Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Bug Fix Advisory, ELBA-2017-1674-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Oracle Enhanced
RHCK 7 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Improved fix to CVE-2017-1000364 to allow stack expansion close to userspace guard.

Some userspace applications like the Java Virtual Machine are trying to
implement a stack guard area manually by using a fixed mapping which,
together with the original Redhat fix for CVE-2017-1000364, prevents stack
expansion when it shouldn't have.

SUPPORT

Ksplice support is available at ksplice-support_ww at oracle.com.
