The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel before     4.4 allows local users to gain privileges or cause a denial of service (memory corruption and system     crash) by detaching a device during an SG_IO ioctl call. (CVE-2015-8962)

Note that Nessus relies on the presence of the package as reported by the vendor.

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 :

  - An out-of-bounds memory access flaw was found in the     Linux kernel's system call auditing implementation. On     a system with existing audit rules defined, a local,     unprivileged user could use this flaw to leak kernel     memory to user space or, potentially, crash the     system.(CVE-2014-3917i1/4%0

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448i1/4%0

  - 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-2015-3339i1/4%0

  - Keberos 5 tickets being decoded when using the RXRPC     keys incorrectly assumes the size of a field. This     could lead to the size-remaining variable wrapping and     the data pointer going over the end of the buffer. This     could possibly lead to memory corruption and possible     privilege escalation.(CVE-2017-7482i1/4%0

  - The nfs_can_extend_write function in fs/nfs/write.c in     the Linux kernel before 3.13.3 relies on a write     delegation to extend a write operation without a     certain up-to-date verification, which allows local     users to obtain sensitive information from kernel     memory in opportunistic circumstances by writing to a     file in an NFS filesystem and then reading the same     file.(CVE-2014-2038i1/4%0

  - KVM in the Linux kernel before 4.8.12, when I/O APIC is     enabled, does not properly restrict the VCPU index,     which allows guest OS users to gain host OS privileges     or cause a denial of service (out-of-bounds array     access and host OS crash) via a crafted interrupt     request, related to arch/x86/kvm/ioapic.c and     arch/x86/kvm/ioapic.h.(CVE-2016-9777i1/4%0

  - 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-2014-8480i1/4%0

  - arch/x86/kernel/entry_32.S in the Linux kernel through     3.15.1 on 32-bit x86 platforms, when syscall auditing     is enabled and the sep CPU feature flag is set, allows     local users to cause a denial of service (OOPS and     system crash) via an invalid syscall number, as     demonstrated by number 1000.(CVE-2014-4508i1/4%0

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly restrict the mount     namespace, which allows local users to gain privileges     by mounting an overlayfs filesystem on top of a FUSE     filesystem, and then executing a crafted setuid     program.(CVE-2016-1576i1/4%0

  - A use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265i1/4%0

  - The drivers/uwb/uwbd.c in the Linux kernel, before     4.13.6, allows local users to cause a denial of service     (general protection fault and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16526i1/4%0

  - The Linux kernel was found vulnerable to a NULL pointer     dereference in the     drivers/net/phy/mdio-bcm-unimac.c:unimac_mdio_probe()     function caused by an unchecked return value from the     platform_get_resource() function. A successful flaw     exploitation can cause a system panic and a denial of     service. This flaw is believed not to be an attacker     triggerable as bad return value can be caused by     hardware misconfiguration.(CVE-2018-8043i1/4%0

  - A flaw was found in the Linux kernel SCSI subsystem,     which allowed a local user to gain privileges or cause     a denial of service (memory corruption and system     crash) by issuing an SG_IO ioctl call while a device     was being detached.(CVE-2015-8962i1/4%0

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-7913i1/4%0

  - drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver     in the Linux kernel through 4.0.5 does not ensure that     certain length values are sufficiently large, which     allows 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.(CVE-2015-4002i1/4%0

  - Race condition in the environ_read() function in     'fs/proc/base.c' in the Linux kernel before 4.5.4     allows local users to obtain sensitive information from     kernel memory by reading a '/proc/*/environ' file     during a process-setup time interval in which     environment-variable copying is     incomplete.(CVE-2016-7916i1/4%0

  - 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 through 4.0.5 allows     remote attackers to cause a denial of service (system     crash) or possibly execute arbitrary code via a crafted     packet.(CVE-2015-4001i1/4%0

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115i1/4%0

  - The evm_verify_hmac function in     security/integrity/evm/evm_main.c in the Linux kernel     before 4.5 does not properly copy data, which makes it     easier for local users to forge MAC values via a timing     side-channel attack.(CVE-2016-2085i1/4%0

  - A flaw was discovered in processing setsockopt for 32     bit processes on 64 bit systems. This flaw will allow     attackers to alter arbitrary kernel memory when     unloading a kernel module. This action is usually     restricted to root-privileged users but can also be     leveraged if the kernel is compiled with CONFIG_USER_NS     and CONFIG_NET_NS and the user is granted elevated     privileges.(CVE-2016-4997i1/4%0

