How to Fix CVE-2021-28028

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

toodee fixed: 0.3.0 
Upgrade toodee to 0.3.0
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 toodee

How to Check if You Are Affected

To determine whether your application is affected by CVE-2021-28028, inspect your project dependencies for Toodee:

inspect dependencies for toodee

Analyze the terminal output to locate any version of Toodee in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.0), 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-415: Double Free, where the product calls free() twice on the same memory address. In Toodee, 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 inserting rows from an iterator at a particular index, toodee would shift items over, duplicating their ownership. The space reserved for the new elements was based on the len() returned by the ExactSizeIterator. This could result in elements in the array being freed twice if the iterator panics. Uninitialized or previously freed elements could also be exposed if the len() didn't match the number of elements. These issues were fixed in commit `ced70c17` by temporarily setting the length of the array smaller while processing it and adding assertions on the number of elements returned by the iterator.
