  - It was found that the Linux kernel's implementation of     vectored pipe read and write functionality did not take     into account the I/O vectors that were already     processed when retrying after a failed atomic access     operation, potentially resulting in memory corruption     due to an I/O vector array overrun. A local,     unprivileged user could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-1805)

  - net/llc/sysctl_net_llc.c in the Linux kernel before     3.19 uses an incorrect data type in a sysctl table,     which allows local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry.(CVE-2015-2041)

  - net/rds/sysctl.c in the Linux kernel before 3.19 uses     an incorrect data type in a sysctl table, which allows     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry.(CVE-2015-2042)

  - 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-2015-2150)

  - It was found that the Linux kernel's ping socket     implementation did not properly handle socket unhashing     during spurious disconnects, which could lead to a     use-after-free flaw. On x86-64 architecture systems, a     local user able to create ping sockets could use this     flaw to crash the system. On non-x86-64 architecture     systems, a local user able to create ping sockets could     use this flaw to escalate their privileges on the     system.(CVE-2015-3636)

  - An inode data validation error was found in Linux     kernels built with UDF file system (CONFIG_UDF_FS)     support. An attacker able to mount a     corrupted/malicious UDF file system image could cause     the kernel to crash.(CVE-2015-4167)

  - A flaw was discovered in the way the Linux kernel's TTY     subsystem handled the tty shutdown phase. A local,     unprivileged user could use this flaw to cause denial     of service on the system by holding a reference to the     ldisc lock during tty shutdown, causing a     deadlock.(CVE-2015-4170)

  - A flaw was discovered in the kernel's collect_mounts     function. If the kernel's audit subsystem called     collect_mounts to audit an unmounted path, it could     panic the system. With this flaw, an unprivileged user     could call umount(MNT_DETACH) to launch a     denial-of-service attack.(CVE-2015-4177)

  - A DoS flaw was found for a Linux kernel built for the     x86 architecture which had the KVM virtualization     support(CONFIG_KVM) enabled. The kernel would be     vulnerable to a NULL pointer dereference flaw in Linux     kernel's kvm_apic_has_events() function while doing an     ioctl. An unprivileged user able to access the     '/dev/kvm' device could use this flaw to crash the     system kernel.(CVE-2015-4692)

  - A flaw was found in the kernel's implementation of the     Berkeley Packet Filter (BPF). A local attacker could     craft BPF code to crash the system by creating a     situation in which the JIT compiler would fail to     correctly optimize the JIT image on the last pass. This     would lead to the CPU executing instructions that were     not part of the JIT code.(CVE-2015-4700)

  - A buffer overflow flaw was found in the way the Linux     kernel's virtio-net subsystem handled certain fraglists     when the GRO (Generic Receive Offload) functionality     was enabled in a bridged network configuration. An     attacker on the local network could potentially use     this flaw to crash the system, or, although unlikely,     elevate their privileges on the system.(CVE-2015-5156)

The linux-2.6 update issued as DLA-246-1 caused regressions. This update corrects the defective patches applied in that update causing these problems. For reference the original advisory text follows.

This update fixes the CVEs described below.

CVE-2011-5321

Jiri Slaby discovered that tty_driver_lookup_tty() may leak a reference to the tty driver. A local user could use this flaw to crash the system.

CVE-2012-6689

Pablo Neira Ayuso discovered that non-root user-space processes can send forged Netlink notifications to other processes. A local user could use this flaw for denial of service or privilege escalation.

CVE-2014-3184

Ben Hawkes discovered that various HID drivers may over-read the report descriptor buffer, possibly resulting in a crash if a HID with a crafted descriptor is plugged in.

CVE-2014-8159

It was found that the Linux kernel's InfiniBand/RDMA 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-2014-9683

Dmitry Chernenkov discovered that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding, resulting in local denial of service.

