According to the version of the libvirt packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - 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)

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.

  - 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)

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2019:14097-1 advisory.

  - It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the     virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the     permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to     probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary     programs. (CVE-2019-10161)

  - 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)

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

This update for libvirt fixes the following issues :
