Debian Security Advisory DSA 158-1                     security@debian.org

Package        : gaim
Vulnerability  : arbitrary program execution
Problem-Type   : remote
Debian-specific: no

The developers of Gaim, an instant messenger client that combines
several different networks, found a vulnerability in the hyperlink
handling code.  The 'Manual' browser command passes an untrusted
string to the shell without escaping or reliable quoting, permitting
an attacker to execute arbitrary commands on the users machine.
Unfortunately, Gaim doesn't display the hyperlink before the user
clicks on it.  Users who use other inbuilt browser commands aren't
vulnerable.

This problem has been fixed in version 0.58-2.2 for the current
stable distribution (woody) and in version 0.59.1-2 for the unstable
distribution (sid).  The old stable distribution (potato) is not
affected since it doesn't ship the Gaim program.

The fixed version of Gaim no longer passes the user's manual browser
command to the shell.  Commands which contain the %s in quotes will
need to be amended, so they don't contain any quotes.  The 'Manual'
browser command can be edited in the 'General' pane of the
'Preferences' dialog, which can be accessed by clicking
 'Options' from
the login window, or 'Tools' and then 'Preferences' from the
 menu bar
in the buddy list window.

We recommend that you upgrade your gaim package immediately.

wget url
	will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
