Slackware :: Dhclient Does Not Strip Or Escape Shell Meta-characters

Apr 6, 2011

dhclient does not strip or escape shell meta-characters

Summary: dhclient doesn't strip or escape certain shell meta-characters in dhcpd responses, allowing a rogue server or party with with escalated privileges on the server to cause remote code execution on the client.


ISC dhclient did not strip or escape certain shell meta-characters in responses from the dhcp server (like hostname) before passing the responses on to dhclient-script. Depending on the script and OS, this can result in execution of exploit code on the client.

CVSS Score:

For more information on CVSS scores, visit [url]


On SUSE systems, it is possible to disable hostname update by setting DHCLIENT_SET_HOSTNAME="no" in /etc/sysconfig/network/dhcp.

Other systems may add following line to dhclient-script at the beginning of the set_hostname() function:

In environments where filters/acls can be put into place to limit clients to accessing only legitimate dhcp servers, this will protect clients from rogue dhcp servers deliberately trying to exploit this bug.

However, this will not protect from compromised servers.

Active exploits:


Upgrade to 3.1-ESV-R1, 4.1-ESV-R2 or 4.2.1-P1. [url]

No patch is available for 4.0.x as it is EOL. Anyone running 4.1.x should upgrade to 4.1-ESV-R2.

General :: Convert Shell Logs - Incl. Escape Characters - To HTML?

Mar 6, 2010

Is there tool or a regexp that can convert shell escape characters to HTML code?

As an example, here is a logfile from GNU screen:

Which I would like to convert to something like this:

And send as HTML e-mail to an e-mail address, to archive my work.

Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.

Ubuntu :: Switch Desktop Shell From Unity To Gnome-shell?

Apr 14, 2011

Is there any way I can switch my desktop shell from unity to, say, gnome-shell? I can switch using other console shell I like (bash, csh, fish, etc.). Assume that there is a stable alternative desktop shell, I should be able to choose, too.

(For console shell, we goes to /etc/passwd. But for desktop, I can't find the way to config.)

Server :: Which Php Command For Shell Interaction Shall Use?

Dec 26, 2010

As homework for my study I have to do some kind of browser GUI to send commands to mysql command line tool and to show the output in the browser. I already set up sudo to have the right permissions for the www-data user. In the php documentation I found that one of the following four commands are probably for tasks like mine.

shell exec

Can anyone tell me which one is the best for my requirements? The idea is to use php from the browser to connect to mysql like on the command line with: "mysql �user=username �password" And then give back the output of the command line to the browser. If the above is working then the next step would be to put a link in order to execute the command �show database;� again through php by clicking that link. After clicking this link it would give back to the browser what the command line would display.
