CVE-2013-0160: Infoleak
First published: Tue Jan 08 2013(Updated: )
A security flaw was found in the way "/dev/ptmx", a character device used to create a pseudo-terminal master (PTM) and slave (PTS) pair, of the Linux kernel, used to transmit data through the PTM when a keystroke was pressed. An unprivileged, local user could use this flaw to determine inter-keystroke timing (measure latency between keystrokes), possibly allowing them to determine effective length of an password being typed in.
