Description

Multics CTSS on IBM 7094 contains a flaw that may disclose the contents of the password file. The issue occured when multiple instances of the system text editor were invoked, causing the editor to create temporary files with a constant name. This would unexplicably cause the contents of the system CTSS password file to display to any user logging into the system.
