How to Fix CVE-2018-1000167

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

suricata-update fixed: 1.0.0b1 
pip install suricata-update>=1.0.0b1
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 suricata-update

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2018-1000167, inspect your installed packages using pip:

pip show suricata-update

Analyze the terminal output to locate any version of Suricata update in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0b1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Suricata update, 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

Suricata-Update uses the insecure `yaml.load()` function. Code will be executed if the yaml-file contains lines like: ```yaml hello: !!python/object/apply:os.system ['ls -l > /tmp/output'] ``` The vulnerable function can be triggered by "suricata-update list-sources". The locally stored index.yaml will be loaded in this function and the malicious code gets executed.
