How to Fix CVE-2016-10932

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

hyper fixed: 0.9.4 
Upgrade hyper to 0.9.4
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 hyper

How to Check if You Are Affected

To determine whether your application is affected by CVE-2016-10932, inspect your project dependencies for Hyper:

inspect dependencies for hyper

Analyze the terminal output to locate any version of Hyper in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.9.4), 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-347: Improper Verification of Cryptographic Signature, where the product does not verify, or incorrectly verifies, the cryptographic signature for data. In Hyper, 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

When used on Windows platforms, all versions of Hyper prior to 0.9.4 did not perform hostname verification when making HTTPS requests. This allows an attacker to perform MitM attacks by preventing any valid CA-issued certificate, even if there's a hostname mismatch. The problem was addressed by leveraging rust-openssl's built-in support for hostname verification.
