Additional Changes :

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-003091 advisory.

    The rngapi_reset function in crypto/rng.c in the Linux kernel before 4.2 allows attackers to cause a     denial of service (NULL pointer dereference).

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.

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

  - The rngapi_reset function in crypto/rng.c in the Linux kernel before 4.2 allows attackers to cause a     denial of service (NULL pointer dereference). (CVE-2017-15116)

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 :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A buffer overflow was     discovered in tpacket_rcv() function in the Linux     kernel since v4.6-rc1 through v4.13. A number of     socket-related syscalls can be made to set up a     configuration when each packet received by a network     interface can cause writing up to 10 bytes to a kernel     memory outside of a kernel buffer. This can cause     unspecified kernel data corruption effects, including     damage of in-memory and on-disk XFS     data.(CVE-2017-14497)The qmi_wwan_bind function in     driverset/usb/qmi_wwan.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (divide-by-zero error and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16650)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)A race condition     flaw was found in the way the Linux kernel's KVM     subsystem handled PIT (Programmable Interval Timer)     emulation. A guest user who has access to the PIT I/O     ports could use this flaw to crash the     host.(CVE-2014-3611)The Linux kernel is vulnerable to a     memory leak in the     driverset/wireless/mac80211_hwsim.c:hwsim_new_radio_nl(     ) function. An attacker could exploit this to cause a     potential denial of service.(CVE-2018-8087)An integer     underflow flaw was found in the way the Linux kernel's     Stream Control Transmission Protocol (SCTP)     implementation processed certain COOKIE_ECHO packets.
    By sending a specially crafted SCTP packet, a remote     attacker could use this flaw to prevent legitimate     connections to a particular SCTP server socket to be     made.(CVE-2014-4667)The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16536)The     snd_usb_create_streams function in sound/usb/card.c in     the Linux kernel, before 4.13.6, allows local users to     cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16529)A flaw was     found in the Linux kernel's random number generator     API. A null pointer dereference in the rngapi_reset     function may result in denial of service, crashing the     system.(CVE-2017-15116)The __netlink_deliver_tap_skb     function in netetlink/af_netlink.c in the Linux kernel,     through 4.14.4, does not restrict observations of     Netlink messages to a single net namespace, when     CONFIG_NLMON is enabled. This allows local users to     obtain sensitive information by leveraging the     CAP_NET_ADMIN capability to sniff an nlmon interface     for all Netlink activity on the     system.(CVE-2017-17449)arch/arm64/kernel/perf_event.c     in the Linux kernel before 4.1 on arm64 platforms     allows local users to gain privileges or cause a denial     of service (invalid pointer dereference) via vectors     involving events that are mishandled during a span of     multiple HW PMUs.(CVE-2015-8955)The aac_compat_ioctl     function in drivers/scsi/aacraid/linit.c in the Linux     kernel before 3.11.8 does not require the CAP_SYS_RAWIO     capability, which allows local users to bypass intended     access restrictions via a crafted ioctl     call.(CVE-2013-6383)Linux kernel before version     4.16-rc7 is vulnerable to a null pointer dereference in     dccp_write_xmit() function in net/dccp/output.c in that     allows a local user to cause a denial of service by a     number of certain crafted system     calls.(CVE-2018-1130)The Linux kernel is vulerable to a     use-after-free flaw when Transformation User     configuration interface(CONFIG_XFRM_USER) compile-time     configuration were enabled. This vulnerability occurs     while closing a xfrm netlink socket in     xfrm_dump_policy_done. A user/process could abuse this     flaw to potentially escalate their privileges on a     system.(CVE-2017-16939)A vulnerability was found in the     Linux kernel in function rds_inc_info_copy of file     net/rds/recv.c. The last field 'flags' of object     'minfo' is not initialized. This can leak data     previously at the flags location to     userspace.(CVE-2016-5244)A flaw was found in the     kernel's ACPI interpreter when it does not flush the     operand cache and causes a kernel stack dump. This     allows local users to obtain sensitive information from     kernel memory and bypass the KASLR protection     mechanism.(CVE-2017-13693)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)The xfs_bmap_extents_to_btree     function in fs/xfs/libxfs/xfs_bmap.c in the Linux     kernel through 4.16.3 allows local users to cause a     denial of service (xfs_bmapi_write NULL pointer     dereference) via a crafted xfs     image.(CVE-2018-10323)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)The IPv6     fragmentation implementation in the Linux kernel does     not consider that the nexthdr field may be associated     with an invalid option, which allows local users to     cause a denial of service (out-of-bounds read and BUG)     or possibly have unspecified other impact via crafted     socket and send system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9074)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:0676 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * kernel: Buffer overflow in firewire driver via crafted incoming packets (CVE-2016-8633, Important)
