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

  - Microarchitectural Store Buffer Data Sampling (MSBDS):
    Store buffers on some microprocessors utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access. A list of impacted products     can be found here:

  - Microarchitectural Data Sampling Uncacheable Memory     (MDSUM): Uncacheable memory on some microprocessors     utilizing speculative execution may allow an     authenticated user to potentially enable information     disclosure via a side channel with local access. A list     of impacted products can be found here:

  - Microarchitectural Fill Buffer Data Sampling (MFBDS):
    Fill buffers on some microprocessors utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access. A list of impacted products     can be found here:
    https://www.intel.com/content/dam/www/public/us/en/docu     ments/corporate-information/SA00233-microcode-update-gu     idance_05132019.pdf(CVE-2018-12130)

  - Microarchitectural Load Port Data Sampling (MLPDS):
    Load ports on some microprocessors utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access. A list of impacted products     can be found here:
    https://www.intel.com/content/dam/www/public/us/en/docu     ments/corporate-information/SA00233-microcode-update-gu     idance_05132019.pdf(CVE-2018-12127)

  - An incorrect permissions check was discovered in     libvirt 4.8.0 and above. The readonly permission was     allowed to invoke APIs depending on the guest agent,     which could lead to potentially disclosing unintended     information or denial of service by causing libvirt to     block.(CVE-2019-3886)

  - libvirt version before 4.2.0-rc1 is vulnerable to a     resource exhaustion as a result of an incomplete fix     for CVE-2018-5748 that affects QEMU monitor but now     also triggered via QEMU guest agent.(CVE-2018-1064)

  - qemu/qemu_monitor.c in libvirt allows attackers to     cause a denial of service (memory consumption) via a     large QEMU reply.(CVE-2018-5748)

  - Systems with microprocessors utilizing speculative     execution and speculative execution of memory reads     before the addresses of all prior memory writes are     known may allow unauthorized disclosure of information     to an attacker with local user access via a     side-channel analysis, aka Speculative Store Bypass     (SSB), Variant 4.(CVE-2018-3639)

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