Bytecodealliance Cranelift-Codegen vulnerabilities

CVE-2023-26489 [CRITICAL] CWE-125 CVE-2023-26489: wasmtime is a fast and secure runtime for WebAssembly. In affected versions wasmtime's code generato wasmtime is a fast and secure runtime for WebAssembly. In affected versions wasmtime's code generator, Cranelift, has a bug on x86_64 targets where address-mode computation mistakenly would calculate a 35-bit effective address instead of WebAssembly's defined 33-bit effective address. This bug means that, with default codegen settings, a wasm-cont

CVE-2023-27477 [MEDIUM] CWE-193 CVE-2023-27477: wasmtime is a fast and secure runtime for WebAssembly. Wasmtime's code generation backend, Cranelift wasmtime is a fast and secure runtime for WebAssembly. Wasmtime's code generation backend, Cranelift, has a bug on x86_64 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 indices are greater than 16. There is an off-by-one error

CVE-2022-31169 [HIGH] CWE-682 CVE-2022-31169: Wasmtime is a standalone runtime for WebAssembly. There is a bug in Wasmtime's code generator, Crane Wasmtime is a standalone runtime for WebAssembly. There is a bug in Wasmtime's code generator, Cranelift, for AArch64 targets where constant divisors can result in incorrect division results at runtime. This affects Wasmtime prior to version 0.38.2 and Cranelift prior to 0.85.2. This issue only affects the AArch64 platform. Other platforms are not aff

CVE-2022-31146 [HIGH] CWE-416 CVE-2022-31146: Wasmtime is a standalone runtime for WebAssembly. There is a bug in the Wasmtime's code generator, C Wasmtime is a standalone runtime for WebAssembly. There is a bug in the Wasmtime's code generator, Cranelift, where functions using reference types may be incorrectly missing metadata required for runtime garbage collection. This means that if a GC happens at runtime then the GC pass will mistakenly think these functions do not have live references to

CVE-2022-23636 [MEDIUM] Cranelift vulnerable to miscompilation of constant values in division on AArch64 Cranelift vulnerable to miscompilation of constant values in division on AArch64 ### Impact There was a bug in Wasmtime's code generator, Cranelift, for AArch64 targets where constant divisors could result in incorrect division results at runtime. The translation rules for constants did not take into account whether sign- or zero-extension should happen, which resulted in an incorrect value

CVE-2022-31104 [MEDIUM] CWE-682 CVE-2022-31104: Wasmtime is a standalone runtime for WebAssembly. In affected versions wasmtime's implementation of Wasmtime is a standalone runtime for WebAssembly. In affected versions wasmtime's implementation of the SIMD proposal for WebAssembly on x86_64 contained two distinct bugs in the instruction lowerings implemented in Cranelift. The aarch64 implementation of the simd proposal is not affected. The bugs were presented in the `i8x16.swizzle` and `select`

CVE-2021-32629 [HIGH] CWE-788 CVE-2021-32629: Cranelift is an open-source code generator maintained by Bytecode Alliance. It translates a target-i Cranelift is an open-source code generator maintained by Bytecode Alliance. It translates a target-independent intermediate representation into executable machine code. There is a bug in 0.73 of the Cranelift x64 backend that can create a scenario that could result in a potential sandbox escape in a Wasm program. This bug was introduced in the new bac
