The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - In the Linux kernel, Hisilicon Network Subsystem (HNS)     does not consider the ETH_SS_PRIV_FLAGS case when     retrieving sset_count data. This allows local users to     cause a denial of service (buffer overflow and memory     corruption) or possibly have unspecified other     impacts.(CVE-2017-18222i1/4%0

  - A flaw was found in the way the Linux kernel's     networking implementation handled UDP packets with     incorrect checksum values. A remote attacker could     potentially use this flaw to trigger an infinite loop     in the kernel, resulting in a denial of service on the     system, or cause a denial of service in applications     using the edge triggered epoll     functionality.(CVE-2015-5366i1/4%0

  - A use-after-free vulnerability was found in the     kernel's socket recvmmsg subsystem. This may allow     remote attackers to corrupt memory and may allow     execution of arbitrary code. This corruption takes     place during the error handling routines within
    __sys_recvmmsg() function.(CVE-2016-7117i1/4%0

  - arch/x86/kvm/vmx.c in the Linux kernel through 4.6.3     mishandles the APICv on/off state, which allows guest     OS users to obtain direct APIC MSR access on the host     OS, and consequently cause a denial of service (host OS     crash) or possibly execute arbitrary code on the host     OS, via x2APIC mode.(CVE-2016-4440i1/4%0

  - In the Linux kernel before 4.17, 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 mishandles ATTR_REPLACE     operations with conversion of an attr from short to     long form.(CVE-2018-18690i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bounds write and a     denial of service or unspecified other impact is     possible by mounting and operating a crafted ext4     filesystem image.(CVE-2018-10878i1/4%0

  - Xen 3.3.x through 4.5.x and the Linux kernel through     3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to     cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O     decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR)     response.(CVE-2015-2150i1/4%0

  - The assoc_array_insert_into_terminal_node() function in     'lib/assoc_array.c' in the Linux kernel before 4.5.3     does not check whether a slot is a leaf, which allows     local users to obtain sensitive information from kernel     memory or cause a denial of service (invalid pointer     dereference and out-of-bounds read) via an application     that uses associative-array data     structures.(CVE-2016-7914i1/4%0

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #AC (alignment check exception) is handled. A     privileged user inside a guest could use this flaw to     create denial of service conditions on the host     kernel.(CVE-2015-5307i1/4%0

  - An issue was discovered in fs/f2fs/super.c in the Linux     kernel, which does not properly validate secs_per_zone     in a corrupted f2fs image. This may lead to a     divide-by-zero error and a system     crash.(CVE-2018-13100i1/4%0

  - The mISDN_sock_recvmsg function in     drivers/isdn/mISDN/socket.c in the Linux kernel before     3.12.4 does not ensure that a certain length value is     consistent with the size of an associated data     structure, which allows local users to obtain sensitive     information from kernel memory via a (1) recvfrom, (2)     recvmmsg, or (3) recvmsg system call.(CVE-2013-7266i1/4%0

  - A NULL pointer dereference flaw was found in the     rds_iw_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-2678i1/4%0

  - A flaw was found in the Linux kernel's handling of     packets with the URG flag. Applications using the     splice() and tcp_splice_read() functionality could     allow a remote attacker to force the kernel to enter a     condition in which it could loop     indefinitely.(CVE-2017-6214i1/4%0

  - The kernel_wait4 function in kernel/exit.c in the Linux     kernel before 4.13, when an unspecified architecture     and compiler is used, might allow local users to cause     a denial of service by triggering an attempted use of     the -INT_MIN value.(CVE-2018-10087i1/4%0

  - Heap-based buffer overflow in the private wireless     extensions IOCTL implementation in wlan_hdd_wext.c in     the WLAN (aka Wi-Fi) driver for the Linux kernel 3.x     and 4.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, allows attackers to gain privileges via a     crafted application that establishes a packet     filter.(CVE-2015-0569i1/4%0

  - 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-2014-8086i1/4%0

  - The mm_init function in kernel/fork.c in the Linux     kernel before 4.12.10 does not clear the -i1/4zexe_file     member of a new process's mm_struct, allowing a local     attacker to achieve a use-after-free condition and to     induce a kernel memory corruption on the system,     leading to a crash or possibly have unspecified other     impact by running a specially crafted program. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although we feel it is     unlikely.(CVE-2017-17052i1/4%0

  - A buffer overflow flaw was found in the way the Linux     kernel's Intel AES-NI instructions optimized version of     the RFC4106 GCM mode decryption functionality handled     fragmented packets. A remote attacker could use this     flaw to crash, or potentially escalate their privileges     on, a system over a connection with an active AES-GCM     mode IPSec security association.(CVE-2015-3331i1/4%0

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can     be sent to an attacker leaking data in kernel address     space.(CVE-2017-1000410i1/4%0

  - It was found that a remote attacker could use a race     condition flaw in the ath_tx_aggr_sleep() function to     crash the system by creating large network traffic on     the system's Atheros 9k wireless network     adapter.(CVE-2014-2672i1/4%0

