From 30.0.0 to 36.0.8, 43.0.2, and 44.0.1, Wasmtime&#39;s allocation logic for a WebAssembly table contained checked arithmetic which panicked on overflow. This overflow is possible to trigger, and thus panic, when a table with an extremely large size is allocated. This is possible with the WebAssembly memory64 proposal where tables can have sizes in the 64-bit range as opposed to the previous 32-bit range which would not overflow. The panic happens when attempting to create a very large table, such as when instantiating a WebAssembly module or component. This vulnerability is fixed in 36.0.8, 43.0.2, and 44.0.1.</p> <p><strong>Affected:</strong> bytecodealliance wasmtime, Red Hat Hardened Images, Red Hat Enterprise Linux 10</p> <p>Wasmtime is a runtime for WebAssembly.
