The ieee80211_fragment function in net/mac80211/tx.c in the Linux kernel before 3.13.5 does not properly maintain a certain tail pointer, which allows remote attackers to obtain sensitive cleartext information by reading packets.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c     (CVE-2017-18017)

  - The ia64 subsystem in the Linux kernel before 2.6.26 allows local users to cause a denial of service     (stack consumption and system crash) via a crafted application that leverages the mishandling of invalid     Register Stack Engine (RSE) state. (CVE-2006-3635)

  - drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize     videobuf_mapping data structures, which allows local users to trigger an incorrect count value and     videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321. (CVE-2007-6761)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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 :

  - drivers/gpu/msm/kgsl.c in the MSM graphics driver (aka     GPU driver) for the Linux kernel 3.x, as used in     Qualcomm Innovation Center (QuIC) Android contributions     for MSM devices and other products, mishandles the     KGSL_MEMFLAGS_GPUREADONLY flag, which allows attackers     to gain privileges by leveraging accidental read-write     mappings, aka Qualcomm internal bug     CR988993.(CVE-2016-2067i1/4%0

  - Integer overflow in the mem_check_range function in     drivers/infiniband/sw/rxe/rxe_mr.c in the Linux kernel     before 4.9.10 allows local users to cause a denial of     service (memory corruption), obtain sensitive     information from kernel memory, or possibly have     unspecified other impact via a write or read request     involving the 'RDMA protocol over infiniband' (aka Soft     RoCE) technology.(CVE-2016-8636i1/4%0

  - Heap-based buffer overflow in the     logi_dj_ll_raw_request function in     drivers/hid/hid-logitech-dj.c in the Linux kernel     before 3.16.2 allows physically proximate attackers to     cause a denial of service (system crash) or possibly     execute arbitrary code via a crafted device that     specifies a large report size for an LED     report.(CVE-2014-3183i1/4%0

  - The futex_requeue function in kernel/futex.c in the     Linux kernel, before 4.14.15, might allow attackers to     cause a denial of service (integer overflow) or     possibly have unspecified other impacts by triggering a     negative wake or requeue value. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2018-6927i1/4%0

  - The hub_activate function in drivers/usb/core/hub.c in     the Linux kernel before 4.3.5 does not properly     maintain a hub-interface data structure, which allows     physically proximate attackers to cause a denial of     service (invalid memory access and system crash) or     possibly have unspecified other impact by unplugging a     USB hub device.(CVE-2015-8816i1/4%0

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.(CVE-2016-9576i1/4%0

  - A security flaw was found in the Linux kernel's     networking subsystem that destroying the network     interface with huge number of ipv4 addresses assigned     keeps 'rtnl_lock' spinlock for a very long time (up to     hour). This blocks many network-related operations,     including creation of new incoming ssh connections.The     problem is especially important for containers, as the     container owner has enough permissions to trigger this     and block a network access on a whole host, outside the     container.(CVE-2016-3156i1/4%0

  - The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allows     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an     io_ti USB serial device) to trigger an integer     underflow.(CVE-2017-8924i1/4%0

  - The IPv4 implementation in the Linux kernel before     3.18.8 does not properly consider the length of the     Read-Copy Update (RCU) grace period for redirecting     lookups in the absence of caching, which allows remote     attackers to cause a denial of service (memory     consumption or system crash) via a flood of     packets.(CVE-2015-1465i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9728i1/4%0

  - net/ipv6/ip6_output.c in the Linux kernel through     3.11.4 does not properly determine the need for UDP     Fragmentation Offload (UFO) processing of small packets     after the UFO queueing of a large packet, which allows     remote attackers to cause a denial of service (memory     corruption and system crash) or possibly have     unspecified other impact via network traffic that     triggers a large response packet.(CVE-2013-4387i1/4%0

  - It was found that nfsd is missing permissions check     when setting ACL on files, this may allow a local users     to gain access to any file by setting a crafted     ACL.(CVE-2016-1237i1/4%0

  - In the Linux kernel before 4.13.5, a local user could     create keyrings for other users via keyctl commands,     setting unwanted defaults or causing a denial of     service.(CVE-2017-18270i1/4%0

  - An issue was discovered in the Linux kernel where an     integer overflow in kernel/time/posix-timers.c in the     POSIX timer code is caused by the way the overrun     accounting works. Depending on interval and expiry time     values, the overrun can be larger than INT_MAX, but the     accounting is int based. This basically makes the     accounting values, which are visible to user space via     timer_getoverrun(2) and siginfo::si_overrun,     random.(CVE-2018-12896i1/4%0

