Test ID:1.3.6.1.4.1.25623.1.0.871150
Category:Red Hat Local Security Checks
Title:RedHat Update for kernel RHSA-2014:0328-01
Summary:The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

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

* A flaw was found in the way the get_rx_bufs() function in the vhost_net
implementation in the Linux kernel handled error conditions reported by the
vhost_get_vq_desc() function. A privileged guest user could use this flaw
to crash the host. (CVE-2014-0055, Important)

* A flaw was found in the way the Linux kernel processed an authenticated
COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote
attacker could use this flaw to crash the system by initiating a specially
crafted SCTP handshake in order to trigger a NULL pointer dereference on
the system. (CVE-2014-0101, Important)

* A flaw was found in the way the Linux kernel's CIFS implementation
handled uncached write operations with specially crafted iovec structures.
An unprivileged local user with access to a CIFS share could use this flaw
to crash the system, leak kernel memory, or, potentially, escalate their
privileges on the system. Note: the default cache settings for CIFS mounts
on Red Hat Enterprise Linux 6 prohibit a successful exploitation of this
issue. (CVE-2014-0069, Moderate)

* A heap-based buffer overflow flaw was found in the Linux kernel's cdc-wdm
driver, used for USB CDC WCM device management. An attacker with physical
access to a system could use this flaw to cause a denial of service or,
potentially, escalate their privileges. (CVE-2013-1860, Low)

Red Hat would like to thank Nokia Siemens Networks for reporting
CVE-2014-0101, and Al Viro for reporting CVE-2014-0069.

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.

Affected Software/OS:
kernel on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
