According to the versions of the libvirt packages installed, the EulerOS 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 Load i1/4+ Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently 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 read privileged memory by conducting targeted cache side-channel attacks.(CVE-2018-3639)
qemu/qemu_monitor.c in libvirt allows attackers to cause a denial of service (memory consumption) via a large QEMU reply.(CVE-2018-5748)
An incomplete fix for CVE-2018-5748 that affects QEMU monitor leading to a resource exhaustion but now also triggered via QEMU guest agent.(CVE-2018-1064)
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.
