INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR6 5.4.17 on
OL7 and OL8 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 the XFS filesystem when allocating an Allocation Group Free List.

A logic error in the XFS filesystem when allocating AGFLs could lead to a
deadlock.  A local, unprivileged user could use this flaw to cause a
denial-of-service.
