Researchers have identified two significant vulnerabilities in Wasmtime, a WebAssembly runtime used in various software applications. These flaws could enable attackers to bypass the security measures that isolate WebAssembly modules, allowing potentially harmful code to execute outside its intended sandbox. The vulnerabilities specifically affect certain builds of Wasmtime, with one flaw limited to ARM64 systems. To exploit these issues, an attacker would first need access to a vulnerable Wasmtime version to compile their malicious module. The developers have released fixed versions to address these vulnerabilities, underscoring the need for users to update their systems promptly to prevent potential exploitation.
