"This update fixes the following security issue :

  - A flaw was found in the way the Xen hypervisor AMD IOMMU
    driver handled interrupt remapping entries. By default,
    a single interrupt remapping table is used, and old
    interrupt remapping entries are not cleared, potentially
    allowing a privileged guest user in a guest that has a
    passed- through, bus-mastering capable PCI device to
    inject interrupt entries into others guests, including
    the privileged management domain (Dom0), leading to a
    denial of service. (CVE-2013-0153, Moderate)

This update also fixes the following bugs :

  - When a process is opening a file over NFSv4, sometimes
    an OPEN call can succeed while the following GETATTR
    operation fails with an NFS4ERR_DELAY error. The NFSv4
    code did not handle such a situation correctly and
    allowed an NFSv4 client to attempt to use the buffer
    that should contain the GETATTR information. However,
    the buffer did not contain the valid GETATTR
    information, which caused the client to return a
    '-ENOTDIR' error. Consequently, the process failed to
    open the requested file. This update backports a patch
    that adds a test condition verifying validity of the
    GETATTR information. If the GETATTR information is
    invalid, it is obtained later and the process opens the
    requested file as expected.

  - Previously, the xdr routines in NFS version 2 and 3
    conditionally updated the res->count variable. Read
    retry attempts after a short NFS read() call could fail
    to update the res->count variable, resulting in
    truncated read data being returned. With this update,
    the res->count variable is updated unconditionally so
    this bug can no longer occur.

  - When handling requests from Intelligent Platform
    Management Interface (IPMI) clients, the IPMI driver
    previously used two different locks for an IPMI request.
    If two IPMI clients sent their requests at the same
    time, each request could receive one of the locks and
    then wait for the second lock to become available. This
    resulted in a deadlock situation and the system became
    unresponsive. The problem could occur more likely in
    environments with many IPMI clients. This update
    modifies the IPMI driver to handle the received messages
    using tasklets so the driver now uses a safe locking
    technique when handling IPMI requests and the mentioned
    deadlock can no longer occur.

  - Incorrect locking around the cl_state_owners list could
    cause the NFSv4 state reclaimer thread to enter an
    infinite loop while holding the Big Kernel Lock (BLK).
    As a consequence, the NFSv4 client became unresponsive.
    With this update, safe list iteration is used, which
    prevents the NFSv4 client from hanging in this scenario.

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

"Updated kernel packages that fix one security issue and multiple bugs
are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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

This update fixes the following security issue :

* A flaw was found in the way the Xen hypervisor AMD IOMMU driver
handled interrupt remapping entries. By default, a single interrupt
remapping table is used, and old interrupt remapping entries are not

Red Hat would like to thank the Xen project for reporting the
CVE-2013-0153 issue.

"The SUSE Linux Enterprise Server 11 Service Pack 1 LTSS Xen hypervisor
and toolset have been updated to fix various security issues and some
bugs.

The following security issues have been addressed :

XSA-84: CVE-2014-1894: Xen 3.2 (and presumably earlier) exhibit both
problems with the overflow issue being present for more than just the
suboperations listed above. (bnc#860163)

XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through 4.1,
while not affected by the above overflow, have a different
overflow issue on FLASK_{GET,SET}BOOL and expose
unreasonably large memory allocation to arbitrary guests.
(bnc#860163)

XSA-84: CVE-2014-1891: The FLASK_{GET,SET}BOOL, FLASK_USER
and FLASK_CONTEXT_TO_SID suboperations of the flask
hypercall are vulnerable to an integer overflow on the input
size. The hypercalls attempt to allocate a buffer which is 1
larger than this size and is therefore vulnerable to integer
overflow and an attempt to allocate then access a zero byte
buffer. (bnc#860163)

XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h through
0Fh processors does not properly handle the interaction
between locked instructions and write-combined memory types,
which allows local users to cause a denial of service
(system hang) via a crafted application, aka the errata 793
issue. (bnc#853049)

XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x (possibly
4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x (possibly 4.3.1)
does not properly prevent access to hypercalls, which allows
local guest users to gain privileges via a crafted
application running in ring 1 or 2. (bnc#849668)

XSA-74: CVE-2013-4553: The XEN_DOMCTL_getmemlist hypercall
in Xen 3.4.x through 4.3.x (possibly 4.3.1) does not always
obtain the page_alloc_lock and mm_rwlock in the same order,
which allows local guest administrators to cause a denial of
service (host deadlock). (bnc#849667)

XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and 4.3.x
does not take the page_alloc_lock and grant_table.lock in
the same order, which allows local guest administrators with
access to multiple vcpus to cause a denial of service (host
deadlock) via unspecified vectors. (bnc#848657)

