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

* Race condition when sending IB subnet MAD causes denial-of-service.

When allocating an Infiniband management diagram packet for the
Infiniband subnet manager, the request data might be freed before the
diagram is fully transmitted, resulting in a use-after-free and
denial-of-service.
