these updates.

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

take any action.

Alternatively, you can install these updates by running:

DESCRIPTION

* CVE-2016-5195: Privilege escalation when handling private mapping copy-on-write.

A race condition in the memory subsystem could allow write access to
otherwise read-only memory mappings.  A local, unprivileged user could use
this flaw to escalate their privileges.


* Buffer overrun in xfs when listing extended attributes.

Incorrect logic when listing extended attributes on xfs could allow
attribute names to overwrite attribute data. A local user could use this
flaw to corrupt kernel memory and gain elevated privileges.
