CentOS Errata and Security Advisory CESA-2015:0087

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.
