CVE-2021-39219

Wasmtime is an open source runtime for WebAssembly & WASI. Wasmtime before version 0.30.0 is affected by a type confusion vulnerability. As a Rust library the wasmtime crate clearly marks which functions are safe and which are unsafe, guaranteeing that if consumers never use unsafe then it should...

CVE-2021-39216

Wasmtime is an open source runtime for WebAssembly & WASI. In Wasmtime from version 0.19.0 and before version 0.30.0 there was a use-after-free bug when passing externrefs from the host to guest Wasm content. To trigger the bug, you have to explicitly pass multiple externrefs from the host to a...

CVE-2021-39216

Wasmtime (pre-0.30.0) contains a use-after-free when passing multiple externref values from host to guest Wasm, potentially allowing a GC to reclaim the first externref and then reuse it after control returns to Wasm. Affected versions are 0.19.0–0.29.0; upgrading to Wasmtime 0.30.0 fixes the iss...
