How to Fix CVE-2020-36216

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

eventio fixed: 0.5.1 
Upgrade eventio to 0.5.1
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 eventio

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-36216, inspect your project dependencies for Eventio:

inspect dependencies for eventio

Analyze the terminal output to locate any version of Eventio in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.1), 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-662: Improper Synchronization, where the product utilizes multiple threads, processes, components, or systems to allow temporary access to a shared resource that can only be exclusive to one process at a time, but it does not properly synchronize these actions, which might cause simultaneous accesses of this resource by multiple threads or processes. In Eventio, 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

Input<R> implements Send without requiring R: Send. Affected versions of this crate allows users to send non-Send types to other threads, which can lead to undefined behavior such as data race and memory corruption. The flaw was corrected in version 0.5.1 by adding R: Send bound to the Send impl of Input<R>.
