How to Fix CVE-2025-1057

To remediate this vulnerability, upgrade all affected Keylime dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

keylime fixed: 7.12.1 
pip install keylime>=7.12.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show keylime

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2025-1057, inspect your installed packages using pip:

pip show keylime

Analyze the terminal output to locate any version of Keylime in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.12.1), your application is affected.

Note: The pip show keylime command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1287: Improper Validation of Specified Type of Input, where the product receives input that is expected to be of a certain type, but it does not validate or incorrectly validates that the input is actually of the expected type. In Keylime, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The Keylime `registrar` implemented more strict type checking on version 7.12.0. As a result, when updated to version 7.12.0, the `registrar` will not accept the format of the data previously stored in the database by versions >= 7.8.0, raising an exception. This makes the Keylime `registrar` vulnerable to a Denial-of-Service attack in an update scenario, as an attacker could populate the `registrar` database by creating multiple valid agent registrations with different UUIDs while the version is still < 7.12.0. Then, when the Keylime `registrar` is updated to the 7.12.0 version, any query to the database matching any of the entries populated by the attacker will result in failure. ### Patches Users should upgrade to versions >= 7.12.1 ### Workarounds - Remove the registrar database and re-register all agents ### Credit Reported by: Anderson Toshiyuki Sasaki/@ansasaki Patched by: Anderson Toshiyuki Sasaki/@ansasaki