XSA-67: CVE-2013-4368: The outs instruction emulation in Xen
3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS:
segment override, uses an uninitialized variable as a
segment base, which allows local 64-bit PV guests to obtain
sensitive information (hypervisor stack content) via
unspecified vectors related to stale data in a segment
register. (bnc#842511)

XSA-66: CVE-2013-4361: The fbld instruction emulation in Xen
3.3.x through 4.3.x does not use the correct variable for
the source effective address, which allows local HVM guests
to obtain hypervisor stack information by reading the values
used by the instruction. (bnc#841766)

XSA-63: CVE-2013-4355: Xen 4.3.x and earlier does not
properly handle certain errors, which allows local HVM
guests to obtain hypervisor stack memory via a (1) port or
(2) memory mapped I/O write or (3) other unspecified
operations related to addresses without associated memory.
(bnc#840592)

XSA-62: CVE-2013-1442: Xen 4.0 through 4.3.x, when using AVX
or LWP capable CPUs, does not properly clear previous data
from registers when using an XSAVE or XRSTOR to extend the
state components of a saved or restored vCPU after touching
other restored extended registers, which allows local guest
OSes to obtain sensitive information by reading the
registers. (bnc#839596)

XSA-61: CVE-2013-4329: The xenlight library (libxl) in Xen
4.0.x through 4.2.x, when IOMMU is disabled, provides access
to a busmastering-capable PCI passthrough device before the
IOMMU setup is complete, which allows local HVM guest
domains to gain privileges or cause a denial of service via
a DMA instruction. (bnc#839618)

XSA-60: CVE-2013-2212: The vmx_set_uc_mode function in Xen
3.3 through 4.3, when disabling chaches, allows local HVM
guests with access to memory mapped I/O regions to cause a
denial of service (CPU consumption and possibly hypervisor
or guest kernel panic) via a crafted GFN range. (bnc#831120)

XSA-58: CVE-2013-1918: Certain page table manipulation
operations in Xen 4.1.x, 4.2.x, and earlier are not
preemptible, which allows local PV kernels to cause a denial
of service via vectors related to 'deep page table
traversal.' (bnc#826882)

XSA-58: CVE-2013-1432: Xen 4.1.x and 4.2.x, when the XSA-45
patch is in place, does not properly maintain references on
pages stored for deferred cleanup, which allows local PV
guest kernels to cause a denial of service (premature page
free and hypervisor crash) or possible gain privileges via
unspecified vectors. (bnc#826882)

XSA-57: CVE-2013-2211: The libxenlight (libxl) toolstack
library in Xen 4.0.x, 4.1.x, and 4.2.x uses weak permissions
for xenstore keys for paravirtualised and emulated serial
console devices, which allows local guest administrators to
modify the xenstore value via unspecified vectors.
(bnc#823608)

XSA-56: CVE-2013-2072: Buffer overflow in the Python
bindings for the xc_vcpu_setaffinity call in Xen 4.0.x,
4.1.x, and 4.2.x allows local administrators with
permissions to configure VCPU affinity to cause a denial of
service (memory corruption and xend toolstack crash) and
possibly gain privileges via a crafted cpumap. (bnc#819416)

XSA-55: CVE-2013-2196: Multiple unspecified vulnerabilities
in the Elf parser (libelf) in Xen 4.2.x and earlier allow
local guest administrators with certain permissions to have
an unspecified impact via a crafted kernel, related to
'other problems' that are not CVE-2013-2194 or
CVE-2013-2195. (bnc#823011)

XSA-55: CVE-2013-2195: The Elf parser (libelf) in Xen 4.2.x
and earlier allow local guest administrators with certain
permissions to have an unspecified impact via a crafted
kernel, related to 'pointer dereferences' involving
unexpected calculations. (bnc#823011)

XSA-55: CVE-2013-2194: Multiple integer overflows in the Elf
parser (libelf) in Xen 4.2.x and earlier allow local guest
administrators with certain permissions to have an
unspecified impact via a crafted kernel. (bnc#823011)

XSA-53: CVE-2013-2077: Xen 4.0.x, 4.1.x, and 4.2.x does not
properly restrict the contents of a XRSTOR, which allows
local PV guest users to cause a denial of service (unhandled
exception and hypervisor crash) via unspecified vectors.
(bnc#820919)

