How to Fix CVE-2022-36124

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

apache-avro fixed: 0.14.0 
Upgrade apache-avro to 0.14.0
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 apache-avro

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-36124, inspect your project dependencies for Apache avro:

inspect dependencies for apache-avro

Analyze the terminal output to locate any version of Apache avro in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.14.0), 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-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Apache avro, 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

It is possible for a Reader to consume memory beyond the allowed constraints and thus lead to out of memory on the system. This issue affects Rust applications using Apache Avro Rust SDK prior to 0.14.0 (previously known as avro-rs). Users should update to apache-avro version 0.14.0 which addresses this issue.
