How to Fix CVE-2017-18588

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

security-framework fixed: 0.1.12 
Upgrade security-framework to 0.1.12
Verify Direct and Transitive Dependencies

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

inspect dependencies for security-framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-18588, inspect your project dependencies for Security framework:

inspect dependencies for security-framework

Analyze the terminal output to locate any version of Security framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.1.12), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Security framework, 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

If custom root certificates were registered with a ClientBuilder, the hostname of the target server would not be validated against its presented leaf certificate. This issue was fixed by properly configuring the trust evaluation logic to perform that check.
