Amazon Linux 1 Security Advisory: ALAS-2014-363
Advisory Release Date: 2014-06-15 16:30 Pacific
Advisory Updated Date: 2014-09-19 10:25 Pacific
The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification.
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.
