Gravity: 2/4

Consequences: privileged access/rights, denial of service of
service

Provenance: LAN

IMPACTED PRODUCTS

 NetBSD [confidential versions]

DESCRIPTION

PPPoE is the PPP encapsulation protocol for ethernet.

It is possible to forge PPPoE packet with a malicious "Length"
tag. The kernel will not be able to treat the packet and this will
generate a denial of service of the system.

An attacker can therefore send a malicious PPPoE packet to a
victim, in order to generate a denial of service.
