kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor states "there is no kernel bug here.

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 snd_msndmidi_input_read function in     sound/isa/msnd/msnd_midi.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-2017-9985i1/4%0

  - An assertion failure issue was found in the Linux     kernel's KVM hypervisor module built to support     visualization on ARM64 architecture platforms. The     failure could occur while accessing Performance     Monitors Cycle Count Register (PMCCNTR) from a guest. A     privileged guest user could use this flaw to crash the     host kernel resulting in denial of     service.(CVE-2017-12168i1/4%0

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489i1/4%0

  - The hdpvr_probe function in     drivers/media/usb/hdpvr/hdpvr-core.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (improper error handling and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16644i1/4%0

  - The dvb frontend management subsystem in the Linux     kernel contains a use-after-free which can allow a     malicious user to write to memory that may be assigned     to another kernel structure. This could create memory     corruption, panic, or possibly other side     affects.(CVE-2017-16648i1/4%0

  - It was found that the Linux kernel's IPv6     implementation mishandled socket options. A local     attacker could abuse concurrent access to the socket     options to escalate their privileges, or cause a denial     of service (use-after-free and system crash) via a     crafted sendmsg system call.(CVE-2016-3841i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service     or unspecified other impact may occur by renaming a     file in a crafted ext4 filesystem     image.(CVE-2018-10879i1/4%0

  - A race condition was found in the Linux kernel, present     since v3.14-rc1 through v4.12. The race happens between     threads of inotify_handle_event() and vfs_rename()     while running the rename operation against the same     file. As a result of the race the next slab data or the     slab's free list pointer can be corrupted with     attacker-controlled data, which may lead to the     privilege escalation.(CVE-2017-7533i1/4%0

  - A privilege-escalation vulnerability was discovered in     the Linux kernel built with User Namespace     (CONFIG_USER_NS) support. The flaw occurred when the     ptrace() system call was used on a root-owned process     to enter a user namespace. A privileged namespace user     could exploit this flaw to potentially escalate their     privileges on the system, outside the original     namespace.(CVE-2015-8709i1/4%0

  - Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     before 4.5.2 allows local users to cause a denial of     service (memory corruption and system crash, or     spinlock) or possibly have unspecified other impact by     removing a network namespace, related to the     ppp_register_net_channel and ppp_unregister_channel     functions.(CVE-2016-4805i1/4%0

  - A flaw was found in the way the Linux kernel's     kvm_iommu_map_pages() function handled IOMMU mapping     failures. A privileged user in a guest with an assigned     host device could use this flaw to crash the     host.(CVE-2014-3601i1/4%0

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193i1/4%0

  - Multiple race conditions in drivers/char/adsprpc.c and     drivers/char/adsprpc_compat.c in the ADSPRPC driver for     the Linux kernel 3.x, as used in Qualcomm Innovation     Center (QuIC) Android contributions for MSM devices and     other products, allow attackers to cause a denial of     service (zero-value write) or possibly have unspecified     other impact via a COMPAT_FASTRPC_IOCTL_INVOKE_FD ioctl     call.(CVE-2015-0572i1/4%0

  - The sanity_check_ckpt function in fs/f2fs/super.c in     the Linux kernel before version 4.12.4 does not     validate the blkoff and segno arrays. This allows an     unprivileged, local user to cause a system panic and     DoS. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2017-10663i1/4%0

  - A stack overflow flaw caused by infinite recursion was     found in the way the Linux kernel's Universal Disk     Format (UDF) file system implementation processed     indirect Information Control Blocks (ICBs). An attacker     with physical access to the system could use a     specially crafted UDF image to crash the     system.(CVE-2014-6410i1/4%0

  - Race condition in the ion_ioctl function in     drivers/staging/android/ion/ion.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) by calling     ION_IOC_FREE on two CPUs at the same     time.(CVE-2016-9120i1/4%0

  - drivers/hid/hid-picolcd_core.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_PICOLCD is enabled, allows     physically proximate attackers to cause a denial of     service (NULL pointer dereference and OOPS) via a     crafted device.(CVE-2013-2899i1/4%0

