CVE-2023-27477

wasmtime is a fast and secure runtime for WebAssembly. Wasmtime's code generation backend, Cranelift, has a bug on x8664 platforms for the WebAssembly i8x16.select instruction which will produce the wrong results when the same operand is provided to the instruction and some of the selected indice...

CVE-2023-26489: Out-of-bounds Read

wasmtime is a fast and secure runtime for WebAssembly. In affected versions wasmtime's code generator, Cranelift, has a bug on x8664 targets where address-mode computation mistakenly would calculate a 35-bit effective address instead of WebAssembly's defined 33-bit effective address. This bug mea...

CVE-2023-27477

Wasmtime Cranelift on x86_64 has a codegen bug for i8x16.select that can yield incorrect results when the same operand is used and some selected indices exceed 16. The off-by-one error in the mask calculation for pshufb may cause wrong results when lanes are taken from the second vector. This iss...
