Debian dla-3714 : keystone - security update

high Nessus Plugin ID 189282

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3714 advisory.

- A flaw was found in openstack-keystone. Only the first 72 characters of an application secret are verified allowing attackers bypass some password complexity which administrators may be counting on. The highest threat from this vulnerability is to data confidentiality and integrity. (CVE-2021-3563)

- OpenStack Keystone 10.x through 16.x before 16.0.2, 17.x before 17.0.1, 18.x before 18.0.1, and 19.x before 19.0.1 allows information disclosure during account locking (related to PCI DSS features). By guessing the name of an account and failing to authenticate multiple times, any unauthenticated actor could both confirm the account exists and obtain that account's corresponding UUID, which might be leveraged for other unrelated attacks. All deployments enabling security_compliance.lockout_failure_attempts are affected. (CVE-2021-38155)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the keystone packages.
