"Updated kernel packages that fix two security issues and two bugs are
now available for Red Hat Enterprise Linux 5.

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.

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* It was found that the Xen hypervisor x86 CPU emulator implementation
did not correctly handle certain instructions with segment overrides,
potentially resulting in a memory corruption. A malicious guest user
could use this flaw to read arbitrary data relating to other guests,
cause a denial of service on the host, or potentially escalate their
privileges on the host. (CVE-2015-2151, Important)

This update also fixes the following bugs :

* Previously, the CPU power of a CPU group could be zero. As a
consequence, a kernel panic occurred at 'find_busiest_group+570' with
do_divide_error. The provided patch ensures that the division is only
performed if the CPU power is not zero, and the aforementioned panic
no longer occurs. (BZ#1209728)

* Prior to this update, a bug occurred when performing an online
resize of an ext4 file system which had been previously converted from
ext3. As a consequence, the kernel crashed. The provided patch fixes
online resizing for such file systems by limiting the blockgroup
search loop for non-extent files, and the mentioned kernel crash no
longer occurs. (BZ#1301100)

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."

"Updated kernel packages that fix multiple security issues and two bugs
are now available for Red Hat Enterprise Linux 6.2 Advanced Update
Support.

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 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)

* It was found that the Linux kernel's Infiniband subsystem did not
properly sanitize input parameters while registering memory regions
from user space via the (u)verbs API. A local user with access to a
/dev/infiniband/uverbsX device could use this flaw to crash the system
or, potentially, escalate their privileges on the system.
(CVE-2014-8159, Important)

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* It was found that the parse_rock_ridge_inode_internal() function of
the Linux kernel's ISOFS implementation did not correctly check
relocated directories when processing Rock Ridge child link (CL) tags.
An attacker with physical access to the system could use a specially
crafted ISO image to crash the system or, potentially, escalate their
privileges on the system. (CVE-2014-5471, CVE-2014-5472, Low)

Red Hat would like to thank Mellanox for reporting the CVE-2014-8159
issue. The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat.

This update also fixes the following bugs :

* Previously, certain network device drivers did not accept ethtool
commands right after they were loaded. As a consequence, the current
setting of the specified device driver was not applied and an error
message was returned. The ETHTOOL_DELAY variable has been added, which
makes sure the ethtool utility waits for some time before it tries to
apply the options settings, thus fixing the bug. (BZ#1138299)

* During the memory allocation for a new socket to communicate to the
server, the rpciod daemon released a clean page which needed to be
committed. However, the commit was queueing indefinitely as the commit
could only be provided with a socket connection. As a consequence, a
deadlock occurred in rpciod. This update sets the PF_FSTRANS flag on
the work queue task prior to the socket allocation, and adds the
nfs_release_page check for the flag when deciding whether to make a
commit call, thus fixing this bug. (BZ#1192326)

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."

device file (/dev/fb*) could possibly use this flaw to escalate their

* 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 a denial of service on the system.
(CVE-2014-3690, Moderate)

* It was found that the parse_rock_ridge_inode_internal() function of
the Linux kernel's ISOFS implementation did not correctly check
relocated directories when processing Rock Ridge child link (CL) tags.
An attacker with physical access to the system could use a specially
crafted ISO image to crash the system or, potentially, escalate their
privileges on the system. (CVE-2014-5471, CVE-2014-5472, 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 Mellanox for reporting CVE-2014-8159, and
Andy Lutomirski for reporting CVE-2014-3690. The CVE-2015-1421 issue
was discovered by Sun Baoliang of Red Hat.

This update also fixes the following bugs :

* Previously, a NULL pointer check that is needed to prevent an oops
in the nfs_async_inode_return_delegation() function was removed. As a
consequence, a NFS4 client could terminate unexpectedly. The missing
NULL pointer check has been added back, and NFS4 client no longer
crashes in this situation. (BZ#1187638)

* Due to unbalanced multicast join and leave processing, the attempt
to leave a multicast group that had not previously completed a join
became unresponsive. This update resolves multiple locking issues in
the IPoIB multicast code that allowed multicast groups to be left
before the joining was entirely completed. Now, multicast join and
leave failures or lockups no longer occur in the described situation.
(BZ#1187663)

* A failure to leave a multicast group which had previously been
joined prevented the attempt to unregister from the 'sa' service.
Multiple locking issues in the IPoIB multicast join and leave
processing have been fixed so that leaving a group that has completed
its join process is successful. As a result, attempts to unregister
from the 'sa' service no longer lock up due to leaked resources.
(BZ#1187665)

* Due to a regression, when large reads which partially extended
beyond the end of the underlying device were done, the raw driver
returned the EIO error code instead of returning a short read covering
the valid part of the device. The underlying source code has been
patched, and the raw driver now returns a short read for the remainder
of the device. (BZ#1195746)

which contain backported patches to correct these issues. The system

"Updated kernel packages that fix two security issues and two bugs are
now available for Red Hat Enterprise Linux 5.

