INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 on
OL6 and OL7 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION

* Deadlock when setting posix access control list of a node in OCFS2 filesystem.

A logic error when setting posix access control list of a new node in
OCFS2 filesystem could lead to a deadlock. A local attacker could use
this flaw to cause a denial-of-service.
