Detail

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

- Ubuntu 11.10

Summary:

Light Display Manager would allow unintended access to file descriptors.

Software Description: - lightdm: Display Manager

Details:

Austin Clements discovered that Light Display Manager incorrectly leaked file descriptors to child processes. A local attacker can use this to bypass intended permissions and write to the log file, cause a denial of service, or possibly have another unknown impact.

Update instructions:

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

Ubuntu 11.10:
liblightdm-gobject-1-0 1.0.6-0ubuntu1.4
liblightdm-qt-1-0 1.0.6-0ubuntu1.4
lightdm 1.0.6-0ubuntu1.4
lightdm-gtk-greeter 1.0.6-0ubuntu1.4
lightdm-qt-greeter 1.0.6-0ubuntu1.4

After a standard system update you need to reboot your computer to make all the necessary changes.
