EUVD-2019-0020Published

An issue was discovered in the arrayfire crate before 3.6.0 for Rust. Addition of the repr() attribute to an enum is mishandled, leading to memory corruption.

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
