1. Summary:

 

Updated kernel packages that fix multiple security issues, address several

hundred bugs, and add numerous enhancements are now available as part of

the ongoing support and maintenance of Red Hat Enterprise Linux version 7.

This is the first regular update.

3. Description:

 

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 XFS file system handled

replacing of remote attributes under certain conditions. A local user with

access to XFS file system mount could potentially use this flaw to escalate

their privileges on the system. (CVE-2015-0274, Important)

 

* It was found that the Linux kernel's KVM implementation did not ensure

that the host CR4 control register value remained unchanged across VM

entries on the same virtual CPU. A local, unprivileged user could use this

flaw to cause denial of service on the system. (CVE-2014-3690, Moderate)

 

* A flaw was found in the way Linux kernel's Transparent Huge Pages (THP)

implementation handled non-huge page migration. A local, unprivileged user

could use this flaw to crash the kernel by migrating transparent hugepages.

(CVE-2014-3940, Moderate)

 

* An out-of-bounds memory access flaw was found in the syscall tracing

functionality of the Linux kernel's perf subsystem. A local, unprivileged

user could use this flaw to crash the system. (CVE-2014-7825, Moderate)

 

* An out-of-bounds memory access flaw was found in the syscall tracing

functionality of the Linux kernel's ftrace subsystem. On a system with

ftrace syscall tracing enabled, a local, unprivileged user could use this

flaw to crash the system, or escalate their privileges. (CVE-2014-7826,

Moderate)

 

* A race condition flaw was found in the Linux kernel's ext4 file system

implementation that allowed a local, unprivileged user to crash the system

by simultaneously writing to a file and toggling the O_DIRECT flag using

fcntl(F_SETFL) on that file. (CVE-2014-8086, Moderate)

 

* A flaw was found in the way the Linux kernel's netfilter subsystem

handled generic protocol tracking. As demonstrated in the Stream Control

Transmission Protocol (SCTP) case, a remote attacker could use this flaw to

bypass intended iptables rule restrictions when the associated connection

tracking module was not loaded on the system. (CVE-2014-8160, Moderate)

 

* It was found that due to excessive files_lock locking, a soft lockup

could be triggered in the Linux kernel when performing asynchronous I/O

operations. A local, unprivileged user could use this flaw to crash the

system. (CVE-2014-8172, Moderate)

 

* A NULL pointer dereference flaw was found in the way the Linux kernel's

madvise MADV_WILLNEED functionality handled page table locking. A local,

unprivileged user could use this flaw to crash the system. (CVE-2014-8173,

Moderate)

 

* An information leak flaw was found in the Linux kernel's IEEE 802.11

wireless networking implementation. When software encryption was used, a

remote attacker could use this flaw to leak up to 8 bytes of plaintext.

(CVE-2014-8709, Low)

 

* A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge

DEC USB device driver. A local user with write access to the corresponding

device could use this flaw to crash the kernel or, potentially, elevate

their privileges on the system. (CVE-2014-8884, Low)

 

Red Hat would like to thank Eric Windisch of the Docker project for

reporting CVE-2015-0274, Andy Lutomirski for reporting CVE-2014-3690, and

Robert Święcki for reporting CVE-2014-7825 and CVE-2014-7826.

 

This update also fixes several hundred bugs and adds numerous enhancements.

Refer to the Red Hat Enterprise Linux 7.1 Release Notes for information on

the most significant of these changes, and the following Knowledgebase

article for further information: https://access.redhat.com/articles/1352803

 

All Red Hat Enterprise Linux 7 users are advised to install these updated

packages, which correct these issues and add these enhancements. The system

must be rebooted for this update to take effect.
