Subject: [USN-610-1] LTSP vulnerability
===========================================================
Ubuntu Security Notice USN-610-1 May 06, 2008
ltsp vulnerability
CVE-2008-1293
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 7.04
Ubuntu 7.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
ldm 0.87.1
Ubuntu 7.04:
ldm 5.0.7.1
Ubuntu 7.10:
ldm 5.0.39.1
After a standard system upgrade you need to update your LTSP client chroots
to effect the necessary changes. For more details, please see:
http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/ltsp-updates.html#id531224
Details follow:
Christian Herzog discovered that it was possible to connect to any
LTSP client's X session over the network. A remote attacker could
eavesdrop on X events, read window contents, and record keystrokes,
possibly gaining access to private information.