XSA-52: CVE-2013-2076: Xen 4.0.x, 4.1.x, and 4.2.x, when
running on AMD64 processors, only save/restore the FOP, FIP,
and FDP x87 registers in FXSAVE/FXRSTOR when an exception is
pending, which allows one domain to determine portions of
the state of floating point instructions of other domains,
which can be leveraged to obtain sensitive information such
as cryptographic keys, a similar vulnerability to
CVE-2006-1056. NOTE: this is the documented behavior of
AMD64 processors, but it is inconsistent with Intel
processors in a security-relevant fashion that was not
addressed by the kernels. (bnc#820917)

XSA-50: CVE-2013-1964: Xen 4.0.x and 4.1.x incorrectly
releases a grant reference when releasing a non-v1,
non-transitive grant, which allows local guest
administrators to cause a denial of service (host crash),
obtain sensitive information, or possible have other impacts
via unspecified vectors. (bnc#816156)

XSA-49: CVE-2013-1952: Xen 4.x, when using Intel VT-d for a
bus mastering capable PCI device, does not properly check
the source when accessing a bridge device's interrupt
remapping table entries for MSI interrupts, which allows
local guest domains to cause a denial of service (interrupt
injection) via unspecified vectors. (bnc#816163)

XSA-47: CVE-2013-1920: Xen 4.2.x, 4.1.x, and earlier, when
the hypervisor is running 'under memory pressure' and the
Xen Security Module (XSM) is enabled, uses the wrong
ordering of operations when extending the per-domain event
channel tracking table, which causes a use-after-free and
allows local guest kernels to inject arbitrary events and
gain privileges via unspecified vectors. (bnc#813677)

XSA-46: CVE-2013-1919: Xen 4.2.x and 4.1.x does not properly
restrict access to IRQs, which allows local stub domain
clients to gain access to IRQs and cause a denial of service
via vectors related to 'passed-through IRQs or PCI devices.'
(bnc#813675)

XSA-45: CVE-2013-1918: Certain page table manipulation
operations in Xen 4.1.x, 4.2.x, and earlier are not
preemptible, which allows local PV kernels to cause a denial
of service via vectors related to 'deep page table
traversal.' (bnc#816159)

XSA-44: CVE-2013-1917: Xen 3.1 through 4.x, when running
64-bit hosts on Intel CPUs, does not clear the NT flag when
using an IRET after a SYSENTER instruction, which allows PV
guest users to cause a denial of service (hypervisor crash)
by triggering a #GP fault, which is not properly handled by
another IRET instruction. (bnc#813673)

XSA-41: CVE-2012-6075: Buffer overflow in the e1000_receive
function in the e1000 device driver (hw/e1000.c) in QEMU
1.3.0-rc2 and other versions, when the SBP and LPE flags are
disabled, allows remote attackers to cause a denial of
service (guest OS crash) and possibly execute arbitrary
guest code via a large packet. (bnc#797523)

XSA-37: CVE-2013-0154: The get_page_type function in
xen/arch/x86/mm.c in Xen 4.2, when debugging is enabled,
allows local PV or HVM guest administrators to cause a
denial of service (assertion failure and hypervisor crash)
via unspecified vectors related to a hypercall. (bnc#797031)

XSA-36: CVE-2013-0153: The AMD IOMMU support in Xen 4.2.x,
4.1.x, 3.3, and other versions, when using AMD-Vi for PCI
passthrough, uses the same interrupt remapping table for the
host and all guests, which allows guests to cause a denial
of service by injecting an interrupt into other guests.
(bnc#800275)

XSA-33: CVE-2012-5634: Xen 4.2.x, 4.1.x, and 4.0, when using
Intel VT-d for PCI passthrough, does not properly configure
VT-d when supporting a device that is behind a legacy PCI
Bridge, which allows local guests to cause a denial of
service to other guests by injecting an interrupt.
(bnc#794316)

XSA-31: CVE-2012-5515: The (1) XENMEM_decrease_reservation,
(2) XENMEM_populate_physmap, and (3) XENMEM_exchange
hypercalls in Xen 4.2 and earlier allow local guest
administrators to cause a denial of service (long loop and
hang) via a crafted extent_order value. (bnc#789950)

XSA-30: CVE-2012-5514: The
guest_physmap_mark_populate_on_demand function in Xen 4.2
and earlier does not properly unlock the subject GFNs when
checking if they are in use, which allows local guest HVM
administrators to cause a denial of service (hang) via
unspecified vectors. (bnc#789948)

XSA-29: CVE-2012-5513: The XENMEM_exchange handler in Xen
4.2 and earlier does not properly check the memory address,
which allows local PV guest OS administrators to cause a
denial of service (crash) or possibly gain privileges via
unspecified vectors that overwrite memory in the hypervisor
reserved range. (bnc#789951)

