Debian DSA-1561-1 : ldm - programming error

medium Nessus Plugin ID 32085

Synopsis

The remote Debian host is missing a security-related update.

Description

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

Solution

Upgrade the ldm package.

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