The openSUSE Leap 42.1 kernel was updated to 4.1.31 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2016-2847: fs/pipe.c in the Linux kernel did not     limit the amount of unread data in pipes, which allowed     local users to cause a denial of service (memory     consumption) by creating many pipes with non-default     sizes (bnc#970948).

  - CVE-2016-3134: The netfilter subsystem in the Linux     kernel did not validate certain offset fields, which     allowed local users to gain privileges or cause a denial     of service (heap memory corruption) via an     IPT_SO_SET_REPLACE setsockopt call (bnc#971126).

  - CVE-2016-3156: The IPv4 implementation in the Linux     kernel mishandled destruction of device objects, which     allowed guest OS users to cause a denial of service     (host OS networking outage) by arranging for a large     number of IP addresses (bnc#971360).

  - CVE-2016-4485: The llc_cmsg_rcv function in     net/llc/af_llc.c in the Linux kernel did not initialize     a certain data structure, which allowed attackers to     obtain sensitive information from kernel stack memory by     reading a message (bnc#978821).

  - CVE-2016-4580: The x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel did not     properly initialize a certain data structure, which     allowed attackers to obtain sensitive information from     kernel stack memory via an X.25 Call Request     (bnc#981267).

  - CVE-2016-4805: Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     allowed 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 (bnc#980371).

  - CVE-2016-4951: The tipc_nl_publ_dump function in     net/tipc/socket.c in the Linux kernel did not verify     socket existence, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     dumpit operation (bnc#981058).

  - CVE-2015-8787: The nf_nat_redirect_ipv4 function in     net/netfilter/nf_nat_redirect.c in the Linux kernel     allowed remote attackers to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact by sending certain IPv4     packets to an incompletely configured interface, a     related issue to CVE-2003-1604 (bnc#963931).

  - CVE-2016-4569: The snd_timer_user_params function in     sound/core/timer.c in the Linux kernel did not     initialize a certain data structure, which allowed local     users to obtain sensitive information from kernel stack     memory via crafted use of the ALSA timer interface     (bnc#979213).

  - CVE-2016-4578: sound/core/timer.c in the Linux kernel     did not initialize certain r1 data structures, which     allowed local users to obtain sensitive information from     kernel stack memory via crafted use of the ALSA timer     interface, related to the (1) snd_timer_user_ccallback     and (2) snd_timer_user_tinterrupt functions     (bnc#979879).

  - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt     implementation in the netfilter subsystem in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read) or possibly obtain sensitive     information from kernel heap memory by leveraging     in-container root access to provide a crafted offset     value that leads to crossing a ruleset blob boundary     (bnc#986362 986365 990058).

  - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel     did not properly determine the rate of challenge ACK     segments, which made it easier for man-in-the-middle     attackers to hijack TCP sessions via a blind in-window     attack (bnc#989152).

  - CVE-2016-1237: nfsd in the Linux kernel allowed local     users to bypass intended file-permission restrictions by     setting a POSIX ACL, related to nfs2acl.c, nfs3acl.c,     and nfs4acl.c (bnc#986570).

The following non-security bugs were fixed :

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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 offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370i1/4%0

  - Integer overflow in the LZ4 algorithm implementation,     as used in Yann Collet LZ4 before r118 and in the     lz4_uncompress function in lib/lz4/lz4_decompress.c in     the Linux kernel before 3.15.2, on 32-bit platforms     might allow context-dependent attackers to cause a     denial of service (memory corruption) or possibly have     unspecified other impact via a crafted Literal Run that     would be improperly handled by programs not complying     with an API limitation, a different vulnerability than     CVE-2014-4715.(CVE-2014-4611i1/4%0

  - The replace_map_fd_with_map_ptr function in     kernel/bpf/verifier.c in the Linux kernel before 4.5.5     does not properly maintain an fd data structure, which     allows local users to gain privileges or cause a denial     of service (use-after-free) via crafted BPF     instructions that reference an incorrect file     descriptor.(CVE-2016-4557i1/4%0

