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

Description

The ip6_savecontrol function in NetBSD 2.0 through 3.0, under certain configurations, does not check to see if IPv4-mapped sockets are being used before processing IPv6 socket options, which allows local users to cause a denial of service (crash) by creating an IPv4-mapped IPv6 socket with the SO_TIMESTAMP socket option set, then sending an IPv4 packet through the socket.

Affected configurations

• netbsd netbsd 2.0 • netbsd netbsd 2.0.2 • netbsd netbsd 2.0.3 • netbsd netbsd 2.1 • netbsd netbsd 3.0
