How to Fix CVE-2021-32823

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

bindata fixed: 2.4.10 
Upgrade bindata to 2.4.10
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 bindata

How to Check if You Are Affected

To determine whether your application is affected by CVE-2021-32823, inspect your project dependencies for Bindata:

inspect dependencies for bindata

Analyze the terminal output to locate any version of Bindata in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.10), 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Bindata, 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

In the bindata RubyGem before version 2.4.10 there is a potential denial-of-service vulnerability. In affected versions it is very slow for certain classes in BinData to be created. For example `BinData::Bit100000`, `BinData::Bit100001`, `BinData::Bit100002`, `BinData::Bit<N>`. In combination with `<user_input>.constantize` there is a potential for a CPU-based DoS. In version 2.4.10, bindata improved the creation time of Bits and Integers.
