After getting reports about a possible vulnerability of Roundcube
which allows an attacker to modify its users preferences in a way that
he/she can then read files from the server, we now published updated
packages as well as patches that fix this security issue.

Please update all your Roundcube installations with the new versions
(0.9-rc2, 0.8.6, 0.7.4) or patch them with the published patches.
Download the latest version from http://roundcube.net/download

Patch for 0.9.x: http://ow.ly/jtQD0
Patch for 0.8.x: http://ow.ly/jtQHM
Patch for 0.7.x: http://ow.ly/jtQK0
Patch for 0.6: http://ow.ly/jtQNd

In order to find out whether one of your users has vulnerable
preferences, you can run the following query on the Roundcube user

SELECT * FROM users WHERE preferences LIKE '%generic_message_footer%'

If this returns any results, you should at least clear the
'preferences' field of that user entry. Or better: entirely block the
user because he or she most likely tried to exploit your system.

And here's some background about the vulnerability:
