Red Hat 6.0: Important dev rxvt screen security patch RHSA-1999:014-01
New dev, rxvt, and screen packages are available that fix a security issue with the packages that originally shipped with Red Hat Linux 6.0
Summary
Summary
Additionally, once this was corrected, screen and rxvt would still chmod the tty devices to potentially insecure modes.
Solution
umount /dev/pts mount /dev/pts
If you get the error message "umount: /dev/pts: device is busy" when trying to unmount the filesystem, you will have to close all connections using the filesystem, such as screen, xterm (and other such X terminal programs), and some remote connections.
