ab37-5404a68ad561 advisory.

 The traefik authors report:
 There is a vulnerability in Go managing various Is methods (IsPrivate, IsLoopback, etc) for IPv4-mapped IPv6 addresses.
 They didn't work as expected returning false for addresses which would return true in their traditional IPv4 forms.

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.
