Description


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.

Am I vulnerable?

The constraints below list the versions that this vulnerability is patched in, and versions that are unaffected. If a patch is ready but unrealeased, then it is pending.

Or, you can just let us figure it out for you! Appcanary continously monitor your installed packages, and tell you if any of them are vulnerable.
