How to Fix CVE-2020-25575

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

failure fixed: Latest secure release 
Upgrade failure 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 failure

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-25575, inspect your project dependencies for Failure:

inspect dependencies for failure

Analyze the terminal output to locate any version of Failure 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-843: Access of Resource Using Incompatible Type ('Type Confusion'), where the product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type. In Failure, 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 failure crate through 0.1.5 for Rust. It may introduce "compatibility hazards" in some applications, and has a type confusion flaw when downcasting. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: This may overlap CVE-2019-25010.