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.

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* It was found that the Xen hypervisor x86 CPU emulator implementation
did not correctly handle certain instructions with segment overrides,
potentially resulting in a memory corruption. A malicious guest user
could use this flaw to read arbitrary data relating to other guests,
cause a denial of service on the host, or potentially escalate their
privileges on the host. (CVE-2015-2151, Important)

This update also fixes the following bugs :

* Previously, the CPU power of a CPU group could be zero. As a
consequence, a kernel panic occurred at 'find_busiest_group+570' with
do_divide_error. The provided patch ensures that the division is only
performed if the CPU power is not zero, and the aforementioned panic
no longer occurs. (BZ#1209728)

* Prior to this update, a bug occurred when performing an online
resize of an ext4 file system which had been previously converted from
ext3. As a consequence, the kernel crashed. The provided patch fixes
online resizing for such file systems by limiting the blockgroup
search loop for non-extent files, and the mentioned kernel crash no
longer occurs. (BZ#1301100)

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."

now available for Red Hat Enterprise Linux 5.

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.

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* It was found that the Xen hypervisor x86 CPU emulator implementation
did not correctly handle certain instructions with segment overrides,
potentially resulting in a memory corruption. A malicious guest user
could use this flaw to read arbitrary data relating to other guests,
cause a denial of service on the host, or potentially escalate their
privileges on the host. (CVE-2015-2151, Important)

This update also fixes the following bugs :

* Previously, the CPU power of a CPU group could be zero. As a
consequence, a kernel panic occurred at 'find_busiest_group+570' with
do_divide_error. The provided patch ensures that the division is only
performed if the CPU power is not zero, and the aforementioned panic
no longer occurs. (BZ#1209728)

* Prior to this update, a bug occurred when performing an online
resize of an ext4 file system which had been previously converted from
ext3. As a consequence, the kernel crashed. The provided patch fixes
online resizing for such file systems by limiting the blockgroup
search loop for non-extent files, and the mentioned kernel crash no
longer occurs. (BZ#1301100)

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."

"Updated kernel packages that fix multiple security issues and two bugs
are now available for Red Hat Enterprise Linux 6.4 Advanced Update
Support.

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.

* It was found that the Linux kernel's Infiniband subsystem did not
properly sanitize input parameters while registering memory regions
from user space via the (u)verbs API. A local user with access to a
/dev/infiniband/uverbsX device could use this flaw to crash the system
or, potentially, escalate their privileges on the system.
(CVE-2014-8159, Important)

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* It was found that the parse_rock_ridge_inode_internal() function of
the Linux kernel's ISOFS implementation did not correctly check
relocated directories when processing Rock Ridge child link (CL) tags.
An attacker with physical access to the system could use a specially
crafted ISO image to crash the system or, potentially, escalate their
privileges on the system. (CVE-2014-5471, CVE-2014-5472, Low)

Red Hat would like to thank Mellanox for reporting the CVE-2014-8159
issue.

This update also fixes the following bugs :

* The kernel could sometimes panic due to a possible division by zero
in the kernel scheduler. This bug has been fixed by defining a new
div64_ul() division function and correcting the affected calculation
in the proc_sched_show_task() function. (BZ#1199898)

* When repeating a Coordinated Universal Time (UTC) value during a
leap second (when the UTC time should be 23:59:60), the International
Atomic Time (TAI) timescale previously stopped as the kernel NTP code
incremented the TAI offset one second too late. A patch has been
provided, which fixes the bug by incrementing the offset during the
leap second itself. Now, the correct TAI is set during the leap
second. (BZ#1201672)

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."

