Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

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 :

- A double free memory issue was found to occur in the libvirt API responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver.
Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-25637)

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.

Solution

Update the affected libvirt package.