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.4 Extended 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 use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter.
A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important)

* A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2013-7339, Moderate)

* It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate)

* A NULL pointer dereference flaw was found in the rds_iw_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2014-2678, Moderate)

* A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate)

This update also fixes the following bugs :

* The Completely Fair Scheduler (CFS) did not verify whether the CFS period timer is running while throttling tasks on the CFS run queue.
Therefore under certain circumstances, the CFS run queue became stuck because the CFS period timer was inactive and could not be restarted.
To fix this problem, the CFS now restarts the CFS period timer inside the throttling function if it is inactive. (BZ#1120666)

* A previous change to the SCSI code fixed a race condition that could occur when removing a SCSI device. However, that change caused performance degradation because it used a certain function from the block layer code that was returning different values compared with later versions of the kernel. This update alters the SCSI code to properly utilize the values returned by the block layer code.
(BZ#1117581)

* If a statically defined gateway became unreachable and its corresponding neighbor entry entered a FAILED state, the gateway stayed in the FAILED state even after it became reachable again. This prevented routing of the traffic through that gateway. This update allows probing such a gateway automatically and routing the traffic through the gateway again once it becomes reachable. (BZ#1115262)

* A miscalculation in the 'radix_tree' swap encoding corrupted swap area indexes bigger than 8 by truncating lower bits of swap entries.
Consequently, systems with more than 8 swap areas could trigger a bogus OOM scenario when swapping out to such a swap area. This update fixes this problem by reducing a return value of the SWP_TYPE_SHIFT() function and removing a broken function call from the read_swap_header() function. (BZ#1099727)

* The automatic route cache rebuilding feature could incorrectly compute the length of a route hash chain if the cache contained multiple entries with the same key but a different TOS, mark, or OIF bit. Consequently, the feature could reach the rebuild limit and disable the routing cache on the system. This problem is fixed by using a helper function that avoids counting such duplicate routes.
(BZ#1113823)

* When booting a guest in the Hyper-V environment and enough of Programmable Interval Timer (PIT) interrupts were lost or not injected into the guest on time, the kernel panicked and the guest failed to boot. This problem has been fixed by bypassing the relevant PIT check when the guest is running under the Hyper-V environment. (BZ#1112225)

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.

- A NULL pointer dereference flaw was found in the     rds_iw_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system. (CVE-2014-2678, Moderate)

  - It was found that the Xen hypervisor implementation did     not properly clean memory pages previously allocated by     the hypervisor. A privileged guest user could     potentially use this flaw to read data relating to other     guests or the hypervisor itself. (CVE-2014-4021,     Moderate)

This update also fixes the following bugs :

  - A bug in the journaling block device (jbd and jbd2) code     could, under certain circumstances, trigger a BUG_ON()     assertion and result in a kernel oops. This happened     when an application performed an extensive number of     commits to the journal of the ext3 file system and there     was no currently active transaction while synchronizing     the file's in-core state. This problem has been resolved     by correcting respective test conditions in the jbd and     jbd2 code.

  - After a statically defined gateway became unreachable     and its corresponding neighbor entry entered a FAILED     state, the gateway stayed in the FAILED state even after     it became reachable again. As a consequence, traffic was     not routed through that gateway. This update allows     probing such a gateway automatically so that the traffic     can be routed through this gateway again once it becomes     reachable.

  - Due to an incorrect condition check in the IPv6 code,     the ipv6 driver was unable to correctly assemble     incoming packet fragments, which resulted in a high IPv6     packet loss rate. This update fixes the said check for a     fragment overlap and ensures that incoming IPv6 packet     fragments are now processed as expected.

  - Recent changes in the d_splice_alias() function     introduced a bug that allowed d_splice_alias() to return     a dentry from a different directory than the directory     being looked up. As a consequence in cluster     environment, a kernel panic could be triggered when a     directory was being removed while a concurrent     cross-directory operation was performed on this     directory on another cluster node. This update avoids     the kernel panic in this situation by correcting the     search logic in the d_splice_alias() function so that     the function can no longer return a dentry from an     incorrect directory.

  - The NFSv4 server did not handle multiple OPEN operations     to the same file separately, which could cause the NFSv4     client to repeatedly send CLOSE requests with the same     state ID, even though the NFS server rejected the     request with an NFS4ERR_OLD_STATEID (10024) error code.
    This update ensures that the NFSv4 client no longer     re-sends the same CLOSE request after receiving     NFS4ERR_OLD_STATEID.

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

The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk (CVE-2014-0101).

The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer (CVE-2014-0069).

arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction (CVE-2014-2039).

Buffer overflow in virt/kvm/irq_comm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to Message Signaled Interrupts (MSI), irq routing entries, and an incorrect check by the setup_routing_entry function before invoking the kvm_set_irq function (CVE-2012-2137).

The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context (CVE-2014-1874).
