INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 14.04 Trusty
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

mounted eCryptfs filesystem.  Please unmount them temporarily whilst
running uptrack-upgrade.

DESCRIPTION

* CVE-2016-1583: Privilege escalation in eCryptfs.

eCryptfs was incorrectly trying to use the mmap() file operation on lower
filesystem that may not support it.  A local, unprivileged user could use
this flaw to cause a denial-of-service through recursive faults or
potentially escalate privileges.