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - An information-leak vulnerability was found in the     kernel when it truncated a file to a smaller size which     consisted of an inline extent that was compressed. The     data between the new file size and the old file size     was not discarded and the number of bytes used by the     inode were not correctly decremented, which gave the     wrong report for callers of the stat(2) syscall. This     wasted metadata space and allowed for the truncated     data to be leaked, and data corruption or loss to     occur. A caller of the clone ioctl could exploit this     flaw by using only standard file-system operations     without root access to read the truncated     data.(CVE-2015-8374)

  - A flaw was found in the Linux kernel's key management     system where it was possible for an attacker to     escalate privileges or crash the machine. If a user key     gets negatively instantiated, an error code is cached     in the payload area. A negatively instantiated key may     be then be positively instantiated by updating it with     valid data. However, the -i1/4zupdate key type method     must be aware that the error code may be     there.(CVE-2015-8539)

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's network subsystem handled socket     creation with an invalid protocol identifier. A local     user could use this flaw to crash the     system.(CVE-2015-8543)

  - An out-of-bounds flaw was found in the kernel, where     the length of the sockaddr parameter was not checked in     the pptp_bind() and pptp_connect() functions. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local system user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8569)

  - An out-of-bounds flaw was found in the kernel, where     the sco_sock_bind() function (bluetooth/sco) did not     check the length of its sockaddr parameter. As a     result, more kernel memory was copied out than     required, leaking information from the kernel stack     (including kernel addresses). A local user could     exploit this flaw to bypass kernel ASLR or leak other     information.(CVE-2015-8575)

  - The ovl_setattr function in fs/overlayfs/inode.c in the     Linux kernel through 4.3.3 attempts to merge distinct     setattr operations, which allows local users to bypass     intended access restrictions and modify the attributes     of arbitrary overlay files via a crafted     application.(CVE-2015-8660)

  - A NULL pointer dereference flaw was found in the Linux     kernel: the NFSv4.2 migration code improperly     initialized the kernel structure. A local,     authenticated user could use this flaw to cause a panic     of the NFS client (denial of service).(CVE-2015-8746)

  - A race condition flaw was found in the way the Linux     kernel's SCTP implementation handled sctp_accept()     during the processing of heartbeat timeout events. A     remote attacker could use this flaw to prevent further     connections to be accepted by the SCTP server running     on the system, resulting in a denial of     service.(CVE-2015-8767)

  - An infinite-loop flaw was found in the kernel. When a     local user calls the sys_writev syscall with a     specially crafted sequence of iov structs, the     fuse_fill_write_pages kernel function might never     terminate, instead continuing in a tight loop. This     process cannot be terminated and requires a     reboot.(CVE-2015-8785)

  - 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-2015-8787)

  - 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-2015-8812)

  - 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-2015-8816)

  - The ioresources_init function in kernel/resource.c in     the Linux kernel through 4.7, as used in Android before     2016-08-05 on Nexus 6 and 7 (2013) devices, uses weak     permissions for /proc/iomem, which allows local users     to obtain sensitive information by reading this file,     aka Android internal bug 28814213 and Qualcomm internal     bug CR786116. NOTE: the permissions may be intentional     in most non-Android contexts.(CVE-2015-8944)

  - '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-2015-8953)'

  - 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-2015-8956)

  - A flaw was found in the ext4 subsystem. This     vulnerability is a use after free vulnerability was     found in __ext4_journal_stop(). Attackers could abuse     this to allow any code which attempts to deal with the     journal failure to be mishandled or not fail at all.
    This could lead to data corruption or     crashes.(CVE-2015-8961)

  - A flaw was found in the Linux kernel SCSI subsystem,     which allowed a local user to gain privileges or cause     a denial of service (memory corruption and system     crash) by issuing an SG_IO ioctl call while a device     was being detached.(CVE-2015-8962)

  - Race condition in kernel/events/core.c in the Linux     kernel before 4.4 allows local users to gain privileges     or cause a denial of service via use-after-free     vulnerability by leveraging incorrect handling of an     swevent data structure during a CPU unplug     operation.(CVE-2015-8963)

  - The tty_set_termios_ldisc() function in     'drivers/tty/tty_ldisc.c' in the Linux kernel before     4.5 allows local users to obtain sensitive information     from kernel memory by reading a tty data     structure.(CVE-2015-8964)

  - The lrw_crypt() function in 'crypto/lrw.c' in the Linux     kernel before 4.5 allows local users to cause a system     crash and a denial of service by the NULL pointer     dereference via accept(2) system call for AF_ALG socket     without calling setkey() first to set a cipher     key.(CVE-2015-8970)

  - It was found that kernel/events/core.c in the Linux     kernel mishandles counter grouping, which allows local     users to gain privileges via a crafted application,     related to the perf_pmu_register and perf_event_open     functions.(CVE-2015-9004)