  - 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-2018-18281i1/4%0

  - The netfilter subsystem in the Linux kernel through     4.15.7 mishandles the case of a rule blob that contains     a jump but lacks a user-defined chain, which allows     local users to cause a denial of service (NULL pointer     dereference) by leveraging the CAP_NET_RAW or     CAP_NET_ADMIN capability, related to arpt_do_table in     net/ipv4/netfilter/arp_tables.c, ipt_do_table in     net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in     net/ipv6/netfilter/ip6_tables.c.(CVE-2018-1065i1/4%0

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084i1/4%0

  - The acm_probe function in drivers/usb/class/cdc-acm.c     in the Linux kernel before 4.5.1 allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and system crash) via a USB device     without both a control and a data endpoint     descriptor.(CVE-2016-3138i1/4%0

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604i1/4%0

  - An information leak flaw was found in the Linux     kernel's IEEE 802.11 wireless networking     implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8     bytes of plaintext.(CVE-2014-8709i1/4%0

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS 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 installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way the Linux kernel's SCTP     implementation validated INIT chunks when performing     Address Configuration Change (ASCONF). A remote     attacker could use this flaw to crash the system by     sending a specially crafted SCTP packet to trigger a     NULL pointer dereference on the system.(CVE-2014-7841)

  - It was found that reporting emulation failures to user     space could lead to either a local (CVE-2014-7842) or a     L2-i1/4zL1 (CVE-2010-5313) denial of service. In the case     of a local denial of service, an attacker must have     access to the MMIO area or be able to access an I/O     port. Please note that on certain systems, HPET is     mapped to userspace as part of vdso (vvar) and thus an     unprivileged user may generate MMIO transactions (and     enter the emulator) this way.(CVE-2014-7842)

  - The pivot_root implementation in fs/namespace.c in the     Linux kernel through 3.17 does not properly interact     with certain locations of a chroot directory, which     allows local users to cause a denial of service     (mount-tree loop) via . (dot) values in both arguments     to the pivot_root system call.(CVE-2014-7970)

  - The do_umount function in fs/namespace.c in the Linux     kernel through 3.17 does not require the CAP_SYS_ADMIN     capability for do_remount_sb calls that change the root     filesystem to read-only, which allows local users to     cause a denial of service (loss of writability) by     making certain unshare system calls, clearing the /     MNT_LOCKED flag, and making an MNT_FORCE umount system     call.(CVE-2014-7975)

  - 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-2014-8086)

  - A flaw was found in the way the Linux kernel's     netfilter subsystem handled generic protocol tracking.
    As demonstrated in the Stream Control Transmission     Protocol (SCTP) case, a remote attacker could use this     flaw to bypass intended iptables rule restrictions when     the associated connection tracking module was not     loaded on the system.(CVE-2014-8160)

  - It was found that due to excessive files_lock locking,     a soft lockup could be triggered in the Linux kernel     when performing asynchronous I/O operations. A local,     unprivileged user could use this flaw to crash the     system.(CVE-2014-8172)

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's madvise MADV_WILLNEED functionality     handled page table locking. A local, unprivileged user     could use this flaw to crash the system.(CVE-2014-8173)

  - It was found that the fix for CVE-2014-3601 was     incomplete: the Linux kernel's kvm_iommu_map_pages()     function still handled IOMMU mapping failures     incorrectly. A privileged user in a guest with an     assigned host device could use this flaw to crash the     host.(CVE-2014-8369)

  - The instruction decoder in arch/x86/kvm/emulate.c in     the KVM subsystem in the Linux kernel before 3.18-rc2     lacks intended decoder-table flags for certain     RIP-relative instructions, which allows guest OS users     to cause a denial of service (NULL pointer dereference     and host OS crash) via a crafted     application.(CVE-2014-8480)

  - The instruction decoder in arch/x86/kvm/emulate.c in     the KVM subsystem in the Linux kernel before 3.18-rc2     does not properly handle invalid instructions, which     allows guest OS users to cause a denial of service     (NULL pointer dereference and host OS crash) via a     crafted application that triggers (1) an improperly     fetched instruction or (2) an instruction that occupies     too many bytes. NOTE: this vulnerability exists because     of an incomplete fix for CVE-2014-8480.(CVE-2014-8481)