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider     the maximum number of configurations and interfaces     before attempting to release resources. This allows     local users to cause a denial of service, due to     out-of-bounds write access, or possibly have     unspecified other impact via a crafted USB device. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-17558i1/4%0

  - The cdrom_ioctl_media_changed function in     drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6     allows local attackers to use a incorrect bounds check     in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read     out kernel memory.(CVE-2018-10940i1/4%0

  - It was found that the parse_rock_ridge_inode_internal()     function of the Linux kernel's ISOFS implementation did     not correctly check relocated directories when     processing Rock Ridge child link (CL) tags. An attacker     with physical access to the system could use a     specially crafted ISO image to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-5471i1/4%0

  - A flaw was found in the Linux kernel's implementation     of Unix sockets. A server polling for client-socket     data could put the peer socket on a wait list the peer     socket could then close the connection, making the     reference on the wait list no longer valid. This could     lead to bypassing the permissions on a Unix socket and     packets being injected into the stream, and could also     panic the machine (denial of service).(CVE-2013-7446i1/4%0

  - The do_check function in kernel/bpf/verifier.c in the     Linux kernel before 4.11.1 does not make the     allow_ptr_leaks value available for restricting the     output of the print_bpf_insn function, which allows     local users to obtain sensitive address information via     crafted bpf system calls.(CVE-2017-9150i1/4%0

  - The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x     and 4.x, as used in Qualcomm Innovation Center (QuIC)     Android contributions for MSM devices and other     products, does not verify authorization for private SET     IOCTL calls, which allows attackers to gain privileges     via a crafted application, related to     wlan_hdd_hostapd.c and     wlan_hdd_wext.c.(CVE-2015-0571i1/4%0

  - arch/arm64/kvm/guest.c in KVM in the Linux kernel     before 4.18.12 on the arm64 platform mishandles the     KVM_SET_ON_REG ioctl. This is exploitable by attackers     who can create virtual machines. An attacker can     arbitrarily redirect the hypervisor flow of control     (with full register control). An attacker can also     cause a denial of service (hypervisor panic) via an     illegal exception return. This occurs because of     insufficient restrictions on userspace access to the     core register file, and because PSTATE.M validation     does not prevent unintended execution     modes.(CVE-2018-18021i1/4%0

  - A resource-exhaustion vulnerability was found in the     kernel, where an unprivileged process could allocate     and accumulate far more file descriptors than the     process' limit. A local, unauthenticated user could     exploit this flaw by sending file descriptors over a     Unix socket and then closing them to keep the process'     fd count low, thereby creating kernel-memory or     file-descriptors exhaustion (denial of     service).(CVE-2016-2550i1/4%0

  - 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.(CVE-2013-7263i1/4%0

  - It is possible for a single process to cause an OOM     condition by filling large pipes with data that are     never read. A typical process filling 4096 pipes with 1     MB of data will use 4 GB of memory and there can be     multiple such processes, up to a     per-user-limit.(CVE-2016-2847i1/4%0

  - The __get_user_asm_ex macro in     arch/x86/include/asm/uaccess.h in the Linux kernel     before 4.7.5 does not initialize a certain integer     variable, which allows local users to obtain sensitive     information from kernel stack memory by triggering     failure of a get_user_ex call.(CVE-2016-9178i1/4%0

  - It was found that the x86 ISA (Instruction Set     Architecture) is prone to a denial of service attack     inside a virtualized environment in the form of an     infinite loop in the microcode due to the way     (sequential) delivering of benign exceptions such as     #DB (debug exception) is handled. A privileged user     inside a guest could use this flaw to create denial of     service conditions on the host kernel.(CVE-2015-8104i1/4%0

