RedHat releases patch for the 'ptys' default permissions problem
22 Oct. 1999
Summary
The version of 'screen' that is shipped with Red Hat Linux 6.1 defaults to not using Unix98 ptys. Since 'screen' is not setuid root, this means that it leaves the ptys with insecure permissions. Redhat has issued a fixed version of screen that restores the Unix98 pty support.