  - A flaw was found in the way the Linux kernel's VFS     subsystem handled file system locks. A local,     unprivileged user could use this flaw to trigger a     deadlock in the kernel, causing a denial of service on     the system.(CVE-2014-8559)

  - An information leak flaw was found in the Linux     kernel's IEEE 802.11 wireless networking     implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8     bytes of plaintext.(CVE-2014-8709)

  - A stack-based buffer overflow flaw was found in the     TechnoTrend/Hauppauge DEC USB device driver. A local     user with write access to the corresponding device     could use this flaw to crash the kernel or,     potentially, elevate their privileges on the     system.(CVE-2014-8884)

  - The do_double_fault function in arch/x86/kernel/traps.c     in the Linux kernel through 3.17.4 does not properly     handle faults associated with the Stack Segment (SS)     segment register, which allows local users to cause a     denial of service (panic) via a modify_ldt system call,     as demonstrated by sigreturn_32 in the     linux-clock-tests test suite.(CVE-2014-9090)

  - A flaw was found in the way the Linux kernel handled GS     segment register base switching when recovering from a     #SS (stack segment) fault on an erroneous return to     user space. A local, unprivileged user could use this     flaw to escalate their privileges on the     system.(CVE-2014-9322)

  - An information leak flaw was found in the way the Linux     kernel changed certain segment registers and     thread-local storage (TLS) during a context switch. A     local, unprivileged user could use this flaw to leak     the user space TLS base address of an arbitrary     process.(CVE-2014-9419)

  - It was found that the Linux kernel's ISO file system     implementation did not correctly limit the traversal of     Rock Ridge extension Continuation Entries (CE). An     attacker with physical access to the system could use     this flaw to trigger an infinite loop in the kernel,     resulting in a denial of service.(CVE-2014-9420)

  - A race condition flaw was found in the way the Linux     kernel keys management subsystem performed key garbage     collection. A local attacker could attempt accessing a     key while it was being garbage collected, which would     cause the system to crash.(CVE-2014-9529)

  - An information leak flaw was found in the way the Linux     kernel's ISO9660 file system implementation accessed     data on an ISO9660 image with RockRidge Extension     Reference (ER) records. An attacker with physical     access to the system could use this flaw to disclose up     to 255 bytes of kernel memory.(CVE-2014-9584)

  - 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-2014-9585)

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

* A flaw was found in the way Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. (CVE-2014-3940, Moderate)

* A buffer overflow flaw was found in the way the Linux kernel's eCryptfs implementation decoded encrypted file names. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-9683, Moderate)

* A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. (CVE-2015-3339, Moderate)

* Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer. (CVE-2014-3184, Low)

* An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low)

* It was found that the espfix functionality could be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks), and using that segment on the stack. A local, unprivileged user could potentially use this flaw to leak kernel stack addresses. (CVE-2014-8133, Low)

* An information leak flaw was found in the Linux kernel's IEEE 802.11 wireless networking implementation. When software encryption was used, a remote attacker could use this flaw to leak up to 8 bytes of plaintext. (CVE-2014-8709, Low)

* It was found that the Linux kernel KVM subsystem's sysenter instruction emulation was not sufficient. An unprivileged guest user could use this flaw to escalate their privileges by tricking the hypervisor to emulate a SYSENTER instruction in 16-bit mode, if the guest OS did not initialize the SYSENTER model-specific registers (MSRs). Note: Certified guest operating systems for Scientific Linux with KVM do initialize the SYSENTER MSRs and are thus not vulnerable to this issue when running on a KVM hypervisor. (CVE-2015-0239, Low)

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

The SUSE Linux Enterprise 11 Service Pack 1 LTSS kernel was updated to fix security issues on kernels on the x86_64 architecture.

The following security bugs have been fixed :

  - CVE-2013-4299: Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allowed remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block device (bnc#846404).

  - CVE-2014-8160: SCTP firewalling failed until the SCTP     module was loaded (bnc#913059).

  - CVE-2014-9584: The parse_rock_ridge_inode_internal     function in fs/isofs/rock.c in the Linux kernel before     3.18.2 did not validate a length value in the Extensions     Reference (ER) System Use Field, which allowed local     users to obtain sensitive information from kernel memory     via a crafted iso9660 image (bnc#912654).