XSA-27: CVE-2012-6333: Multiple HVM control operations in
Xen 3.4 through 4.2 allow local HVM guest OS administrators
to cause a denial of service (physical CPU consumption) via
a large input. (bnc#789944)

XSA-27: CVE-2012-5511: Stack-based buffer overflow in the
dirty video RAM tracking functionality in Xen 3.4 through
4.1 allows local HVM guest OS administrators to cause a
denial of service (crash) via a large bitmap image.
(bnc#789944)

XSA-26: CVE-2012-5510: Xen 4.x, when downgrading the grant
table version, does not properly remove the status page from
the tracking list when freeing the page, which allows local
guest OS administrators to cause a denial of service
(hypervisor crash) via unspecified vectors. (bnc#789945)

XSA-25: CVE-2012-4544: The PV domain builder in Xen 4.2 and
earlier does not validate the size of the kernel or ramdisk
(1) before or (2) after decompression, which allows local
guest administrators to cause a denial of service (domain 0
memory consumption) via a crafted (a) kernel or (b) ramdisk.
(bnc#787163)

XSA-24: CVE-2012-4539: Xen 4.0 through 4.2, when running
32-bit x86 PV guests on 64-bit hypervisors, allows local
guest OS administrators to cause a denial of service
(infinite loop and hang or crash) via invalid arguments to
GNTTABOP_get_status_frames, aka 'Grant table hypercall
infinite loop DoS vulnerability.' (bnc#786520)

XSA-23: CVE-2012-4538: The HVMOP_pagetable_dying hypercall
in Xen 4.0, 4.1, and 4.2 does not properly check the
pagetable state when running on shadow pagetables, which
allows a local HVM guest OS to cause a denial of service
(hypervisor crash) via unspecified vectors. (bnc#786519)

XSA-22: CVE-2012-4537: Xen 3.4 through 4.2, and possibly
earlier versions, does not properly synchronize the p2m and
m2p tables when the set_p2m_entry function fails, which
allows local HVM guest OS administrators to cause a denial
of service (memory consumption and assertion failure), aka
'Memory mapping failure DoS vulnerability.' (bnc#786517)

XSA-20: CVE-2012-4535: Xen 3.4 through 4.2, and possibly
earlier versions, allows local guest OS administrators to
cause a denial of service (Xen infinite loop and physical

    Multiple vulnerabilities have been discovered in Xen. Please review the
      CVE identifiers referenced below for details.
  
Impact :

    Guest domains could possibly gain privileges, execute arbitrary code, or
      cause a Denial of Service on the host domain (Dom0). Additionally, guest
      domains could gain information about other virtual machines running on
      the same host or read arbitrary files on the host.
  
Workaround :

    The CVEs listed below do not currently have fixes, but only apply to Xen
      setups which have “tmem” specified on the hypervisor command line.
      TMEM is not currently supported for use in production systems, and
      administrators using tmem should disable it.
      Relevant CVEs:
      * CVE-2012-2497

"Updated kernel packages that fix one security issue and multiple bugs
are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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

This update fixes the following security issue :

* A flaw was found in the way the Xen hypervisor AMD IOMMU driver
handled interrupt remapping entries. By default, a single interrupt
remapping table is used, and old interrupt remapping entries are not
cleared, potentially allowing a privileged guest user in a guest that
has a passed-through, bus-mastering capable PCI device to inject
interrupt entries into others guests, including the privileged
management domain (Dom0), leading to a denial of service.
(CVE-2013-0153, Moderate)

Red Hat would like to thank the Xen project for reporting the
CVE-2013-0153 issue.

This update also fixes the following bugs :

* When a process is opening a file over NFSv4, sometimes an OPEN call
can succeed while the following GETATTR operation fails with an
NFS4ERR_DELAY error. The NFSv4 code did not handle such a situation
correctly and allowed an NFSv4 client to attempt to use the buffer
that should contain the GETATTR information. However, the buffer did
not contain the valid GETATTR information, which caused the client to
return a '-ENOTDIR' error. Consequently, the process failed to open
the requested file. This update backports a patch that adds a test
condition verifying validity of the GETATTR information. If the
GETATTR information is invalid, it is obtained later and the process
opens the requested file as expected. (BZ#947736)

* Previously, the xdr routines in NFS version 2 and 3 conditionally
updated the res->count variable. Read retry attempts after a short NFS
read() call could fail to update the res->count variable, resulting in
truncated read data being returned. With this update, the res->count
variable is updated unconditionally so this bug can no longer occur.
(BZ#952098)