CVE-2014-9728 / CVE-2014-9729 / CVE-2014-9730 / CVE-2014-9731 / CVE-2015-4167

Carl Henrik Lunde discovered that the UDF implementation is missing several necessary length checks. A local user that can mount devices could use these various flaws to crash the system, to leak information from the kernel, or possibly for privilege escalation.

CVE-2015-1805

Red Hat discovered that the pipe iovec read and write implementations may iterate over the iovec twice but will modify the iovec such that the second iteration accesses the wrong memory. A local user could use this flaw to crash the system or possibly for privilege escalation.
This may also result in data corruption and information leaks in pipes between non-malicious processes.

CVE-2015-2041

Sasha Levin discovered that the LLC subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this possibly allows privilege escalation from a process with CAP_NET_ADMIN capability; it also results in a trivial information leak.

CVE-2015-2042

Sasha Levin discovered that the RDS subsystem exposed some variables as sysctls with the wrong type. On a 64-bit kernel, this results in a trivial information leak.

CVE-2015-2830

Andrew Lutomirski discovered that when a 64-bit task on an amd64 kernel makes a fork(2) or clone(2) system call using int $0x80, the 32-bit compatibility flag is set (correctly) but is not cleared on return. As a result, both seccomp and audit will misinterpret the following system call by the task(s), possibly leading to a violation of security policy.

CVE-2015-2922

Modio AB discovered that the IPv6 subsystem would process a router advertisement that specifies no route but only a hop limit, which would then be applied to the interface that received it. This can result in loss of IPv6 connectivity beyond the local network.

This may be mitigated by disabling processing of IPv6 router advertisements if they are not needed: sysctl net.ipv6.conf.default.accept_ra=0 sysctl net.ipv6.conf.<interface>.accept_ra=0

CVE-2015-3339

It was found that the execve(2) system call can race with inode attribute changes made by chown(2). Although chown(2) clears the setuid/setgid bits of a file if it changes the respective owner ID, this race condition could result in execve(2) setting effective uid/gid to the new owner ID, a privilege escalation.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze12.

For the oldstable distribution (wheezy), these problems were fixed in linux version 3.2.68-1+deb7u1 or earlier, except for CVE-2015-1805 and CVE-2015-4167 which will be fixed soon.

For the stable distribution (jessie), these problems were fixed in linux version 3.16.7-ckt11-1 or earlier, except for CVE-2015-4167 which will be fixed later.

We recommend that you upgrade your linux-2.6 packages.

The openSUSE 13.2 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2015-3290: A flaw was found in the way the Linux     kernels nested NMI handler and espfix64 functionalities     interacted during NMI processing. A local, unprivileged     user could use this flaw to crash the system or,     potentially, escalate their privileges on the system.

  - CVE-2015-3212: A race condition flaw was found in the     way the Linux kernels SCTP implementation handled     Address Configuration lists when performing Address     Configuration Change (ASCONF). A local attacker could     use this flaw to crash the system via a race condition     triggered by setting certain ASCONF options on a socket.

  - CVE-2015-5364: A remote denial of service (hang) via UDP     flood with incorrect package checksums was fixed.
    (bsc#936831).

  - CVE-2015-5366: A remote denial of service (unexpected     error returns) via UDP flood with incorrect package     checksums was fixed. (bsc#936831).

  - CVE-2015-4700: A local user could have created a bad     instruction in the JIT processed BPF code, leading to a     kernel crash (bnc#935705).

  - CVE-2015-1420: Race condition in the handle_to_path     function in fs/fhandle.c in the Linux kernel allowed     local users to bypass intended size restrictions and     trigger read operations on additional memory locations     by changing the handle_bytes value of a file handle     during the execution of this function (bnc#915517).

  - CVE-2015-4692: The kvm_apic_has_events function in     arch/x86/kvm/lapic.h in the Linux kernel allowed local     users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact by leveraging /dev/kvm access     for an ioctl call (bnc#935542).

