Synopsis: ELSA-2018-4087 can now be patched using Ksplice
CVEs: CVE-2018-1000199

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2018-4087.


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,
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


* CVE-2018-1000199: Denial-of-service in hardware breakpoints.

Incorrect validation of a ptrace hardware breakpoint could result in
corrupted kernel state.  A local, unprivileged user could use this flaw
to crash the system or potentially, escalate privileges.

Orabug: 27947602
