[slackware-security]  dhcp (SSA:2011-097-01)

New dhcp packages are available for Slackware 9.0, 9.1, 10.0, 10.1, 10.2, 11.0,
12.0, 12.1, 12.2, 13.0, 13.1, and -current to fix a security issue.

Here are the details from the Slackware 13.1 ChangeLog:
patches/packages/dhcp-4.1_ESV_R2-i486-1_slack13.1.txz:  Upgraded.
  In dhclient, check the data for some string options for reasonableness
  before passing it along to the script that interfaces with the OS.
  This prevents some possible attacks by a hostile DHCP server.
  For more information, see:
  (* Security fix *)

Where to find the new packages:

HINT:  Getting slow download speeds from
Give a try.  This is another primary FTP site
for Slackware that can be considerably faster than downloading
directly from

Thanks to the friendly folks at the OSU Open Source Lab
( for donating additional FTP and rsync hosting
to the Slackware project!  :-)
