Description

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-gw5h-h6hj-f56g. This link is maintained to preserve external references.

Original Description

Impact

Expired PAM accounts and accounts with expired passwords are continued to be seen as valid. Installations use PAM as authentication sources are affected.

Patches

Expired PAM accounts and accounts with expired passwords are no longer being seen as valid. Users should upgrade to 0.12.5 or the latest 0.13.0+dev.

Workarounds

In addition to marking PAM accounts as expired, also disable/lock them. Running usermod -L <username> will add an exclamation mark to the password hash and would result in wrong passwords responses when trying to login.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
