Package : libndp
Type    : man-in-the-middle
Remote  : Yes
Link    : https://wiki.archlinux.org/title/CVE

Summary

The package libndp before version 1.6-1 is vulnerable to
man-in-the-middle attacks.

Resolution

Upgrade to 1.6-1.

# pacman -Syu "libndp>=1.6-1"

The problem has been fixed upstream in version 1.6

Workaround

None.

Description
==========
Libndp before version 1.6 does properly validate and check the origin of
Neighbor Discovery Protocol (NDP) messages. An attacker on a non-local
network can exploit this flaw to advertise a node as a router, which
allows them to re-route the traffic through an attacker-controlled node.

Impact
=====
A remote unauthenticated attacker is able to send specially crafted
messages to a client and act as a man-in-the-middle between the client
and a server or disrupt client traffic.
