INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR5 4.14.35
on OL7 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

* Deadlock in Reliable Datagram socket connection.

Incorrect locking when establinging a Reliable Datagram Socket
connection could result in a task hang under specific conditions leading
to an I/O stall.

Orabug: 30903659


* Denial-of-service in Reliable Datagram Socket send cancellation.

A number of logic bugs when cancelling an RDS send operation could
result in out-of-bounds accesses and a kernel crash.  A local user could
use this flaw to crash the system, or potentially, escalate privileges.

Orabug: 30903810
