Wasmtime is a runtime for WebAssembly. Starting in version 29.0.0 and prior to version 36.0.5, 40.0.3, and 41.0.1, on x86-64 platforms with AVX, Wasmtime's compilation of the f64.copysign WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are...

Wasmtime segfault or unused out-of-sandbox load with f64.copysign operator on x86-64

On x86-64 platforms with AVX Wasmtime's compilation of the f64.copysign WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can result in a uncaught segfault due to loading from unmapped guard pages. With guard pages disabled...

WasmTime buffer error vulnerability

Wasmtime is a lightweight WebAssembly runtime open source by the Bytecode Alliance. Versions of Wastime prior to 29.0.0, 36.0.5, 40.0.3, and 41.0.1 contained a buffer error vulnerability. This vulnerability arises due to Cranelift’s compilation of f64.copysign WebAssembly instructions on x86-64...

CVE-2022-31146

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...

Linux Distros Unpatched Vulnerability : CVE-2022-31169

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

CVE-2023-26489

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 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-2022-31104

Wasmtime is a standalone runtime for WebAssembly. In affected versions wasmtime's implementation of the SIMD proposal for WebAssembly on x8664 contained two distinct bugs in the instruction lowerings implemented in Cranelift. The aarch64 implementation of the simd proposal is not affected. The bu...

CVE-2021-32629

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 i...

CVE-2022-24791

Wasmtime is a standalone JIT-style runtime for WebAssembly, using Cranelift. There is a use after free vulnerability in Wasmtime when both running Wasm that uses externrefs and enabling epoch interruption in Wasmtime. If you are not explicitly enabling epoch interruption it is disabled by default...

CVE-2023-41880

Wasmtime is a standalone runtime for WebAssembly. Wasmtime versions from 10.0.0 to versions 10.02, 11.0.2, and 12.0.1 contain a miscompilation of the WebAssembly i64x2.shrs instruction on x8664 platforms when the shift amount is a constant value that is larger than 32. Only x8664 is affected so a...

Miscompilation of wasm `i64x2.shr_s` instruction with constant input on x86_64

Impact Wasmtime versions from 10.0.0 to 12.0.1 contain a miscompilation of the WebAssembly i64x2.shrs instruction on x8664 platforms when the shift amount is a constant value that is larger than 32. Only x8664 is affected so all other targets are not affected by this. The miscompilation results i...

The vulnerability of the Cranelift compiler (previously Cretonne) for WebAssembly applications, Wasmtime, arises from the execution of operations beyond the buffer boundaries in memory. This vulnerability allows an attacker to execute arbitrary code or cause a service failure.

The vulnerability of the Cranelift compiler previously Cretonne for WebAssembly applications relates to the execution environment. This vulnerability stems from the operation of pushing an instruction out of the buffer into memory when determining linear memory addressing rules. Exploiting this...
