rdesktop vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

An attacker could access your files if rdesktop connected to a malicious
server.

Software Description:
- rdesktop: RDP client for Windows NT/2000 Terminal Server

Details:

It was discovered that rdesktop incorrectly handled specially crafted
paths when using disk redirection. If a user were tricked into connecting
to a malicious server, an attacker could access arbitrary files on the
user's filesystem.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
  rdesktop                        1.6.0-3ubuntu4.1

Ubuntu 10.04 LTS:
  rdesktop                        1.6.0-2ubuntu3.1
