FreeBSD : OpenVPN -- avoid buffer overread parsing routes or endpoints (50a0c266-c3ff-11f0-b513-0da7be77c170)

critical Nessus Plugin ID 275732

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 50a0c266-c3ff-11f0-b513-0da7be77c170 advisory.

 Mikhail Khachaiants reports:
 socket: reject mismatched address family in get_addr_generic.
 Add a family check to prevent copying address data of the wrong type, which could cause buffer over-read when parsing routes or endpoints.

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.
