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 :

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions past bounds check. The flaw     relies on the presence of a precisely-defined     instruction sequence in the privileged code and the     fact that memory writes occur to an address which     depends on the untrusted value. Such writes cause an     update into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to influence speculative execution     and/or read privileged memory by conducting targeted     cache side-channel attacks.(CVE-2018-3693)

  - A flaw named SegmentSmack was found in the way the     Linux kernel handled specially crafted TCP packets. A     remote attacker could use this flaw to trigger time and     calculation expensive calls to tcp_collapse_ofo_queue()     and tcp_prune_ofo_queue() functions by sending     specially modified packets within ongoing TCP sessions     which could lead to a CPU saturation and hence a denial     of service on the system. Maintaining the denial of     service condition requires continuous two-way TCP     sessions to a reachable open port, thus the attacks     cannot be performed using spoofed IP     addresses.(CVE-2018-5390)

  - It was found that the raw midi kernel driver does not     protect against concurrent access which leads to a     double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)

  - Integer overflow in the aio_setup_single_vector     function in fs/aio.c in the Linux kernel 4.0 allows     local users to cause a denial of service or possibly     have unspecified other impact via a large AIO iovec.
    NOTE: this vulnerability exists because of a     CVE-2012-6701 regression.(CVE-2015-8830)

  - A flaw was found in the Linux networking subsystem     where a local attacker with CAP_NET_ADMIN capabilities     could cause an out-of-bounds memory access by creating     a smaller-than-expected ICMP header and sending to its     destination via sendto().(CVE-2016-8399)

  - Out-of-bounds kernel heap access vulnerability was     found in xfrm, kernel's IP framework for transforming     packets. An error dealing with netlink messages from an     unprivileged user leads to arbitrary read/write and     privilege escalation.(CVE-2017-7184)

  - The Linux kernel was found to be vulnerable to a NULL     pointer dereference bug in the __netlink_ns_capable()     function in the net/netlink/af_netlink.c file. A local     attacker could exploit this when a net namespace with a     netnsid is assigned to cause a kernel panic and a     denial of service.i1/4^CVE-2018-14646i1/4%0

  - A flaw was found where the kernel truncated the value     used to indicate the size of a buffer which it would     later become zero using an untruncated value. This can     corrupt memory outside of the original     allocation.(CVE-2017-9725)

  - A bug in the 32-bit compatibility layer of the ioctl     handling code of the v4l2 video driver in the Linux     kernel has been found. A memory protection mechanism     ensuring that user-provided buffers always point to a     userspace memory were disabled, allowing destination     address to be in a kernel space. This flaw could be     exploited by an attacker to overwrite a kernel memory     from an unprivileged userspace process, leading to     privilege escalation.(CVE-2017-13166)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5754 relies on the     fact that, on impacted microprocessors, during     speculative execution of instruction permission faults,     exception generation triggered by a faulting access is     suppressed until the retirement of the whole     instruction block. In a combination with the fact that     memory accesses may populate the cache even when the     block is being dropped and never committed (executed),     an unprivileged local attacker could use this flaw to     read privileged (kernel space) memory by conducting     targeted cache side-channel attacks. Note:
    CVE-2017-5754 affects Intel x86-64 microprocessors. AMD     x86-64 microprocessors are not affected by this     issue.(CVE-2017-5754)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5753 triggers the     speculative execution by performing a bounds-check     bypass. It relies on the presence of a     precisely-defined instruction sequence in the     privileged code as well as the fact that memory     accesses may cause allocation into the microprocessor's     data cache even for speculatively executed instructions     that never actually commit (retire). As a result, an     unprivileged attacker could use this flaw to cross the     syscall boundary and read privileged memory by     conducting targeted cache side-channel     attacks.(CVE-2017-5753)

  - A flaw was found in the Linux kernel's skcipher     component, which affects the skcipher_recvmsg function.
    Attackers using a specific input can lead to a     privilege escalation.i1/4^CVE-2017-13215i1/4%0

  - The tcpmss_mangle_packet function in     net/netfilter/xt_TCPMSS.c in the Linux kernel before     4.11, and 4.9.x before 4.9.36, allows remote attackers     to cause a denial of service (use-after-free and memory     corruption) or possibly have unspecified other impact     by leveraging the presence of xt_TCPMSS in an iptables     action. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.i1/4^CVE-2017-18017i1/4%0

  - A kernel data leak due to an out-of-bound read was     found in the Linux kernel in     inet_diag_msg_sctp{,l}addr_fill() and     sctp_get_sctp_info() functions present since version     4.7-rc1 through version 4.13. A data leak happens when     these functions fill in sockaddr data structures used     to export socket's diagnostic information. As a result,     up to 100 bytes of the slab data could be leaked to a     userspace.i1/4^CVE-2017-7558i1/4%0

  - Use-after-free vulnerability in the snd_pcm_info()     function in the ALSA subsystem in the Linux kernel     allows attackers to induce a kernel memory corruption     and possibly crash or lock up a system. Due to the     nature of the flaw, a privilege escalation cannot be     fully ruled out, although we believe it is     unlikely.i1/4^CVE-2017-0861i1/4%0

  - Improper validation in the bnx2x network card driver of     the Linux kernel version 4.15 can allow for denial of     service (DoS) attacks via a packet with a gso_size     larger than ~9700 bytes. Untrusted guest VMs can     exploit this vulnerability in the host machine, causing     a crash in the network card.i1/4^CVE-2018-1000026i1/4%0

  - An error in the '_sctp_make_chunk()' function     (net/sctp/sm_make_chunk.c) when handling SCTP, packet     length can be exploited by a malicious local user to     cause a kernel crash and a DoS.i1/4^CVE-2018-5803i1/4%0
