sol15319: Linux kernel TTY vulnerability CVE-2014-0196

Security Advisory

Original Publication Date: 06/05/2014


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. (CVE-2014-0196)


Local users may be able to cause a denial-of-service (DoS) or gain privileges
by triggering a race condition.
