EulerOS Virtualization for ARM 64 3.0.2.0 : cloud-init (EulerOS-SA-2020-1519)
medium Nessus Plugin ID 136222
Synopsis
The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.Description
According to the versions of the cloud-init package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :- Cloud-init is a set of init scripts for cloud instances. Cloud instances need special scripts to run during initialization to retrieve and install ssh keys and to let the user run various scripts.Security Fix(es):cloud-init through 19.4 relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function.(CVE-2020-8631)A security feature bypass exists in Azure SSH Keypairs, due to a change in the provisioning logic for some Linux images that use cloud-init, aka 'Azure SSH Keypairs Security Feature Bypass Vulnerability'.(CVE-2019-0816)In cloud-init through 19.4, rand_user_password in cloudinit/config/cc_set_passwords.py has a small default pwlen value, which makes it easier for attackers to guess passwords.(CVE-2020-8632)
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.
