The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000681 advisory.

    A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the     Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a     Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in     a NULL pointer dereference and system crash.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue 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 installation on the remote host is affected by the following vulnerabilities :

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754)

  - A flaw was found in the Linux kernel's implementation     of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt()     system call. Users with non-namespace CAP_NET_ADMIN are     able to trigger this call and create a situation in     which the sockets sendbuff data size could be negative.
    This could adversely affect memory allocations and     create situations where the system could crash or cause     memory corruption.(CVE-2016-9793)

  - A use-after-free vulnerability was found in ALSA pcm     layer, which allows local users to cause a denial of     service, memory corruption, or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9794)

  - A double free vulnerability was found in netlink_dump,     which could cause a denial of service or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9806)

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     can use this issue to crash the     system.(CVE-2017-1000111)

  - An exploitable memory corruption flaw was found in the     Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data()     when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw     can be exploited to gain root     privileges.(CVE-2017-1000112)

  - A stack buffer overflow flaw was found in the way the     Bluetooth subsystem of the Linux kernel processed     pending L2CAP configuration responses from a client. On     systems with the stack protection feature enabled in     the kernel (CONFIG_CC_STACKPROTECTOR=y, which is     enabled on all architectures other than s390x and     ppc64le), an unauthenticated attacker able to initiate     a connection to a system via Bluetooth could use this     flaw to crash the system. Due to the nature of the     stack protection feature, code execution cannot be     fully ruled out, although we believe it is unlikely. On     systems without the stack protection feature (ppc64le     the Bluetooth modules are not built on s390x), an     unauthenticated attacker able to initiate a connection     to a system via Bluetooth could use this flaw to     remotely execute arbitrary code on the system with ring     0 (kernel) privileges.(CVE-2017-1000251)

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (i1/4z1024) index value.(CVE-2017-1000252)

  - A flaw was found in the way memory was being allocated     on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were     adjacent to each other, an attacker could use this flaw     to jump over the stack guard gap, cause controlled     memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on     the system. This is a kernel-side mitigation which     increases the stack guard gap size from one page to 1     MiB to make successful exploitation of this issue more     difficult.(CVE-2017-1000364)

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIMIT_INFINITY, but does not take the     argument and environment pointers into account, which     allows attackers to bypass this     limitation.(CVE-2017-1000365)

  - 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-2017-1000370)

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can     be sent to an attacker leaking data in kernel address     space.(CVE-2017-1000410)

  - 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-2017-10661)

  - Memory leak in the virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel through 4.11.8 allows attackers to cause a     denial of service (memory consumption) by triggering     object-initialization failures.(CVE-2017-10810)

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911)

  - A use-after-free flaw was found in the Netlink     functionality of the Linux kernel networking subsystem.
    Due to the insufficient cleanup in the mq_notify     function, a local attacker could potentially use this     flaw to escalate their privileges on the     system.(CVE-2017-11176)

  - 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-2017-11473)

  - The xfrm_migrate() function in the     net/xfrm/xfrm_policy.c file in the Linux kernel built     with CONFIG_XFRM_MIGRATE does not verify if the dir     parameter is less than XFRM_POLICY_MAX. This allows a     local attacker to cause a denial of service     (out-of-bounds access) or possibly have unspecified     other impact by sending a XFRM_MSG_MIGRATE netlink     message. This flaw is present in the Linux kernel since     an introduction of XFRM_MSG_MIGRATE in 2.6.21-rc1, up     to 4.13-rc3.(CVE-2017-11600)

  - A security flaw was discovered in     nl80211_set_rekey_data() function in the Linux kernel     since v3.1-rc1 through v4.13. This function does not     check whether the required attributes are present in a     netlink request. This request can be issued by a user     with CAP_NET_ADMIN privilege and may result in NULL     dereference and a system crash.(CVE-2017-12153)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a     nested visualization setup, L2 guest user could use     this flaw to potentially crash the host(L0) resulting     in DoS.(CVE-2017-12154)

