Denial Of Service (DoS)

golang is vulnerable to denial of service. The vulnerability exists due to a data overwrite when invoking functions from WASM modules, built using GOARCH=wasm GOOS=js, passing very large arguments...

FreeBSD : go -- misc/wasm, cmd/link: do not let command line arguments overwrite global data (4fce9635-28c0-11ec-9ba8-002324b2fba8)

The Go project reports : When invoking functions from WASM modules, built using GOARCH=wasm GOOS=js, passing very large arguments can cause portions of the module to be overwritten with data from the arguments. If using wasmexec.js to execute WASM modules, users will need to replace their copy...

GHSA-4873-36H9-WV49 Out-of-bounds read/write and invalid free with `externref`s and GC safepoints in Wasmtime

Impact There was an invalid free and out-of-bounds read and write bug when running Wasm that uses externrefs in Wasmtime. To trigger this bug, Wasmtime needs to be running Wasm that uses externrefs, the host creates non-null externrefs, Wasmtime performs a garbage collection GC, and there has to ...

GHSA-V4CP-H94R-M7XF Use after free passing `externref`s to Wasm in Wasmtime

Impact 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 Wasm instance at the same time, either by passing multiple externrefs as arguments from host code to a Wasm...

CVE-2021-32629

Cranelift’s x64 backend bug in 0.73 (and certain earlier builds when the new backend is explicitly selected) can sign-extend a loaded i32 value, potentially enabling sandbox escapes in Wasm modules and exposing memory up to 2 GiB before the heap. Wasmtime and Lucet using Cranelift may be exploita...

Exploit for Improper Input Validation in Google Chrome

PoC exploit for CVE-2020-16040, an out-of-bounds read vulnerability in the WebAssembly WASM module loader. The exploit targets the WASM module loader's handling of WebAssembly code, specifically the wasmcode array, which is used to load and execute WASM modules. The vulnerability allows an attack...
