Synopsis: ELSA-2018-4228 can now be patched using Ksplice
CVEs: CVE-2018-0739

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2018-4228.


We recommend that all users of Ksplice on OL 6 install these updates.

You can install these updates by running:

# ksplice -y user upgrade

32-bit applications should be restarted after upgrading the on-disk
openssl RPMs and statically linked applications using
openssl should be rebuilt to include these fixes.

Ksplice user-space patching requires installation of Ksplice-aware
packages and the system must be rebooted after the first installation of
these packages.  Refer to the installation instructions for the Enhanced
Ksplice Client in the Ksplice User's Guide for more details.  Systems
may be prepared for Ksplice patching by installing the Ksplice aware
packages in advance, prior to installing the enhanced Ksplice client.


* CVE-2018-0739: Denial-of-service in ASN.1 recursive definitions.

Constructed ASN.1 types with a recursive definition could result in a
stack overflow.  A malicious remote user could use this flaw against a
vulnerable application to trigger a crash and denial of service.


Ksplice support is available at ksplice-support_ww at oracle.com.
