>Description:
An out-of-the-box FreeBSD installation with amd enabled will generate two
system log messages of the form "embedded slash in map name "/etc/amd.map"
-- possible spoof attempt from nn.nn.nn.nn:773".
>How-To-Repeat:
Install FreeBSD 6.x or 7.x. Add the line "amd_enable="YES"" to /etc/rc.conf.
>Fix:
The default flags specify a map of /etc/amd.map for /host and /net. With
no further configuration options, amd will try to interpret /etc/amd.map
as an NIS map name before trying to interpret it as a plain file name. To
fix the problem, patch /usr/src/contrib/amd/amd/mapc.c to move the "file"
map type entry in maptypes before the NIS+ and NIS map type entries:
