CVE-2014-0196

Priority
Critical
Description
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through
3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST"
case, which allows local users to cause a denial of service (memory
corruption and system crash) or gain privileges by triggering a race
condition involving read and write operations with long strings.
Ubuntu-Description
A flaw was discovered in the Linux kernel's pseudo tty (pty) device. An
unprivileged user could exploit this flaw to cause a denial of service
(system crash) or potentially gain administrator privileges.
