CVE-2014-0196
Published: 5 May 2014
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.
From the Ubuntu security team
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.
