EulerOS 2.0 SP3 : cloud-init (EulerOS-SA-2020-1373)

medium Nessus Plugin ID 135502

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the cloud-init package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

 - 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.

Solution

Update the affected cloud-init packages.