* When handling requests from Intelligent Platform Management
Interface (IPMI) clients, the IPMI driver previously used two
different locks for an IPMI request. If two IPMI clients sent their
requests at the same time, each request could receive one of the locks
and then wait for the second lock to become available. This resulted
in a deadlock situation and the system became unresponsive. The
problem could occur more likely in environments with many IPMI
clients. This update modifies the IPMI driver to handle the received
messages using tasklets so the driver now uses a safe locking
technique when handling IPMI requests and the mentioned deadlock can
no longer occur. (BZ#953435)

* Incorrect locking around the cl_state_owners list could cause the
NFSv4 state reclaimer thread to enter an infinite loop while holding
the Big Kernel Lock (BLK). As a consequence, the NFSv4 client became
unresponsive. With this update, safe list iteration is used, which
prevents the NFSv4 client from hanging in this scenario. (BZ#954296)

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

"From Red Hat Security Advisory 2013:0847 :

Updated kernel packages that fix one security issue and multiple bugs
are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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

This update fixes the following security issue :

* A flaw was found in the way the Xen hypervisor AMD IOMMU driver
handled interrupt remapping entries. By default, a single interrupt
remapping table is used, and old interrupt remapping entries are not
cleared, potentially allowing a privileged guest user in a guest that
has a passed-through, bus-mastering capable PCI device to inject
interrupt entries into others guests, including the privileged
management domain (Dom0), leading to a denial of service.
(CVE-2013-0153, Moderate)

Red Hat would like to thank the Xen project for reporting the
CVE-2013-0153 issue.

This update also fixes the following bugs :

* When a process is opening a file over NFSv4, sometimes an OPEN call
can succeed while the following GETATTR operation fails with an
NFS4ERR_DELAY error. The NFSv4 code did not handle such a situation
correctly and allowed an NFSv4 client to attempt to use the buffer
that should contain the GETATTR information. However, the buffer did
not contain the valid GETATTR information, which caused the client to
return a '-ENOTDIR' error. Consequently, the process failed to open
the requested file. This update backports a patch that adds a test
condition verifying validity of the GETATTR information. If the
GETATTR information is invalid, it is obtained later and the process
opens the requested file as expected. (BZ#947736)

* Previously, the xdr routines in NFS version 2 and 3 conditionally
updated the res->count variable. Read retry attempts after a short NFS
read() call could fail to update the res->count variable, resulting in
truncated read data being returned. With this update, the res->count
variable is updated unconditionally so this bug can no longer occur.
(BZ#952098)

* When handling requests from Intelligent Platform Management
Interface (IPMI) clients, the IPMI driver previously used two
different locks for an IPMI request. If two IPMI clients sent their
requests at the same time, each request could receive one of the locks
and then wait for the second lock to become available. This resulted
in a deadlock situation and the system became unresponsive. The
problem could occur more likely in environments with many IPMI
clients. This update modifies the IPMI driver to handle the received
messages using tasklets so the driver now uses a safe locking
technique when handling IPMI requests and the mentioned deadlock can
no longer occur. (BZ#953435)

* Incorrect locking around the cl_state_owners list could cause the
NFSv4 state reclaimer thread to enter an infinite loop while holding
the Big Kernel Lock (BLK). As a consequence, the NFSv4 client became
unresponsive. With this update, safe list iteration is used, which
prevents the NFSv4 client from hanging in this scenario. (BZ#954296)

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

    xsa38.patch The oxenstored daemon (the ocaml version of
    the xenstore daemon) does not correctly handle unusual

  - ACPI: acpi_table_parse should return handler's error
    code Currently, the error code returned by
    acpi_table_parse's handler is ignored. This patch will
    propagate handler's return value to acpi_table_parse's
    caller. AMD,IOMMU: Clean up old entries in remapping
    tables when creating new interrupt mapping. When
    changing the affinity of an IRQ associated with a passed
    through PCI device, clear previous mapping. In addition,
    because some BIOSes may incorrectly program IVRS entries
    for IOAPIC try to check for entry's consistency.
    Specifically, if conflicting entries are found disable
    IOMMU if per-device remapping table is used. If entries
    refer to bogus IOAPIC IDs disable IOMMU unconditionally
    AMD,IOMMU: Disable IOMMU if SATA Combined mode is on
    AMD's SP5100 chipset can be placed into SATA Combined
    mode that may cause prevent dom0 from booting when IOMMU
    is enabled and per-device interrupt remapping table is
    used. While SP5100 erratum 28 requires BIOSes to disable
    this mode, some may still use it. This patch checks
    whether this mode is on and, if per-device table is in
    use, disables IOMMU. AMD,IOMMU: Make per-device
    interrupt remapping table default Using global interrupt
    remapping table may be insecure, as described by XSA-36.

    has been disabled for AMD chipsets not capable of it.
