[slackware-security] dhcp (SSA:2009-195-01)
New dhcp packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, 10.2, 11.0, 12.0, 12.1, 12.2, and -current to fix a security issue with dhclient.
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.
More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0692
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: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0692 (* Security fix *) +--------------------------+
Where to find the new packages: +-----------------------------+
HINT: Getting slow download speeds from ftp.slackware.com? Give slackware.osuosl.org a try. This is another primary FTP site for Slackware that can be considerably faster than downloading directly from ftp.slackware.com.
Thanks to the friendly folks at the OSU Open Source Lab (http://osuosl.org) for donating additional FTP and rsync hosting to the Slackware project! :-)
Also see the "Get Slack" section on http://slackware.com for additional mirror sites near you.
