Amazon Linux 1 Security Advisory: ALAS-2014-339
Advisory Release Date: 2014-05-13 16:40 Pacific
Advisory Updated Date: 2014-09-18 00:34 Pacific
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.
Affected Packages:
kernel
Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
