How to Fix CVE-2018-20998

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

arrayfire fixed: 3.6.0 
Upgrade arrayfire to 3.6.0
arrayfire fixed: 3.6.0 
pip install arrayfire>=3.6.0
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 arrayfire

How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-20998, inspect your project dependencies for Arrayfire:

inspect dependencies for arrayfire

Analyze the terminal output to locate any version of Arrayfire in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.6.0), 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. In Arrayfire, 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

The attribute repr() added to enums to be compatible with C-FFI caused memory corruption on MSVC toolchain. arrayfire crates <= version 3.5.0 do not have this issue when used with Rust versions 1.27 or earlier. The issue only started to appear since Rust version 1.28. The issue seems to be interlinked with which version of Rust is being used. The issue was fixed in crate 3.6.0.
