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.

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 Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with     CAP_SYS_ADMIN capability) can directly perform the     ioctl operations for dm device creation and removal and     this would typically be outside the direct control of     the unprivileged attacker.(CVE-2017-18203i1/4%0

  - The batadv_frag_merge_packets function in     net/batman-adv/fragmentation.c in the B.A.T.M.A.N.
    implementation in the Linux kernel through 3.18.1 uses     an incorrect length field during a calculation of an     amount of memory, which allows remote attackers to     cause a denial of service (mesh-node system crash) via     fragmented packets.(CVE-2014-9428i1/4%0

  - The regulator_ena_gpio_free function in     drivers/regulator/core.c in the Linux kernel allows     local users to gain privileges or cause a denial of     service (use-after-free) via a crafted     application.(CVE-2014-9940i1/4%0

  - The Linux kernel before 3.12, when UDP Fragmentation     Offload (UFO) is enabled, does not properly initialize     certain data structures, which allows local users to     cause a denial of service (memory corruption and system     crash) or possibly gain privileges via a crafted     application that uses the UDP_CORK option in a     setsockopt system call and sends both short and long     packets, related to the ip_ufo_append_data function in     net/ipv4/ip_output.c and the ip6_ufo_append_data     function in net/ipv6/ip6_output.c.(CVE-2013-4470i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Datagram Congestion Control Protocol (DCCP)     implementation freed SKB (socket buffer) resources for     a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO     option is set on the socket. A local, unprivileged user     could use this flaw to alter the kernel memory,     allowing them to escalate their privileges on the     system.(CVE-2017-6074i1/4%0

  - A NULL-pointer dereference vulnerability was found in     the Linux kernel's TCP stack, in     net/netfilter/nf_nat_redirect.c in the     nf_nat_redirect_ipv4() function. A remote,     unauthenticated user could exploit this flaw to create     a system crash (denial of service).(CVE-2015-8787i1/4%0

  - A use-after-free flaw was found in the CXGB3 kernel     driver when the network was considered to be congested.
    The kernel incorrectly misinterpreted the congestion as     an error condition and incorrectly freed or cleaned up     the socket buffer (skb). When the device then sent the     skb's queued data, these structures were referenced. A     local attacker could use this flaw to panic the system     (denial of service) or, with a local account, escalate     their privileges.(CVE-2015-8812i1/4%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-2015-5364i1/4%0

  - The timer_create syscall implementation in     kernel/time/posix-timers.c in the Linux kernel doesn't     properly validate the sigevent-i1/4zsigev_notify field,     which leads to out-of-bounds access in the show_timer     function.(CVE-2017-18344i1/4%0

  - A flaw was discovered in the way the Linux kernel dealt     with paging structures. When the kernel invalidated a     paging structure that was not in use locally, it could,     in principle, race against another CPU that is     switching to a process that uses the paging structure     in question. A local user could use a thread running     with a stale cached virtual-i1/4zphysical translation to     potentially escalate their privileges if the     translation in question were writable and the physical     page got reused for something critical (for example, a     page table).(CVE-2016-2069i1/4%0

  - Use after free vulnerability was found in percpu using     previously allocated memory in bpf. First
    __alloc_percpu_gfp() is called, then the memory is     freed with free_percpu() which triggers async     pcpu_balance_work and then pcpu_extend_area_map could     use a chunk after it has been freed.(CVE-2016-4794i1/4%0

  - A missing authorization check in the     fscrypt_process_policy function in fs/crypto/policy.c     in the ext4 and f2fs filesystem encryption support in     the Linux kernel allows a user to assign an encryption     policy to a directory owned by a different user,     potentially creating a denial of     service.(CVE-2016-10318i1/4%0

  - 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-2014-1874i1/4%0

  - The vfe31_proc_general function in     drivers/media/video/msm/vfe/msm_vfe31.c in the     MSM-VFE31 driver for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, does not validate a     certain id value, which allows attackers to gain     privileges or cause a denial of service (memory     corruption) via an application that makes a crafted     ioctl call.(CVE-2014-9410i1/4%0

  - A vulnerability was found in the Key Management sub     component of the Linux kernel, where when trying to     issue a KEYTCL_READ on a negative key would lead to a     NULL pointer dereference. A local attacker could use     this flaw to crash the kernel.(CVE-2017-12192i1/4%0

  - Out-of-bounds memory read in the x509_decode_time     function in x509_cert_parser.c in Linux kernels 4.3-rc1     and after.(CVE-2015-5327i1/4%0

  - It was found that the espfix functionality does not     work for 32-bit KVM paravirtualized guests. A local,     unprivileged guest user could potentially use this flaw     to leak kernel stack addresses.(CVE-2014-8134i1/4%0

  - An out-of-bounds write flaw was found in the way the     Apple Magic Mouse/Trackpad multi-touch driver handled     Human Interface Device (HID) reports with an invalid     size. An attacker with physical access to the system     could use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-3181i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's key management subsystem handled keyring     object reference counting in certain error path of the     join_session_keyring() function. A local, unprivileged     user could use this flaw to escalate their privileges     on the system.(CVE-2016-0728i1/4%0

  - Use-after-free vulnerability in the skb_segment     function in net/core/skbuff.c in the Linux kernel     through 3.13.6 allows attackers to obtain sensitive     information from kernel memory by leveraging the     absence of a certain orphaning     operation.(CVE-2014-0131i1/4%0

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0439 advisory.

