How to Fix CVE-2020-35916

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

image fixed: 0.23.12 
Upgrade image to 0.23.12
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 image

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-35916, inspect your project dependencies for Image:

inspect dependencies for image

Analyze the terminal output to locate any version of Image in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.23.12), 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 Image, 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

A mutable reference to a struct was constructed by dereferencing a pointer obtained from slice::as_ptr. Instead, slice::as_mut_ptr should have been called on the mutable slice argument. The former performs an implicit reborrow as an immutable shared reference which does not allow writing through the derived pointer.
