Package : cloud-init
Version : 0.7.6~bzr976-2+deb8u1
CVE ID : CVE-2020-8631 CVE-2020-8632
Debian Bug : 951362 951363

CVE-2020-8631

In cloud-init, 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-2020-8632

In cloud-init, 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.

For Debian 8 "Jessie", these problems have been fixed in version
0.7.6~bzr976-2+deb8u1.

We recommend that you upgrade your cloud-init packages.