  - CVE-2014-9585: The vdso_addr function in     arch/x86/vdso/vma.c in the Linux kernel through 3.18.2     did not properly choose memory locations for the vDSO     area, which made it easier for local users to bypass the     ASLR protection mechanism by guessing a location at the     end of a PMD (bnc#912705).

  - CVE-2014-9420: The rock_continue function in     fs/isofs/rock.c in the Linux kernel through 3.18.1 did     not restrict the number of Rock Ridge continuation     entries, which allowed local users to cause a denial of     service (infinite loop, and system crash or hang) via a     crafted iso9660 image (bnc#911325).

  - CVE-2014-0181: The Netlink implementation in the Linux     kernel through 3.14.1 did not provide a mechanism for     authorizing socket operations based on the opener of a     socket, which allowed local users to bypass intended     access restrictions and modify network configurations by     using a Netlink socket for the (1) stdout or (2) stderr     of a setuid program (bnc#875051).

  - CVE-2010-5313: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 2.6.38 allowed L2 guest OS users     to cause a denial of service (L1 guest OS crash) via a     crafted instruction that triggers an L2 emulation     failure report, a similar issue to CVE-2014-7842     (bnc#907822).

  - CVE-2014-7842: Race condition in arch/x86/kvm/x86.c in     the Linux kernel before 3.17.4 allowed guest OS users to     cause a denial of service (guest OS crash) via a crafted     application that performs an MMIO transaction or a PIO     transaction to trigger a guest userspace emulation error     report, a similar issue to CVE-2010-5313 (bnc#905312).

  - CVE-2014-3688: The SCTP implementation in the Linux     kernel before 3.17.4 allowed remote attackers to cause a     denial of service (memory consumption) by triggering a     large number of chunks in an associations output queue,     as demonstrated by ASCONF probes, related to     net/sctp/inqueue.c and net/sctp/sm_statefuns.c     (bnc#902351).

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:0290 advisory.

    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 XFS file system handled     replacing of remote attributes under certain conditions. A local user with     access to XFS file system mount could potentially use this flaw to escalate     their privileges on the system. (CVE-2015-0274, Important)

    * It was found that the Linux kernel's KVM implementation did not ensure     that the host CR4 control register value remained unchanged across VM     entries on the same virtual CPU. A local, unprivileged user could use this     flaw to cause denial of service on the system. (CVE-2014-3690, Moderate)

    * A flaw was found in the way Linux kernel's Transparent Huge Pages (THP)     implementation handled non-huge page migration. A local, unprivileged user     could use this flaw to crash the kernel by migrating transparent hugepages.
    (CVE-2014-3940, Moderate)

    * An out-of-bounds memory access flaw was found in the syscall tracing     functionality of the Linux kernel's perf subsystem. A local, unprivileged     user could use this flaw to crash the system. (CVE-2014-7825, Moderate)

    * An out-of-bounds memory access flaw was found in the syscall tracing     functionality of the Linux kernel's ftrace subsystem. On a system with     ftrace syscall tracing enabled, a local, unprivileged user could use this     flaw to crash the system, or escalate their privileges. (CVE-2014-7826,     Moderate)

    * 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-2014-8086, Moderate)

    * A flaw was found in the way the Linux kernel's netfilter subsystem     handled generic protocol tracking. As demonstrated in the Stream Control     Transmission Protocol (SCTP) case, a remote attacker could use this flaw to     bypass intended iptables rule restrictions when the associated connection     tracking module was not loaded on the system. (CVE-2014-8160, Moderate)

    * It was found that due to excessive files_lock locking, a soft lockup     could be triggered in the Linux kernel when performing asynchronous I/O     operations. A local, unprivileged user could use this flaw to crash the     system. (CVE-2014-8172, Moderate)

    * A NULL pointer dereference flaw was found in the way the Linux kernel's     madvise MADV_WILLNEED functionality handled page table locking. A local,     unprivileged user could use this flaw to crash the system. (CVE-2014-8173,     Moderate)

    * An information leak flaw was found in the Linux kernel's IEEE 802.11     wireless networking implementation. When software encryption was used, a     remote attacker could use this flaw to leak up to 8 bytes of plaintext.
    (CVE-2014-8709, Low)

    * A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge     DEC USB device driver. A local user with write access to the corresponding     device could use this flaw to crash the kernel or, potentially, elevate     their privileges on the system. (CVE-2014-8884, Low)
