Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2015:0087 :

Updated kernel packages that fix two security issues and several bugs
are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

* A flaw was found in the way the Linux kernel's SCTP implementation
validated INIT chunks when performing Address Configuration Change
(ASCONF). A remote attacker could use this flaw to crash the system by
sending a specially crafted SCTP packet to trigger a NULL pointer
dereference on the system. (CVE-2014-7841, Important)

* An integer overflow flaw was found in the way the Linux kernel's
Advanced Linux Sound Architecture (ALSA) implementation handled user
controls. A local, privileged user could use this flaw to crash the
system. (CVE-2014-4656, Moderate)

The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat.

This update also fixes several bugs. Documentation for these changes
will be available shortly from the Technical Notes document linked to
in the References section.

All kernel users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The system
must be rebooted for this update to take effect.
