Red Hat Security Advisory 2017-2681-01
Posted Sep 13, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-2681-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A stack buffer overflow flaw was found in the way the Bluetooth subsystem of the Linux kernel processed pending L2CAP configuration responses from a client. On systems with the stack protection feature enabled in the kernel, an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to crash the system. Due to the nature of the stack protection feature, code execution cannot be fully ruled out, although we believe it is unlikely. On systems without the stack protection feature, an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to remotely execute arbitrary code on the system with ring 0 privileges.

                   Red Hat Security Advisory

Synopsis:          Important: kernel security update
Advisory ID:       RHSA-2017:2681-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:2681
Issue date:        2017-09-12
CVE Names:         CVE-2017-1000251 
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64

Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

3. Description:

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

Security Fix(es):

* A stack buffer overflow flaw was found in the way the Bluetooth subsystem
of the Linux kernel processed pending L2CAP configuration responses from a
client. On systems with the stack protection feature enabled in the kernel
(CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other
than s390x and ppc64[le]), an unauthenticated attacker able to initiate a
connection to a system via Bluetooth could use this flaw to crash the
system. Due to the nature of the stack protection feature, code execution
cannot be fully ruled out, although we believe it is unlikely. On systems
without the stack protection feature (ppc64[le]; the Bluetooth modules are
not built on s390x), an unauthenticated attacker able to initiate a
connection to a system via Bluetooth could use this flaw to remotely
execute arbitrary code on the system with ring 0 (kernel) privileges.
(CVE-2017-1000251, Important)

Red Hat would like to thank Armis Labs for reporting this issue.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

1489716 - CVE-2017-1000251 kernel: stack buffer overflow in the native Bluetooth stack