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

    * A denial of service flaw was found in the way the Linux kernel's IPv6     implementation processed IPv6 router advertisement (RA) packets.
    An attacker able to send a large number of RA packets to a target system     could potentially use this flaw to crash the target system. (CVE-2014-2309,     Important)

    * A flaw was found in the way the Linux kernel's netfilter connection     tracking implementation for Datagram Congestion Control Protocol (DCCP)     packets used the skb_header_pointer() function. A remote attacker could use     this flaw to send a specially crafted DCCP packet to crash the system or,     potentially, escalate their privileges on the system. (CVE-2014-2523,     Important)

    * A flaw was found in the way the Linux kernel's CIFS implementation     handled uncached write operations with specially crafted iovec structures.
    An unprivileged local user with access to a CIFS share could use this flaw     to crash the system, leak kernel memory, or, potentially, escalate their     privileges on the system. (CVE-2014-0069, Moderate)

    * A flaw was found in the way the Linux kernel handled pending Floating     Pointer Unit (FPU) exceptions during the switching of tasks. A local     attacker could use this flaw to terminate arbitrary processes on the     system, causing a denial of service, or, potentially, escalate their     privileges on the system. Note that this flaw only affected systems using     AMD CPUs on both 32-bit and 64-bit architectures. (CVE-2014-1438, Moderate)

    * It was found that certain protocol handlers in the Linux kernel's     networking implementation could set the addr_len value without initializing     the associated data structure. A local, unprivileged user could use this     flaw to leak kernel stack memory to user space using the recvmsg, recvfrom,     and recvmmsg system calls. (CVE-2013-7263, CVE-2013-7265, Low)

    * An information leak flaw was found in the Linux kernel's netfilter     connection tracking IRC NAT helper implementation that could allow a remote     attacker to disclose portions of kernel stack memory during IRC DCC (Direct     Client-to-Client) communication over NAT. (CVE-2014-1690, Low)

    * A denial of service flaw was discovered in the way the Linux kernel's     SELinux implementation handled files with an empty SELinux security     context. A local user who has the CAP_MAC_ADMIN capability could use this     flaw to crash the system. (CVE-2014-1874, Low)

    Red Hat would like to thank Al Viro for reporting CVE-2014-0069.
    The CVE-2014-1690 issue was discovered by Daniel Borkmann of Red Hat.

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2014-3043 advisory.

  - The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly     handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger     kfree operations and gain privileges by leveraging write access to a /dev/fd device. (CVE-2014-1737)

  - The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not     properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows     local users to obtain sensitive information from kernel heap memory by leveraging write access to a     /dev/fd device. (CVE-2014-1738)

  - The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through     3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-     length write operation. (CVE-2013-6378)

  - 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)

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

* A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important)

* A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important)

* It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low)

Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.

* It was discovered that the proc_ns_follow_link() function did not properly return the LAST_BIND value in the last pathname component as is expected for procfs symbolic links, which could lead to excessive freeing of memory and consequent slab corruption. A local, unprivileged user could use this flaw to crash the system.
(CVE-2014-0203, Moderate)

* A flaw was found in the way the Linux kernel handled exceptions when user-space applications attempted to use the linkage stack. On IBM S/390 systems, a local, unprivileged user could use this flaw to crash the system. (CVE-2014-2039, Moderate)

* An invalid pointer dereference flaw was found in the Marvell 8xxx Libertas WLAN (libertas) driver in the Linux kernel. A local user able to write to a file that is provided by the libertas driver and located on the debug file system (debugfs) could use this flaw to crash the system. Note: The debugfs file system must be mounted locally to exploit this issue. It is not mounted by default. (CVE-2013-6378, Low)

Multiple vulnerabilities has been found and corrected in the Linux kernel :

kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number (CVE-2014-3917).

The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification (CVE-2014-3153).

Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions (CVE-2014-2672).

The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the
__skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced (CVE-2014-3144).

The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced (CVE-2014-3145).

Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that leverages an improperly managed reference counter (CVE-2014-2851).

The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the LECHO !OPOST case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings (CVE-2014-0196).

The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device (CVE-2014-1738).

The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device (CVE-2014-1737).

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 (CVE-2014-2678).

drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions (CVE-2014-0077).

The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets (CVE-2014-2309).

Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2897).

net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function (CVE-2014-2523).

Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c (CVE-2014-2706).

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).

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

The pn_recvmsg function in net/phonet/datagram.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.

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.

The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call, related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.

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.

The 3.13.3 stable update contains a number of important fixes across the tree. The 3.13.2 rebase contains support for additional hardware, some new features and a number of important bug fixes across the tree.