  - The Linux kernel built with the KVM visualization     support (CONFIG_KVM), with nested visualization(nVMX)     feature enabled (nested=1), was vulnerable to a stack     buffer overflow issue. The vulnerability could occur     while traversing guest page table entries to resolve     guest virtual address(gva). An L1 guest could use this     flaw to crash the host kernel resulting in denial of     service (DoS) or potentially execute arbitrary code on     the host to gain privileges on the     system.(CVE-2017-12188)

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-1000252: The KVM subsystem in the Linux kernel     allowed guest OS users to cause a denial of service     (assertion failure, and hypervisor hang or crash) via an     out-of bounds guest_irq value, related to     arch/x86/kvm/vmx.c and virt/kvm/eventfd.c (bnc#1058038).

  - CVE-2017-11472: The acpi_ns_terminate() function in     drivers/acpi/acpica/nsutils.c in the Linux kernel did     not flush the operand cache and causes a kernel stack     dump, which allowed local users to obtain sensitive     information from kernel memory and bypass the KASLR     protection mechanism (in the kernel through 4.9) via a     crafted ACPI table (bnc#1049580).

  - CVE-2017-12134: The xen_biovec_phys_mergeable function     in drivers/xen/biomerge.c in Xen might allow local OS     guest users to corrupt block device data streams and     consequently obtain sensitive memory information, cause     a denial of service, or gain host OS privileges by     leveraging incorrect block IO merge-ability calculation     (bnc#1051790 bsc#1053919).

  - CVE-2017-12153: A security flaw was discovered in the     nl80211_set_rekey_data() function in     net/wireless/nl80211.c in the Linux kernel This function     did not check whether the required attributes are     present in a Netlink request. This request can be issued     by a user with the CAP_NET_ADMIN capability and may     result in a NULL pointer dereference and system crash     (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in     arch/x86/kvm/vmx.c in the Linux kernel did not ensure     that the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allowed KVM L2 guest     OS users to obtain read and write access to the hardware     CR8 register (bnc#1058507).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)     allowed reinstallation of the Group Temporal Key (GTK)     during the group key handshake, allowing an attacker     within radio range to replay frames from access points     to clients (bnc#1056061 1063479 1063667 1063671).

  - CVE-2017-14051: An integer overflow in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption and system crash) by leveraging root access     (bnc#1056588).

  - CVE-2017-14106: The tcp_disconnect function in     net/ipv4/tcp.c in the Linux kernel allowed local users     to cause a denial of service (__tcp_select_window     divide-by-zero error and system crash) by triggering a     disconnect within a certain tcp_recvmsg code path     (bnc#1056982).

  - CVE-2017-14489: The iscsi_if_rx function in     drivers/scsi/scsi_transport_iscsi.c in the Linux kernel     allowed local users to cause a denial of service (panic)     by leveraging incorrect length validation (bnc#1059051).

  - CVE-2017-15265: Use-after-free vulnerability in the     Linux kernel before 4.14-rc5 allowed local users to have     unspecified impact via vectors related to /dev/snd/seq     (bnc#1062520).

  - CVE-2017-15649: net/packet/af_packet.c in the Linux     kernel allowed local users to gain privileges via     crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind) that     leads to a use-after-free, a different vulnerability     than CVE-2017-6346 (bnc#1064388).

    A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the     Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a     Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in     a NULL pointer dereference and system crash.

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

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

  - CVE-2017-7518     Andy Lutomirski discovered that KVM is prone to an     incorrect debug exception (#DB) error occurring while     emulating a syscall instruction. A process inside a     guest can take advantage of this flaw for privilege     escalation inside a guest.

  - CVE-2017-7558 (stretch only)     Stefano Brivio of Red Hat discovered that the SCTP     subsystem is prone to a data leak vulnerability due to     an out-of-bounds read flaw, allowing to leak up to 100     uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)     Dmitry Vyukov of Google reported that the timerfd     facility does not properly handle certain concurrent     operations on a single file descriptor. This allows a     local attacker to cause a denial of service or     potentially execute arbitrary code.