  - CVE-2015-4167 CVE-2014-9728 CVE-2014-9730 CVE-2014-9729     CVE-2014-9731: Various problems in the UDF filesystem     were fixed that could lead to crashes when mounting     prepared udf filesystems.

  - CVE-2015-4002: drivers/staging/ozwpan/ozusbsvc1.c in the     OZWPAN driver in the Linux kernel did not ensure that     certain length values are sufficiently large, which     allowed remote attackers to cause a denial of service     (system crash or large loop) or possibly execute     arbitrary code via a crafted packet, related to the (1)     oz_usb_rx and (2) oz_usb_handle_ep_data functions     (bnc#933934).

  - CVE-2015-4003: The oz_usb_handle_ep_data function in     drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel allowed remote attackers to cause a     denial of service (divide-by-zero error and system     crash) via a crafted packet (bnc#933934).

  - CVE-2015-4001: Integer signedness error in the     oz_hcd_get_desc_cnf function in     drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in     the Linux kernel allowed remote attackers to cause a     denial of service (system crash) or possibly execute     arbitrary code via a crafted packet (bnc#933934).

  - CVE-2015-4036: A potential memory corruption in     vhost/scsi was fixed.

  - CVE-2015-2922: The ndisc_router_discovery function in     net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol     implementation in the IPv6 stack in the Linux kernel     allowed remote attackers to reconfigure a hop-limit     setting via a small hop_limit value in a Router     Advertisement (RA) message (bnc#922583).

  - CVE-2015-3636: It was found that the Linux kernels ping     socket implementation did not properly handle socket     unhashing during spurious disconnects, which could lead     to a use-after-free flaw. On x86-64 architecture     systems, a local user able to create ping sockets could     use this flaw to crash the system. On non-x86-64     architecture systems, a local user able to create ping     sockets could use this flaw to escalate their privileges     on the system.

  - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux     kernel used an incorrect data type in a sysctl table,     which allowed local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry (bnc#919007).

  - CVE-2015-3339: Race condition in the prepare_binprm     function in fs/exec.c in the Linux kernel allowed local     users to gain privileges by executing a setuid program     at a time instant when a chown to root is in progress,     and the ownership is changed but the setuid bit is not     yet stripped.

  - CVE-2015-1465: The IPv4 implementation in the Linux     kernel did not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allowed remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of packets     (bnc#916225).

The SUSE Linux Enterprise Server 11 SP2 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2015-5707: An integer overflow in the SCSI generic     driver could be potentially used by local attackers to     crash the kernel or execute code.

  - CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux     kernel did not prevent the TS_COMPAT flag from reaching     a user-mode task, which might have allowed local users     to bypass the seccomp or audit protection mechanism via     a crafted application that uses the (1) fork or (2)     close system call, as demonstrated by an attack against     seccomp before 3.16 (bnc#926240).

  - CVE-2015-0777: drivers/xen/usbback/usbback.c in the     Linux kernel allowed guest OS users to obtain sensitive     information from uninitialized locations in host OS     kernel memory via unspecified vectors (bnc#917830).

  - CVE-2015-2150: Xen and the Linux kernel did not properly     restrict access to PCI command registers, which might     have allowed local guest 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     (bnc#919463).

  - CVE-2015-5364: A remote denial of service (hang) via UDP     flood with incorrect package checksums was fixed.
    (bsc#936831).

  - CVE-2015-5366: A remote denial of service (unexpected     error returns) via UDP flood with incorrect package     checksums was fixed. (bsc#936831).

  - CVE-2015-1420: CVE-2015-1420: Race condition in the     handle_to_path function in fs/fhandle.c in the Linux     kernel allowed local users to bypass intended size     restrictions and trigger read operations on additional     memory locations by changing the handle_bytes value of a     file handle during the execution of this function     (bnc#915517).

  - CVE-2015-4700: A local user could have created a bad     instruction in the JIT processed BPF code, leading to a     kernel crash (bnc#935705).

