Summary

The futex_wait function in kernel/futex.c in the Linux kernel before 2.6.37 does not properly maintain a certain reference count during requeue operations, which allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that triggers a zero count.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

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 rhev-hypervisor6 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: a subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
extensions.

A NULL pointer dereference flaw was found in the way the Linux
kernel's networking implementation handled logging while processing
certain invalid packets coming in via a VxLAN interface. A remote
attacker could use this flaw to crash the system by sending a
specially crafted packet to such an interface. (CVE-2014-3535)

Two integer overflow flaws were found in the QEMU block driver for
QCOW version 1 disk images. A user able to alter the QEMU disk image
files loaded by a guest could use either of these flaws to corrupt
QEMU process memory on the host, which could potentially result in
arbitrary code execution on the host with the privileges of the QEMU
process. (CVE-2014-0222, CVE-2014-0223)

Red Hat would like to thank NSA for reporting CVE-2014-0222 and
CVE-2014-0223.

This update also fixes the following bug :

* Previously, an updated version of Qlogic firmware was not supported
in the Red Hat Enterprise Virtualization Hypervisor 6.5 image and an
error message returned when users were using a newer version of Qlogic
firmware. This update includes the latest Qlogic firmware package in
the Red Hat Enterprise Virtualization Hypervisor 6.5 image so no
firmware errors are returned. (BZ#1135780)

This updated package also provides updated components that include
fixes for various security issues. These issues have no security
impact on Red Hat Enterprise Virtualization Hypervisor itself,
however. The security fixes included in this update address the
following CVE numbers :

CVE-2012-6647, CVE-2013-7339, CVE-2014-2672, CVE-2014-2678,
CVE-2014-2706, CVE-2014-2851, CVE-2014-3144, CVE-2014-3145,
CVE-2014-0205, CVE-2014-3917, and CVE-2014-4667 (kernel issues)

Users of the Red Hat Enterprise Virtualization Hypervisor are advised
to upgrade to this updated package."

"Updated kernel packages that fix multiple 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 futex subsystem
handled reference counting when requeuing futexes during futex_wait().
A local, unprivileged user could use this flaw to zero out the
reference counter of an inode or an mm struct that backs up the memory
area of the futex, which could lead to a use-after-free flaw,
resulting in a system crash or, potentially, privilege escalation.
(CVE-2014-0205, Important)

* A NULL pointer dereference flaw was found in the way the Linux
kernel's networking implementation handled logging while processing
certain invalid packets coming in via a VxLAN interface. A remote
attacker could use this flaw to crash the system by sending a
specially crafted packet to such an interface. (CVE-2014-3535,
Important)

* An out-of-bounds memory access flaw was found in the Linux kernel's
system call auditing implementation. On a system with existing audit
rules defined, a local, unprivileged user could use this flaw to leak
kernel memory to user space or, potentially, crash the system.
(CVE-2014-3917, Moderate)

* An integer underflow flaw was found in the way the Linux kernel's
Stream Control Transmission Protocol (SCTP) implementation processed
certain COOKIE_ECHO packets. By sending a specially crafted SCTP
packet, a remote attacker could use this flaw to prevent legitimate
connections to a particular SCTP server socket to be made.
(CVE-2014-4667, Moderate)

Red Hat would like to thank Gopal Reddy Kodudula of Nokia Siemens
Networks for reporting CVE-2014-4667. The security impact of the
CVE-2014-0205 issue was discovered by Mateusz Guzik 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."