  - A flaw was found in the Linux kernel's implementation     of overlayfs. An attacker can leak file resources in     the system by opening a large file with write     permissions on a overlay filesystem that is     insufficient to deal with the size of the write.When     unmounting the underlying device, the system is unable     to free an inode and this will consume resources.
    Repeating this for all available inodes and memory will     create a denial of service situation.(CVE-2015-8953i1/4%0

  - Buffer overflow in the mp_override_legacy_irq()     function in arch/x86/kernel/acpi/boot.c in the Linux     kernel through 4.12.2 allows local users to gain     privileges via a crafted ACPI table.(CVE-2017-11473i1/4%0

  - Use-after-free vulnerability in the     kvm_ioctl_create_device function in virt/kvm/kvm_main.c     in the Linux kernel before 4.8.13 allows host OS users     to cause a denial of service (host OS crash) or     possibly gain privileges via crafted ioctl calls on the     /dev/kvm device.(CVE-2016-10150i1/4%0

  - CVE-2015-8785: The fuse_fill_write_pages function in     fs/fuse/file.c in the Linux kernel allowed local users     to cause a denial of service (infinite loop) via a     writev system call that triggers a zero length for the     first segment of an iov. (bsc#963765)

  - CVE-2015-8551: The PCI backend driver in Xen, when     running on an x86 system and using Linux as the driver     domain, allowed local guest administrators to hit BUG     conditions and cause a denial of service (NULL pointer     dereference and host OS crash) by leveraging a system     with access to a passed-through MSI or MSI-X capable     physical PCI device and a crafted sequence of     XEN_PCI_OP_* operations, aka 'Linux pciback missing     sanity checks (bnc#957990).

  - CVE-2015-8552: The PCI backend driver in Xen, when     running on an x86 system and using Linux as the driver     domain, allowed local guest administrators to generate a     continuous stream of WARN messages and cause a denial of     service (disk consumption) by leveraging a system with     access to a passed-through MSI or MSI-X capable physical     PCI device and XEN_PCI_OP_enable_msi operations, aka     'Linux pciback missing sanity checks (bnc#957990).

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.57 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2015-8812: A flaw was found in the CXGB3 kernel     driver when the network was considered congested. The     kernel would incorrectly misinterpret the congestion as     an error condition and incorrectly free/clean up the     skb. When the device would then send the skb's queued,     these structures would be referenced and may panic the     system or allow an attacker to escalate privileges in a     use-after-free scenario. (bsc#966437)

  - CVE-2015-8816: A malicious USB device could cause a     kernel crash in the USB hub driver. (bnc#968010).

Features added :

  - A improved XEN blkfront module was added, which allows     more I/O bandwidth. (FATE#320625) It is called     xen-blkfront in PV, and xen-vbd-upstream in HVM mode.

The following security bugs were fixed :

  - CVE-2013-7446: Use-after-free vulnerability in     net/unix/af_unix.c in the Linux kernel allowed local     users to bypass intended AF_UNIX socket permissions or     cause a denial of service (panic) via crafted epoll_ctl     calls (bnc#955654).

  - CVE-2015-5707: Integer overflow in the sg_start_req     function in drivers/scsi/sg.c in the Linux kernel     allowed local users to cause a denial of service or     possibly have unspecified other impact via a large     iov_count value in a write request (bnc#940338).

  - CVE-2015-8709: kernel/ptrace.c in the Linux kernel     mishandled uid and gid mappings, which allowed local     users to gain privileges by establishing a user     namespace, waiting for a root process to enter that     namespace with an unsafe uid or gid, and then using the     ptrace system call. NOTE: the vendor states 'there is no     kernel bug here' (bnc#959709 bnc#960561).

  - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux     kernel did not properly manage the relationship between     a lock and a socket, which allowed local users to cause     a denial of service (deadlock) via a crafted sctp_accept     call (bnc#961509).

  - CVE-2015-8785: The fuse_fill_write_pages function in     fs/fuse/file.c in the Linux kernel allowed local users     to cause a denial of service (infinite loop) via a     writev system call that triggers a zero length for the     first segment of an iov (bnc#963765).

  - CVE-2015-8812: A use-after-free flaw was found in the     CXGB3 kernel driver when the network was considered to     be congested. This could be used by local attackers to     cause machine crashes or potentially code executuon     (bsc#966437).

