  script_tag(name:"insight", value:"Christian Herzog discovered that within the Linux Terminal Server Project, it was possible to connect to X on any LTSP client from any host on the network, making client windows and keystrokes visible to that host.

NOTE: most ldm installs are likely to be in a chroot environment exported over NFS, and will not be upgraded merely by upgrading the server itself. For example, on the i386 architecture, to upgrade ldm will likely require:

chroot /opt/ltsp/i386 apt-get update chroot /opt/ltsp/i386 apt-get dist-upgrade

For the stable distribution (etch), this problem has been fixed in version 0.99debian11+etch1.

For the unstable distribution (sid), this problem has been fixed in version 2:0.1~bzr20080308-1.

We recommend that you upgrade your ldm package.");