"  - An integer overflow flaw was found in the way the Linux
    kernel's Frame Buffer device implementation mapped
    kernel memory to user space via the mmap syscall. A
    local user able to access a frame buffer device file
    (/dev/fb*) could possibly use this flaw to escalate
    their privileges on the system. (CVE-2013-2596,
    Important)

  - It was found that the Xen hypervisor x86 CPU emulator
    implementation did not correctly handle certain
    instructions with segment overrides, potentially
    resulting in a memory corruption. A malicious guest user
    could use this flaw to read arbitrary data relating to
    other guests, cause a denial of service on the host, or
    potentially escalate their privileges on the host.
    (CVE-2015-2151, Important)

This update also fixes the following bugs :

  - Previously, the CPU power of a CPU group could be zero.
    As a consequence, a kernel panic occurred at
    'find_busiest_group+570' with do_divide_error. The
    provided patch ensures that the division is only
    performed if the CPU power is not zero, and the
    aforementioned panic no longer occurs.

  - Prior to this update, a bug occurred when performing an
    online resize of an ext4 file system which had been
    previously converted from ext3. As a consequence, the
    kernel crashed. The provided patch fixes online resizing
    for such file systems by limiting the blockgroup search
    loop for non- extent files, and the mentioned kernel
    crash no longer occurs.

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

"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 6. This is the sixth regular update.

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 NULL pointer dereference flaw was found in the way the Linux
kernel's Stream Control Transmission Protocol (SCTP) implementation
handled simultaneous connections between the same hosts. A remote
attacker could use this flaw to crash the system. (CVE-2014-5077,
Important)

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* A flaw was found in the way the ipc_rcu_putref() function in the
Linux kernel's IPC implementation handled reference counter
decrementing. A local, unprivileged user could use this flaw to
trigger an Out of Memory (OOM) condition and, potentially, crash the
system. (CVE-2013-4483, Moderate)

* It was found that the permission checks performed by the Linux
kernel when a netlink message was received were not sufficient. A
local, unprivileged user could potentially bypass these restrictions
by passing a netlink socket as stdout or stderr to a more privileged
process and altering the output of this process. (CVE-2014-0181,
Moderate)

* It was found that the try_to_unmap_cluster() function in the Linux
kernel's Memory Managment subsystem did not properly handle page
locking in certain cases, which could potentially trigger the BUG_ON()
macro in the mlock_vma_page() function. A local, unprivileged user
could use this flaw to crash the system. (CVE-2014-3122, Moderate)

* A flaw was found in the way the Linux kernel's kvm_iommu_map_pages()
function handled IOMMU mapping failures. A privileged user in a guest
with an assigned host device could use this flaw to crash the host.
(CVE-2014-3601, Moderate)

* Multiple use-after-free flaws were found in the way the Linux
kernel's Advanced Linux Sound Architecture (ALSA) implementation
handled user controls. A local, privileged user could use either of
these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654,
CVE-2014-4655, Moderate)

* A flaw was found in the way the Linux kernel's VFS subsystem handled
reference counting when performing unmount operations on symbolic
links. A local, unprivileged user could use this flaw to exhaust all
available memory on the system or, potentially, trigger a
use-after-free error, resulting in a system crash or privilege
escalation. (CVE-2014-5045, Moderate)

* An integer overflow flaw was found in the way the
lzo1x_decompress_safe() function of the Linux kernel's LZO
implementation processed Literal Runs. A local attacker could, in
extremely rare cases, use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2014-4608,
Low)

Red Hat would like to thank Vladimir Davydov of Parallels for
reporting CVE-2013-4483, Jack Morgenstein of Mellanox for reporting
CVE-2014-3601, Vasily Averin of Parallels for reporting CVE-2014-5045,
and Don A. Bailey from Lab Mouse Security for reporting CVE-2014-4608.
The security impact of the CVE-2014-3601 issue was discovered by
Michael Tsirkin of Red Hat.

This update also fixes several hundred bugs and adds numerous
enhancements. Refer to the Red Hat Enterprise Linux 6.6 Release Notes
for information on the most significant of these changes, and the
Technical Notes for further information, both linked to in the
References.

All Red Hat Enterprise Linux 6 users are advised to install these
updated packages, which correct these issues, and fix the bugs and add
the enhancements noted in the Red Hat Enterprise Linux 6.6 Release
Notes and Technical Notes. The system must be rebooted for this update
to take effect."

"From Red Hat Security Advisory 2014:1392 :

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 6. This is the sixth regular update.