  - The Direct Rendering Manager (DRM) subsystem in the     Linux kernel through 4.x mishandles requests for     Graphics Execution Manager (GEM) objects, which allows     context-dependent attackers to cause a denial of     service (memory consumption) via an application that     processes graphics data, as demonstrated by JavaScript     code that creates many CANVAS elements for rendering by     Chrome or Firefox.(CVE-2013-7445i1/4%0

  - A flaw was found in the Linux kernel which does not     initialize certain data structures used by DMA transfer     on ARM64 based systems. This could allow local users to     obtain sensitive information from kernel memory by     triggering a dma_mmap call and reconstructing the     data.(CVE-2015-8950i1/4%0

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or     use-after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be     fully ruled out, although we believe it is     unlikely.(CVE-2017-10661i1/4%0

  - The sg_ioctl() function in 'drivers/scsi/sg.c' in the     Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows     local users to obtain sensitive information from     uninitialized kernel heap-memory locations via an     SG_GET_REQUEST_TABLE ioctl call for     '/dev/sg0'.(CVE-2017-14991i1/4%0

  - A race condition in the ip4_datagram_release_cb     function in net/ipv4/datagram.c in the Linux kernel     allows local users to gain privileges or cause a denial     of service (use-after-free) by leveraging incorrect     expectations about locking during multithreaded access     to internal data structures for IPv4 UDP     sockets.(CVE-2014-9914i1/4%0

The openSUSE Leap 42.1 kernel was updated to 4.1.26 to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2016-1583: Prevent the usage of mmap when the lower     file system does not allow it. This could have lead to     local privilege escalation when ecryptfs-utils was     installed and /sbin/mount.ecryptfs_private was setuid     (bsc#983143).

  - CVE-2016-4565: The InfiniBand (aka IB) stack in the     Linux kernel incorrectly relies on the write system     call, which allows local users to cause a denial of     service (kernel memory write operation) or possibly have     unspecified other impact via a uAPI interface.
    (bsc#979548)

  - CVE-2016-4805: Use-after-free vulnerability in     drivers/net/ppp/ppp_generic.c in the Linux kernel     allowed 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. (bsc#980371).

  - CVE-2016-4951: The tipc_nl_publ_dump function in     net/tipc/socket.c in the Linux kernel did not verify     socket existence, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     dumpit operation. (bsc#981058).

  - CVE-2016-5244: An information leak vulnerability in     function rds_inc_info_copy of file net/rds/recv.c was     fixed that might have leaked kernel stack data.
    (bsc#983213).

  - CVE-2016-4580: The x25_negotiate_facilities function in     net/x25/x25_facilities.c in the Linux kernel did not     properly initialize a certain data structure, which     allowed attackers to obtain sensitive information from     kernel stack memory via an X.25 Call Request.
    (bsc#981267).

  - 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-2016-3134: The netfilter subsystem in the Linux     kernel did not validate certain offset fields, which     allowed local users to gain privileges or cause a denial     of service (heap memory corruption) via an     IPT_SO_SET_REPLACE setsockopt call (bnc#971126).

  - CVE-2016-3672: The arch_pick_mmap_layout function in     arch/x86/mm/mmap.c in the Linux kernel did not properly     randomize the legacy base address, which made it easier     for local users to defeat the intended restrictions on     the ADDR_NO_RANDOMIZE flag, and bypass the ASLR     protection mechanism for a setuid or setgid program, by     disabling stack-consumption resource limits     (bnc#974308).

  - CVE-2016-4482: A kernel information leak in the usbfs     devio connectinfo was fixed, which could expose kernel     stack memory to userspace. (bnc#978401).

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

The Linux kernel did not properly suppress hugetlbfs support in x86 PV guests, which could allow local PV guest users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. (CVE-2016-3961 / XSA-174)

A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system. (CVE-2016-0758)

Multiple race conditions in the ext4 filesystem implementation in the Linux kernel before 4.5 allow local users to cause a denial of service (disk corruption) by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling. (CVE-2015-8839)
