tag_insight = "New dhcpcd packages are available for Slackware 8.1, 9.0, 9.1, 10.0,
10.1, and -current to fix a minor security issue.  The dhcpcd daemon
can be tricked into reading past the end of the DHCP buffer by a
malicious DHCP server, which causes the dhcpcd daemon to crash and
results in a denial of service.  Of course, a malicious DHCP server
could simply give you an IP address that wouldn't work, too, such as
127.0.0.1, but since people have been asking about this issue, here's
a fix, and that's the extent of the impact.  In other words, very
little real impact.";