  - CVE-2017-11600     Bo Zhang reported that the xfrm subsystem does not     properly validate one of the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     can use this to cause a denial of service or potentially     to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229     Jan H. Schoenherr of Amazon discovered that when Linux     is running in a Xen PV domain on an x86 system, it may     incorrectly merge block I/O requests. A buggy or     malicious guest may trigger this bug in dom0 or a PV     driver domain, causing a denial of service or     potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying   back-end block devices, e.g.:echo 2 >   /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)     Adrian Salido of Google reported a race condition in     access to the'driver_override' attribute for platform     devices in sysfs. If unprivileged users are permitted to     access this attribute, this might allow them to gain     privileges.

  - CVE-2017-12153     Bo Zhang reported that the cfg80211 (wifi) subsystem     does not properly validate the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     (in any user namespace with a wifi device) can use this     to cause a denial of service.

  - CVE-2017-12154     Jim Mattson of Google reported that the KVM     implementation for Intel x86 processors did not     correctly handle certain nested hypervisor     configurations. A malicious guest (or nested guest in a     suitable L1 hypervisor) could use this for denial of     service.

  - CVE-2017-14106     Andrey Konovalov discovered that a user-triggerable     division by zero in the tcp_disconnect() function could     result in local denial of service.

  - CVE-2017-14140     Otto Ebeling reported that the move_pages() system call     performed insufficient validation of the UIDs of the     calling and target processes, resulting in a partial     ASLR bypass. This made it easier for local users to     exploit vulnerabilities in programs installed with the     set-UID permission bit set.

  - CVE-2017-14156     'sohu0106' reported an information leak in the atyfb     video driver. A local user with access to a framebuffer     device handled by this driver could use this to obtain     sensitive information.

  - CVE-2017-14340     Richard Wareing discovered that the XFS implementation     allows the creation of files with the 'realtime' flag on     a filesystem with no realtime device, which can result     in a crash (oops). A local user with access to an XFS     filesystem that does not have a realtime device can use     this for denial of service.

  - CVE-2017-14489     ChunYu Wang of Red Hat discovered that the iSCSI     subsystem does not properly validate the length of a     netlink message, leading to memory corruption. A local     user with permission to manage iSCSI devices can use     this for denial of service or possibly to execute     arbitrary code.

  - CVE-2017-14497 (stretch only)     Benjamin Poirier of SUSE reported that vnet headers are     not properly handled within the tpacket_rcv() function     in the raw packet (af_packet) feature. A local user with     the CAP_NET_RAW capability can take advantage of this     flaw to cause a denial of service (buffer overflow, and     disk and memory corruption) or have other impact.

  - CVE-2017-1000111     Andrey Konovalov of Google reported a race condition in     the raw packet (af_packet) feature. Local users with the     CAP_NET_RAW capability can use this for denial of     service or possibly to execute arbitrary code.

  - CVE-2017-1000112     Andrey Konovalov of Google reported a race condition     flaw in the UDP Fragmentation Offload (UFO) code. A     local user can use this flaw for denial of service or     possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881     Armis Labs discovered that the Bluetooth subsystem does     not properly validate L2CAP configuration responses,     leading to a stack-based buffer overflow. This is one of     several vulnerabilities dubbed 'Blueborne'. A nearby     attacker can use this to cause a denial of service or     possibly to execute arbitrary code on a system with     Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)     Jan H. Schoenherr of Amazon reported that the KVM     implementation for Intel x86 processors did not     correctly validate interrupt injection requests. A local     user with permission to use KVM could use this for     denial of service.

  - CVE-2017-1000370     The Qualys Research Labs reported that a large argument     or environment list can result in ASLR bypass for 32-bit     PIE binaries.

  - CVE-2017-1000371     The Qualys Research Labs reported that a large argument     or environment list can result in a stack/heap clash for     32-bit PIE binaries.

  - CVE-2017-1000380     Alexander Potapenko of Google reported a race condition     in the ALSA (sound) timer driver, leading to an     information leak. A local user with permission to access     sound devices could use this to obtain sensitive     information.

Debian disables unprivileged user namespaces by default, but if they are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited by any local user.