  - CVE-2015-1805: The (1) pipe_read and (2) pipe_write     implementations in fs/pipe.c in the Linux kernel did not     properly consider the side effects of failed
    __copy_to_user_inatomic and __copy_from_user_inatomic     calls, which allowed local users to cause a denial of     service (system crash) or possibly gain privileges via a     crafted application, aka an 'I/O vector array overrun'     (bnc#933429).

  - CVE-2015-3331: The __driver_rfc4106_decrypt function in     arch/x86/crypto/aesni-intel_glue.c in the Linux kernel     did not properly determine the memory locations used for     encrypted data, which allowed context-dependent     attackers to cause a denial of service (buffer overflow     and system crash) or possibly execute arbitrary code by     triggering a crypto API call, as demonstrated by use of     a libkcapi test program with an AF_ALG(aead) socket     (bnc#927257).

  - CVE-2015-2922: The ndisc_router_discovery function in     net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol     implementation in the IPv6 stack in the Linux kernel     allowed remote attackers to reconfigure a hop-limit     setting via a small hop_limit value in a Router     Advertisement (RA) message (bnc#922583).

  - CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux     kernel used an incorrect data type in a sysctl table,     which allowed local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry (bnc#919007).

  - CVE-2015-3636: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel did not initialize a     certain list data structure during an unhash operation,     which allowed local users to gain privileges or cause a     denial of service (use-after-free and system crash) by     leveraging the ability to make a SOCK_DGRAM socket     system call for the IPPROTO_ICMP or IPPROTO_ICMPV6     protocol, and then making a connect system call after a     disconnect (bnc#929525).

  - CVE-2014-8086: Race condition in the     ext4_file_write_iter function in fs/ext4/file.c in the     Linux kernel allowed local users to cause a denial of     service (file unavailability) via a combination of a     write action and an F_SETFL fcntl operation for the     O_DIRECT flag (bnc#900881).

  - CVE-2014-8159: The InfiniBand (IB) implementation in the     Linux kernel did not properly restrict use of User Verbs     for registration of memory regions, which allowed local     users to access arbitrary physical memory locations, and     consequently cause a denial of service (system crash) or     gain privileges, by leveraging permissions on a uverbs     device under /dev/infiniband/ (bnc#914742).

  - CVE-2014-9683: Off-by-one error in the     ecryptfs_decode_from_filename function in     fs/ecryptfs/crypto.c in the eCryptfs subsystem in the     Linux kernel allowed local users to cause a denial of     service (buffer overflow and system crash) or possibly     gain privileges via a crafted filename (bnc#918333).

  - CVE-2015-2042: net/rds/sysctl.c in the Linux kernel used     an incorrect data type in a sysctl table, which allowed     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry (bnc#919018).

  - CVE-2015-1421: Use-after-free vulnerability in the     sctp_assoc_update function in net/sctp/associola.c in     the Linux kernel allowed remote attackers to cause a     denial of service (slab corruption and panic) or     possibly have unspecified other impact by triggering an     INIT collision that leads to improper handling of     shared-key data (bnc#915577).

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.

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 :

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel through 4.14.15 allows local users     to obtain sensitive address information by reading     dmesg data from an SBS HC printk call.(CVE-2018-5750i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. A use-after-free is possible in     try_merge_free_space() when mounting a crafted btrfs     image due to a lack of chunk type flag checks in     btrfs_check_chunk_valid() in the fs/btrfs/volumes.c     function. This could lead to a denial of service or     other unspecified impact.(CVE-2018-14611i1/4%0

  - A flaw was found in the way the Linux kernel visor     driver handles certain invalid USB device descriptors.
    The driver assumes that the device always has at least     one bulk OUT endpoint. By using a specially crafted USB     device (without a bulk OUT endpoint), an unprivileged     user with physical access could trigger a kernel     NULL-pointer dereference and cause a system panic     (denial of service).(CVE-2015-7566i1/4%0

