5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

The OSI networking kernel (sys/netiso) in NetBSD 1.6.1 and earlier does not use a BSD-required "PKTHDR" mbuf when sending certain error responses to the sender of an OSI packet, which allows remote attackers to cause a denial of service (kernel panic or crash) via certain OSI packets.

Affected configurations

• netbsd netbsd 1.5 • netbsd netbsd 1.5.1 • netbsd netbsd 1.5.2 • netbsd netbsd 1.5.3 • netbsd netbsd 1.6 • netbsd netbsd 1.6.1
