Wasmtime is a runtime for WebAssembly. In versions from 38.0.0 to before 38.0.3, the implementation of component-model related host-to-wasm trampolines in Wasmtime contained a bug where it's possible to carefully craft a component, which when called in a specific way, would crash the host with a segfault or assert failure. Wasmtime 38.0.3 has been released and is patched to fix this issue. There are no workarounds.
A Denial of Service vulnerability has been identified in the Wasmtime WebAssembly runtime, affecting versions 38.0.0 through 38.0.2. An attacker can exploit this flaw by providing a carefully crafted WebAssembly component and invoking it in a specific manner. This malicious action causes the host process to crash, leading to a complete disruption of service for applications utilizing the vulnerable runtime.
