How to Fix CVE-2020-36207

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

aovec fixed: Latest secure release 
Upgrade aovec to Latest secure release
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 aovec

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-36207, inspect your project dependencies for Aovec:

inspect dependencies for aovec

Analyze the terminal output to locate any version of Aovec in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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 Aovec, 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

An issue was discovered in the aovec crate through 2020-12-10 for Rust. Because Aovec<T> does not have bounds on its Send trait or Sync trait, a data race and memory corruption can occur.