  - It was found that the RFC 5961 challenge ACK rate     limiting as implemented in the Linux kernel's     networking subsystem allowed an off-path attacker to     leak certain information about a given connection by     creating congestion on the global challenge ACK rate     limit counter and then measuring the changes by probing     packets. An off-path attacker could use this flaw to     either terminate TCP connection and/or inject payload     into non-secured TCP connection between two endpoints     on the network.(CVE-2016-5696i1/4%0

  - It was found that the Bluebooth Network Encapsulation     Protocol (BNEP) implementation did not validate the     type of second socket passed to the BNEPCONNADD     ioctl(), which could lead to memory corruption. A local     user with the CAP_NET_ADMIN capability can use this for     denial of service (crash or data corruption) or     possibly for privilege escalation. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we feel it is unlikely.(CVE-2017-15868i1/4%0

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299i1/4%0

  - The rfcomm_sock_bind function in     net/bluetooth/rfcomm/sock.c in the Linux kernel before     4.2 allows local users to obtain sensitive information     or cause a denial of service (NULL pointer dereference)     via vectors involving a bind system call on a Bluetooth     RFCOMM socket.(CVE-2015-8956i1/4%0

  - arch/mips/include/asm/thread_info.h in the Linux kernel     before 3.14.8 on the MIPS platform does not configure
    _TIF_SECCOMP checks on the fast system-call path, which     allows local users to bypass intended PR_SET_SECCOMP     restrictions by executing a crafted application without     invoking a trace or audit subsystem.(CVE-2014-4157i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem     code. A stack-out-of-bounds write in     ext4_update_inline_data() is possible when mounting and     writing to a crafted ext4 image. An attacker could use     this to cause a system crash and a denial of     service.(CVE-2018-10880i1/4%0

  - The aac_send_raw_srb function in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     through 3.12.1 does not properly validate a certain     size value, which allows local users to cause a denial     of service (invalid pointer dereference) or possibly     have unspecified other impact via an     FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted     SRB command.(CVE-2013-6380i1/4%0

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to an uncaught     exception issue. It could occur if an L2 guest was to     throw an exception which is not handled by an L1     guest.(CVE-2016-9588i1/4%0

  - A flaw was found in the alarm_timer_nsleep() function     in kernel/time/alarmtimer.c in the Linux kernel. The     ktime_add_safe() function is not used and an integer     overflow can happen causing an alarm not to fire if     using a large relative timeout.(CVE-2018-13053i1/4%0

  - net/llc/sysctl_net_llc.c in the Linux kernel before     3.19 uses an incorrect data type in a sysctl table,     which allows local users to obtain potentially     sensitive information from kernel memory or possibly     have unspecified other impact by accessing a sysctl     entry.(CVE-2015-2041i1/4%0

  - Incorrect error handling in the set_mempolicy() and     mbind() compat syscalls in 'mm/mempolicy.c' in the     Linux kernel allows local users to obtain sensitive     information from uninitialized stack data by triggering     failure of a certain bitmap operation.(CVE-2017-7616i1/4%0

  - The snd_msnd_interrupt function in     sound/isa/msnd/msnd_pinnacle.c in the Linux kernel     through 4.11.7 allows local users to cause a denial of     service (over-boundary access) or possibly have     unspecified other impact by changing the value of a     message queue head pointer between two kernel reads of     that value, aka a 'double fetch'     vulnerability.(CVE-2017-9984i1/4%0

  - An integer overflow was discovered in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     through 4.12.10. This flaw allows local users to cause     a denial of service (memory corruption and system     crash) by leveraging root access.(CVE-2017-14051i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4654i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's Virtual Dynamic Shared Object (vDSO)     implementation performed address randomization. A     local, unprivileged user could use this flaw to leak     kernel memory addresses to user-space.(CVE-2014-9585i1/4%0

  - The usbhid_parse function in     drivers/hid/usbhid/hid-core.c in the Linux kernel,     before 4.13.8, allows 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.(CVE-2017-16533i1/4%0

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106i1/4%0