  - A use-after-free flaw was discovered in the Linux     kernel's tty subsystem, which allows for the disclosure     of uncontrolled memory location and possible kernel     panic. The information leak is caused by a race     condition when attempting to set and read the tty line     discipline. A local attacker could use the TIOCSETD     (via tty_set_ldisc ) to switch to a new line discipline     a concurrent call to a TIOCGETD ioctl performing a read     on a given tty could then access previously allocated     memory. Up to 4 bytes could be leaked when querying the     line discipline or the kernel could panic with a     NULL-pointer dereference.(CVE-2016-0723)

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

CVE-2012-6704, CVE-2016-9793

Eric Dumazet found that a local user with CAP_NET_ADMIN capability could set a socket's buffer size to be negative, leading to a denial of service or other security impact. Additionally, in kernel versions prior to 3.5, any user could do this if sysctl net.core.rmem_max was changed to a very large value.

CVE-2015-1350 / #770492

Ben Harris reported that local users could remove set-capability attributes from any file visible to them, allowing a denial of service.

CVE-2015-8962

Calvin Owens fouund that removing a SCSI device while it was being accessed through the SCSI generic (sg) driver led to a double- free, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could be exploited by local users with permision to access a SCSI device node.

CVE-2015-8963

Sasha Levin reported that hot-unplugging a CPU resulted in a use-after-free by the performance events (perf) subsystem, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could by exploited by any local user.

CVE-2015-8964

It was found that the terminal/serial (tty) subsystem did not reliably reset the terminal buffer state when the terminal line discipline was changed. This could allow a local user with access to a terminal device to read sensitive information from kernel memory.

CVE-2016-7097

Jan Kara found that changing the POSIX ACL of a file never cleared its set-group-ID flag, which should be done if the user changing it is not a member of the group-owner. In some cases, this would allow the user-owner of an executable to gain the privileges of the group-owner.

CVE-2016-7910

Vegard Nossum discovered that a memory allocation failure while handling a read of /proc/diskstats or /proc/partitions could lead to a use-after-free, possibly causing a denial of service (crash or memory corruption) or privilege escalation.

CVE-2016-7911

Dmitry Vyukov reported that a race between ioprio_get() and ioprio_set() system calls could result in a use-after-free, possibly causing a denial of service (crash) or leaking sensitive information.

CVE-2016-7915

Benjamin Tissoires found that HID devices could trigger an out-of- bounds memory access in the HID core. A physically present user could possibly use this for denial of service (crash) or to leak sensitive information.

CVE-2016-8399

Qidan He reported that the IPv4 ping socket implementation did not validate the length of packets to be sent. A user with permisson to use ping sockets could cause an out-of-bounds read, possibly resulting in a denial of service or information leak. However, on Debian systems no users have permission to create ping sockets by default.

CVE-2016-8633

Eyal Itkin reported that the IP-over-Firewire driver (firewire-net) did not validate the offset or length in link-layer fragmentation headers. This allowed a remote system connected by Firewire to write to memory after a packet buffer, leading to a denial of service (crash) or remote code execution.

CVE-2016-8645

Marco Grassi reported that if a socket filter (BPF program) attached to a TCP socket truncates or removes the TCP header, this could cause a denial of service (crash). This was exploitable by any local user.

CVE-2016-8655

Philip Pettersson found that the implementation of packet sockets (AF_PACKET family) had a race condition between enabling a transmit ring buffer and changing the version of buffers used, which could result in a use-after-free. A local user with the CAP_NET_ADMIN capability could exploit this for privilege escalation.

CVE-2016-9178

Al Viro found that a failure to read data from user memory might lead to a information leak on the x86 architecture (amd64 or i386).

CVE-2016-9555

Andrey Konovalov reported that the SCTP implementation does not validate 'out of the blue' packet chunk lengths early enough. A remote system able could use this to cause a denial of service (crash) or other security impact for systems using SCTP.

CVE-2016-9576, CVE-2016-10088

Dmitry Vyukov reported that using splice() with the SCSI generic driver led to kernel memory corruption. Local users with permision to access a SCSI device node could exploit this for privilege escalation.

CVE-2016-9756

Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or i386) did not correctly handle the failure of certain instructions that require software emulation on older processors. This could be exploited by guest systems to leak sensitive information or for denial of service (log spam).

CVE-2016-9794

Baozeng Ding reported a race condition in the ALSA (sound) subsystem that could result in a use-after-free. Local users with access to a PCM sound device could exploit this for denial of service (crash or memory corruption) or other security impact.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-1. This version also includes bug fixes from upstream version 3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
Finally, this version adds the option to mitigate security issues in the performance events (perf) subsystem by disabling use by unprivileged users. This can be done by setting sysctl kernel.perf_event_paranoid=3.

For Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1 which will be included in the next point release (8.6).

We recommend that you upgrade your linux packages.