  - CVE-2016-0723: Race condition in the tty_ioctl function     in drivers/tty/tty_io.c in the Linux kernel allowed     local users to obtain sensitive information from kernel     memory or cause a denial of service (use-after-free and     system crash) by making a TIOCGETD ioctl call during     processing of a TIOCSETD ioctl call (bnc#961500).

Update to latest upstream stable release, 4.3.3. This is a major kernel version rebase and testers should take care to ensure things are working as expected.

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

Update to latest upstream stable release, Linux v4.3.4. Elan touchpad fixes. ---- Update to 4.3.y stable series. Fixes across the tree.

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

The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c.
(CVE-2013-4312)

A race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 was found that allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call. (CVE-2016-0723)

A privilege-escalation vulnerability was discovered in the Linux kernel built with User Namespace (CONFIG_USER_NS) support. The flaw occurred when the ptrace() system call was used on a root-owned process to enter a user namespace. A privileged namespace user could exploit this flaw to potentially escalate their privileges on the system, outside the original namespace. (CVE-2015-8709)

net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not properly manage the relationship between a lock and a socket, which allows local users to cause a denial of service (deadlock) via a crafted sctp_accept call. (CVE-2015-8767)

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

  - CVE-2015-7513     It was discovered that a local user permitted to use the     x86 KVM subsystem could configure the PIT emulation to     cause a denial of service (crash).

  - CVE-2015-7550     Dmitry Vyukov discovered a race condition in the keyring     subsystem that allows a local user to cause a denial of     service (crash).

  - CVE-2015-8543     It was discovered that a local user permitted to create     raw sockets could cause a denial-of-service by     specifying an invalid protocol number for the socket.
    The attacker must have the CAP_NET_RAW capability.

  - CVE-2015-8550     Felix Wilhelm of ERNW discovered that the Xen PV backend     drivers may read critical data from shared memory     multiple times. This flaw can be used by a guest kernel     to cause a denial of service (crash) on the host, or     possibly for privilege escalation.

  - CVE-2015-8551 / CVE-2015-8552     Konrad Rzeszutek Wilk of Oracle discovered that the Xen     PCI backend driver does not adequately validate the     device state when a guest configures MSIs. This flaw can     be used by a guest kernel to cause a denial of service     (crash or disk space exhaustion) on the host.

  - CVE-2015-8569     Dmitry Vyukov discovered a flaw in the PPTP sockets     implementation that leads to an information leak to     local users.

  - CVE-2015-8575     David Miller discovered a flaw in the Bluetooth SCO     sockets implementation that leads to an information leak     to local users.

  - CVE-2015-8709     Jann Horn discovered a flaw in the permission checks for     use of the ptrace feature. A local user who has the     CAP_SYS_PTRACE capability within their own user     namespace could use this flaw for privilege escalation     if a more privileged process ever enters that user     namespace. This affects at least the LXC system.

In addition, this update fixes some regressions in the previous update :

  - #808293     A regression in the UDP implementation prevented     freeradius and some other applications from receiving     data.

  - #808602 / #808953

    A regression in the USB XHCI driver prevented use of     some devices in USB 3 SuperSpeed ports.

  - #808973

    A fix to the radeon driver interacted with an existing     bug to cause a crash at boot when using some AMD/ATI     graphics cards. This issue only affects wheezy.

    Felix Wilhelm discovered a race condition in the Xen paravirtualized drivers which can cause double fetch     vulnerabilities. An attacker in the paravirtualized guest could exploit this flaw to cause a denial of     service (crash the host) or potentially execute arbitrary code on the host. (CVE-2015-8550)

    Konrad Rzeszutek Wilk discovered the Xen PCI backend driver does not perform consistency checks on the     device's state. An attacker could exploit this flaw to cause a denial of service (NULL dereference) on the     host. (CVE-2015-8551)

    Konrad Rzeszutek Wilk discovered the Xen PCI backend driver does not perform consistency checks on the     device's state. An attacker could exploit this flaw to cause a denial of service by flooding the logging     system with WARN() messages causing the initial domain to exhaust disk space. (CVE-2015-8552)

    Jann Horn discovered a ptrace issue with user namespaces in the Linux kernel. The namespace owner could     potentially exploit this flaw by ptracing a root owned process entering the user namespace to elevate its     privileges and potentially gain access outside of the namespace. (http://bugs.launchpad.net/bugs/1527374,     CVE-2015-8709)