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 NULL pointer dereference flaw was found in the way the Linux
kernel's Stream Control Transmission Protocol (SCTP) implementation
handled simultaneous connections between the same hosts. A remote
attacker could use this flaw to crash the system. (CVE-2014-5077,
Important)

* An integer overflow flaw was found in the way the Linux kernel's
Frame Buffer device implementation mapped kernel memory to user space
via the mmap syscall. A local user able to access a frame buffer
device file (/dev/fb*) could possibly use this flaw to escalate their
privileges on the system. (CVE-2013-2596, Important)

* A flaw was found in the way the ipc_rcu_putref() function in the
Linux kernel's IPC implementation handled reference counter
decrementing. A local, unprivileged user could use this flaw to
trigger an Out of Memory (OOM) condition and, potentially, crash the
system. (CVE-2013-4483, Moderate)

* It was found that the permission checks performed by the Linux
kernel when a netlink message was received were not sufficient. A
local, unprivileged user could potentially bypass these restrictions
by passing a netlink socket as stdout or stderr to a more privileged
process and altering the output of this process. (CVE-2014-0181,
Moderate)

* It was found that the try_to_unmap_cluster() function in the Linux
kernel's Memory Managment subsystem did not properly handle page
locking in certain cases, which could potentially trigger the BUG_ON()
macro in the mlock_vma_page() function. A local, unprivileged user
could use this flaw to crash the system. (CVE-2014-3122, Moderate)

* A flaw was found in the way the Linux kernel's kvm_iommu_map_pages()
function handled IOMMU mapping failures. A privileged user in a guest
with an assigned host device could use this flaw to crash the host.
(CVE-2014-3601, Moderate)

* Multiple use-after-free flaws were found in the way the Linux
kernel's Advanced Linux Sound Architecture (ALSA) implementation
handled user controls. A local, privileged user could use either of
these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654,
CVE-2014-4655, Moderate)

* A flaw was found in the way the Linux kernel's VFS subsystem handled
reference counting when performing unmount operations on symbolic
links. A local, unprivileged user could use this flaw to exhaust all
available memory on the system or, potentially, trigger a
use-after-free error, resulting in a system crash or privilege
escalation. (CVE-2014-5045, Moderate)

* An integer overflow flaw was found in the way the
lzo1x_decompress_safe() function of the Linux kernel's LZO
implementation processed Literal Runs. A local attacker could, in
extremely rare cases, use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2014-4608,
Low)

Red Hat would like to thank Vladimir Davydov of Parallels for
reporting CVE-2013-4483, Jack Morgenstein of Mellanox for reporting
CVE-2014-3601, Vasily Averin of Parallels for reporting CVE-2014-5045,
and Don A. Bailey from Lab Mouse Security for reporting CVE-2014-4608.
The security impact of the CVE-2014-3601 issue was discovered by
Michael Tsirkin of Red Hat.

This update also fixes several hundred bugs and adds numerous
enhancements. Refer to the Red Hat Enterprise Linux 6.6 Release Notes
for information on the most significant of these changes, and the
Technical Notes for further information, both linked to in the
References.

All Red Hat Enterprise Linux 6 users are advised to install these
updated packages, which correct these issues, and fix the bugs and add
the enhancements noted in the Red Hat Enterprise Linux 6.6 Release
Notes and Technical Notes. The system must be rebooted for this update
to take effect."

Moderate)

* It was found that the try_to_unmap_cluster() function in the Linux
kernel's Memory Managment subsystem did not properly handle page
locking in certain cases, which could potentially trigger the BUG_ON()
macro in the mlock_vma_page() function. A local, unprivileged user
could use this flaw to crash the system. (CVE-2014-3122, Moderate)

* A flaw was found in the way the Linux kernel's kvm_iommu_map_pages()
function handled IOMMU mapping failures. A privileged user in a guest
with an assigned host device could use this flaw to crash the host.
(CVE-2014-3601, Moderate)

* Multiple use-after-free flaws were found in the way the Linux
kernel's Advanced Linux Sound Architecture (ALSA) implementation
handled user controls. A local, privileged user could use either of
these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654,
CVE-2014-4655, Moderate)

* A flaw was found in the way the Linux kernel's VFS subsystem handled
reference counting when performing unmount operations on symbolic
links. A local, unprivileged user could use this flaw to exhaust all
available memory on the system or, potentially, trigger a
use-after-free error, resulting in a system crash or privilege
escalation. (CVE-2014-5045, Moderate)

* An integer overflow flaw was found in the way the
lzo1x_decompress_safe() function of the Linux kernel's LZO
implementation processed Literal Runs. A local attacker could, in
extremely rare cases, use this flaw to crash the system or,
potentially, escalate their privileges on the system. (CVE-2014-4608,
Low)
