Note that dhclient is not the default DHCP client in Slackware's networking
scripts, dhcpcd is. However, if you use dhclient on a network where someone
could deploy a hostile DHCP server, you should upgrade to the new package.

Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 12.2 ChangeLog:
+--------------------------+
patches/packages/dhcp-3.1.2p1-i486-1_slack12.2.tgz: Upgraded.
 A stack overflow vulnerability was fixed in dhclient that could allow
 remote attackers to execute arbitrary commands as root on the system,
 or simply terminate the client, by providing an over-long subnet-mask
 option.
 For more information, see:
