According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel's ext4 filesystem     code. A use-after-free is possible in     ext4_ext_remove_space() function when mounting and     operating a crafted ext4 image.(CVE-2018-10876)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound write in the     fs/jbd2/transaction.c code, a denial of service, and a     system crash by unmounting a crafted ext4 filesystem     image.(CVE-2018-10882)

  - A use-after-free vulnerability was found in the way the     Linux kernel's KVM hypervisor emulates a preemption     timer for L2 guests when nested (=1) virtualization is     enabled. This high resolution timer(hrtimer) runs when     a L2 guest is active. After VM exit, the sync_vmcs12()     timer object is stopped. The use-after-free occurs if     the timer object is freed before calling sync_vmcs12()     routine. A guest user/process could use this flaw to     crash the host kernel resulting in a denial of service     or, potentially, gain privileged access to a     system.(CVE-2019-7221)

  - A flaw was found in the Linux kernel in the function     hso_probe() which reads if_num value from the USB     device (as an u8) and uses it without a length check to     index an array, resulting in an OOB memory read in     hso_probe() or hso_get_config_data(). An attacker with     a forged USB device and physical access to a system     (needed to connect such a device) can cause a system     crash and a denial of service.(CVE-2018-19985)

  - A possible memory corruption due to a type confusion     was found in the Linux kernel in the sk_clone_lock()     function in the net/core/sock.c. The possibility of     local escalation of privileges cannot be fully ruled     out for a local unprivileged attacker.(CVE-2018-9568)

  - A flaw was found in the Linux kernels implementation of     Logical link control and adaptation protocol (L2CAP),     part of the Bluetooth stack. An attacker with physical     access within the range of standard Bluetooth     transmission can create a specially crafted packet. The     response to this specially crafted packet can contain     part of the kernel stack which can be used in a further     attack.(CVE-2019-3459)

  - A flaw was found in the Linux kernel's implementation     of logical link control and adaptation protocol     (L2CAP), part of the Bluetooth stack in the     l2cap_parse_conf_rsp and l2cap_parse_conf_req     functions. An attacker with physical access within the     range of standard Bluetooth transmission can create a     specially crafted packet. The response to this     specially crafted packet can contain part of the kernel     stack which can be used in a further     attack.(CVE-2019-3460)

  - A flaw was found in mmap in the Linux kernel allowing     the process to map a null page. This allows attackers     to abuse this mechanism to turn null pointer     dereferences into workable exploits(CVE-2019-9213)

  - A new software page cache side channel attack scenario     was discovered in operating systems that implement the     very common 'page cache' caching mechanism. A malicious     user/process could use 'in memory' page-cache knowledge     to infer access timings to shared memory and gain     knowledge which can be used to reduce effectiveness of     cryptographic strength by monitoring algorithmic     behavior, infer access patterns of memory to determine     code paths taken, and exfiltrate data to a blinded     attacker through page-granularity access times as a     side-channel.(CVE-2019-5489)

  - A security flaw was found in the Linux kernel in a way     that the cleancache subsystem clears an inode after the     final file truncation (removal). The new file created     with the same inode may contain leftover pages from     cleancache and the old file data instead of the new     one.(CVE-2018-16862)

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2018-14625

A use-after-free bug was found in the vhost driver for the Virtual Socket protocol. If this driver is used to communicate with a malicious virtual machine guest, the guest could read sensitive information from the host kernel.

CVE-2018-16884

A flaw was found in the NFS 4.1 client implementation. Mounting NFS shares in multiple network namespaces at the same time could lead to a user-after-free. Local users might be able to use this for denial of service (memory corruption or crash) or possibly for privilege escalation.

This can be mitigated by disabling unprivileged users from creating user namespaces, which is the default in Debian.

CVE-2018-19824

Hui Peng and Mathias Payer discovered a use-after-free bug in the USB audio driver. A physically present attacker able to attach a specially designed USB device could use this for privilege escalation.

CVE-2018-19985

Hui Peng and Mathias Payer discovered a missing bounds check in the hso USB serial driver. A physically present user able to attach a specially designed USB device could use this to read sensitive information from the kernel or to cause a denial of service (crash).

CVE-2018-20169

Hui Peng and Mathias Payer discovered missing bounds checks in the USB core. A physically present attacker able to attach a specially designed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation.

CVE-2018-1000026

It was discovered that Linux could forward aggregated network packets with a segmentation size too large for the output device. In the specific case of Broadcom NetXtremeII 10Gb adapters, this would result in a denial of service (firmware crash). This update adds a mitigation to the bnx2x driver for this hardware.

CVE-2019-3459, CVE-2019-3460

Shlomi Oberman, Yuli Shapiro and Karamba Security Ltd. research team discovered missing range checks in the Bluetooth L2CAP implementation.
If Bluetooth is enabled, a nearby attacker could use these to read sensitive information from the kernel.

CVE-2019-3701

Muyu Yu and Marcus Meissner reported that the CAN gateway implementation allowed the frame length to be modified, typically resulting in out-of-bounds memory-mapped I/O writes. On a system with CAN devices present, a local user with CAP_NET_ADMIN capability in the initial net namespace could use this to cause a crash (oops) or other hardware-dependent impact.

CVE-2019-3819

A potential infinite loop was discovered in the HID debugfs interface exposed under /sys/kernel/debug/hid. A user with access to these files could use this for denial of service.

This interface is only accessible to root by default, which fully mitigates the issue.

CVE-2019-6974

Jann Horn reported a use-after-free bug in KVM. A local user with access to /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-7221

Jim Mattson and Felix Wilhelm reported a user-after-free bug in KVM's nested VMX implementation. On systems with Intel CPUs, a local user with access to /dev/kvm could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

Nested VMX is disabled by default, which fully mitigates the issue.

CVE-2019-7222

Felix Wilhelm reported an information leak in KVM for x86. A local user with access to /dev/kvm could use this to read sensitive information from the kernel.

CVE-2019-8980

A bug was discovered in the kernel_read_file() function used to load firmware files. In certain error conditions it could leak memory, which might lead to a denial of service. This is probbaly not exploitable in a Debian system.

CVE-2019-9213

Jann Horn reported that privileged tasks could cause stack segments, including those in other processes, to grow downward to address 0. On systems lacking SMAP (x86) or PAN (ARM), this exacerbated other vulnerabilities: a NULL pointer dereference could be exploited for privilege escalation rather than only for denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.168-1~deb8u1. This version also includes fixes for Debian bugs #904385, #918103, and #922306; and other fixes included in upstream stable updates.

We recommend that you upgrade your linux-4.9 and linux-latest-4.9 packages. You will need to use 'apt-get upgrade --with-new-pkgs' or 'apt upgrade' as the binary package names have changed.

    It was discovered that the USB serial device driver in the Linux kernel did not properly validate baud     rate settings when debugging is enabled. A local attacker could use this to cause a denial of service     (system crash). (CVE-2017-18360)

    Mathias Payer and Hui Peng discovered a use-after-free vulnerability in the Advanced Linux Sound     Architecture (ALSA) subsystem. A physically proximate attacker could use this to cause a denial of service     (system crash). (CVE-2018-19824)

    Shlomi Oberman, Yuli Shapiro, and Ran Menscher discovered an information leak in the Bluetooth     implementation of the Linux kernel. An attacker within Bluetooth range could use this to expose sensitive     information (kernel memory). (CVE-2019-3459, CVE-2019-3460)

    Jann Horn discovered that the KVM implementation in the Linux kernel contained a use-after-free     vulnerability. An attacker in a guest VM with access to /dev/kvm could use this to cause a denial of     service (guest VM crash). (CVE-2019-6974)

    Felix Wilhelm discovered that an information leak vulnerability existed in the KVM subsystem of the Linux     kernel, when nested virtualization is used. A local attacker could use this to expose sensitive     information (host system memory to a guest VM). (CVE-2019-7222)

    Jann Horn discovered that the mmap implementation in the Linux kernel did not properly check for the mmap     minimum address in some situations. A local attacker could use this to assist exploiting a kernel NULL     pointer dereference vulnerability. (CVE-2019-9213)

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.7 Release Notes linked from the References section.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the way Linux kernel KVM hypervisor     before 4.18 emulated instructions such as     sgdt/sidt/fxsave/fxrstor. It did not check current     privilege(CPL) level while emulating unprivileged     instructions. An unprivileged guest user/process could     use this flaw to potentially escalate privileges inside     guest. (CVE-2018-10853)

  - A flaw was found in the Linux Kernel where an attacker     may be able to have an uncontrolled read to kernel-     memory from within a vm guest. A race condition between     connect() and close() function may allow an attacker     using the AF_VSOCK protocol to gather a 4 byte     information leak or possibly intercept or corrupt     AF_VSOCK messages destined to other clients.
    (CVE-2018-14625)

  - drivers/infiniband/core/ucma.c in the Linux kernel     through 4.17.11 allows ucma_leave_multicast to access a     certain data structure after a cleanup step in     ucma_process_join, which allows attackers to cause a     denial of service (use-after-free). (CVE-2018-14734)

  - arch/x86/kernel/paravirt.c in the Linux kernel before     4.18.1 mishandles certain indirect calls, which makes it     easier for attackers to conduct Spectre-v2 attacks     against paravirtual guests. (CVE-2018-15594)

  - A flaw was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x up     to 4.20. An attacker, who is able to mount an exported     NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can     panic the machine and deny access to the NFS server. Any     outstanding disk writes to the NFS server will be lost.
    (CVE-2018-16871)

  - A flaw was found in the Linux kernel's NFS41+ subsystem.
    NFS41+ shares mounted in different network namespaces at     the same time can make bc_svc_process() use wrong back-     channel IDs and cause a use-after-free vulnerability.
    Thus a malicious container user can cause a host kernel     memory corruption and a system panic. Due to the nature     of the flaw, privilege escalation cannot be fully ruled     out. (CVE-2018-16884)

  - Since Linux kernel version 3.2, the mremap() syscall     performs TLB flushes after dropping pagetable locks. If     a syscall such as ftruncate() removes entries from the     pagetables of a task that is in the middle of mremap(),     a stale TLB entry can remain for a short time that     permits access to a physical page after it has been     released back to the page allocator and reused. This is     fixed in the following kernel versions: 4.9.135,     4.14.78, 4.18.16, 4.19. (CVE-2018-18281)

  - In the hidp_process_report in bluetooth, there is an     integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed.
    User interaction is not needed for exploitation.
    Product: Android Versions: Android kernel Android ID:
    A-65853588 References: Upstream kernel. (CVE-2018-9363)

  - In pppol2tp_connect, there is possible memory corruption     due to a use after free. This could lead to local     escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation.
    Product: Android. Versions: Android kernel. Android ID:
    A-38159931. (CVE-2018-9517)

  - Insufficient input validation in Kernel Mode Driver in     Intel(R) i915 Graphics for Linux before version 5.0 may     allow an authenticated user to potentially enable     escalation of privilege via local access.
    (CVE-2019-11085)

  - The coredump implementation in the Linux kernel before     5.0.10 does not use locking or other mechanisms to     prevent vma layout or vma flags changes while it runs,     which allows local users to obtain sensitive     information, cause a denial of service, or possibly have     unspecified other impact by triggering a race condition     with mmget_not_zero or get_task_mm calls. This is     related to fs/userfaultfd.c, mm/mmap.c,     fs/proc/task_mmu.c, and     drivers/infiniband/core/uverbs_main.c. (CVE-2019-11599)

  - An issue was discovered in the Linux kernel before     5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in     megasas_alloc_cmds() in     drivers/scsi/megaraid/megaraid_sas_base.c. This causes a     Denial of Service, related to a use-after-free.
    (CVE-2019-11810)

  - An issue was discovered in the Linux kernel before     5.0.4. There is a use-after-free upon attempted read     access to /proc/ioports after the ipmi_si module is     removed, related to drivers/char/ipmi/ipmi_si_intf.c,     drivers/char/ipmi/ipmi_si_mem_io.c, and     drivers/char/ipmi/ipmi_si_port_io.c. (CVE-2019-11811)

  - fs/ext4/extents.c in the Linux kernel through 5.1.2 does     not zero out the unused memory region in the extent tree     block, which might allow local users to obtain sensitive     information by reading uninitialized data in the     filesystem. (CVE-2019-11833)

  - A heap address information leak while using     L2CAP_GET_CONF_OPT was discovered in the Linux kernel     before 5.1-rc1. (CVE-2019-3459)

  - A heap data infoleak in multiple locations including     L2CAP_PARSE_CONF_RSP was found in the Linux kernel     before 5.1-rc1. (CVE-2019-3460)

  - A flaw was found in the Linux kernel's vfio interface     implementation that permits violation of the user's     locked memory limit. If a device is bound to a vfio     driver, such as vfio-pci, and the local attacker is     administratively granted ownership of the device, it may     cause a system memory exhaustion and thus a denial of     service (DoS). Versions 3.10, 4.14 and 4.18 are     vulnerable. (CVE-2019-3882)

  - An infinite loop issue was found in the vhost_net kernel     module in Linux Kernel up to and including v5.1-rc6,     while handling incoming packets in handle_rx(). It could     occur if one end sends packets faster than the other end     can process them. A guest user, maybe remote one, could     use this flaw to stall the vhost_net kernel thread,     resulting in a DoS scenario. (CVE-2019-3900)

  - The mincore() implementation in mm/mincore.c in the     Linux kernel through 4.19.13 allowed local attackers to     observe page cache access patterns of other processes on     the same system, potentially allowing sniffing of secret     information. (Fixing this affects the output of the     fincore program.) Limited remote exploitation may be     possible, as demonstrated by latency differences in     accessing public files from an Apache HTTP Server.
    (CVE-2019-5489)

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-20669: Missing access control checks in ioctl of gpu/drm/i915 driver were fixed which might have lead to information leaks.
(bnc#1122971).

CVE-2019-3459, CVE-2019-3460: The Bluetooth stack suffered from two remote information leak vulnerabilities in the code that handles incoming L2cap configuration packets (bsc#1120758).

CVE-2019-3819: A flaw was found in the function hid_debug_events_read() in drivers/hid/hid-debug.c file which may enter an infinite loop with certain parameters passed from a userspace. A local privileged user ('root') can cause a system lock up and a denial of service. (bnc#1123161).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bnc#1124728 ).

CVE-2019-7221: Fixed a use-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124732).

CVE-2019-7222: Fixed an information leakage in the KVM hypervisor related to handling page fault exceptions, which allowed a guest user/process to use this flaw to leak the host's stack memory contents to a guest (bsc#1124735).

CVE-2019-7308: kernel/bpf/verifier.c performed undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks (bnc#1124055).

CVE-2019-8912: af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr (bnc#1125907).

CVE-2019-8980: A memory leak in the kernel_read_file function in fs/exec.c allowed attackers to cause a denial of service (memory consumption) by triggering vfs_read failures (bnc#1126209).

CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).

CVE-2019-2024: A use-after-free when disconnecting a source was fixed which could lead to crashes. bnc#1129179).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.

Four new speculative execution information leak issues have been identified in Intel CPUs. (bsc#1111331)

CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)

CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)

CVE-2018-12130: Microarchitectural Load Port Data Samling (MLPDS)

CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM)

This kernel update contains software mitigations for these issues, which also utilize CPU microcode updates shipped in parallel.

For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736

The following security bugs were fixed: CVE-2016-10741:
fs/xfs/xfs_aops.c allowed local users to cause a denial of service (system crash) because there is a race condition between direct and memory-mapped I/O (associated with a hole) that is handled with BUG_ON instead of an I/O failure (bnc#1114920 bnc#1124010).

CVE-2017-1000407: By flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic (bnc#1071021).

CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674).

CVE-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c allowed physically proximate attackers to cause a denial of service (integer underflow) or possibly have unspecified other impact via a crafted HID report (bnc#1031240).

CVE-2017-7472: The KEYS subsystem allowed local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls (bnc#1034862).

CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.
Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target.
(bnc#1107829).

CVE-2018-15572: The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517 bnc#1105296).

CVE-2018-16884: NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bnc#1119946).

CVE-2018-18281: The mremap() syscall performed TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769).

CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).

CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025).

CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).

CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

CVE-2018-19985: The function hso_get_config_data in drivers/net/usb/hso.c read if_num from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds (OOB) read that potentially allowed arbitrary read in the kernel address space (bnc#1120743).

CVE-2018-20169: The USB subsystem mishandled size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c (bnc#1119714).

CVE-2018-5391: The Linux kernel was vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size (bnc#1103097).

CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check.
This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
(bnc#1108498).

CVE-2018-9568: In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (bnc#1118319).

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c had multiple race conditions (bnc#1133188). The line discipline was disabled.

CVE-2019-3459: A heap address information leak while using L2CAP_GET_CONF_OPT was discovered (bnc#1120758).

CVE-2019-3460: A heap data infoleak in multiple locations including L2CAP_PARSE_CONF_RSP was found (bnc#1120758).

CVE-2019-3882: A flaw was found vfio interface implementation that permitted violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS).
(bnc#1131416 bnc#1131427).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, leading to a use-after-free (bnc#1124728).

CVE-2019-7221: The KVM implementation had a Use-after-Free (bnc#1124732).

CVE-2019-7222: The KVM implementation had an Information Leak (bnc#1124735).

CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).

CVE-2019-9503: Multiple brcmfmac frame validation bypasses have been fixed (bnc#1132828).

The update package also includes non-security fixes. See advisory for details.
