Vulnerability Title
Wasmtime panics when lifting `flags` component value
Vulnerability Description
Wasmtime is a runtime for WebAssembly. Prior to 24.0.7, 36.0.7, 42.0.2, and 43.0.1, Wasmtime contains a possible panic which can happen when a flags-typed component model value is lifted with the Val type. If bits are set outside of the set of flags the component model specifies that these bits should be ignored but Wasmtime will panic when this value is lifted. This panic only affects wasmtime's implementation of lifting into Val, not when using the flags! macro. This additionally only affects flags-typed values which are part of a WIT interface. This has the risk of being a guest-controlled panic within the host which Wasmtime considers a DoS vector. This vulnerability is fixed in 24.0.7, 36.0.7, 42.0.2, and 43.0.1.

wasmtime 安全漏洞
Vulnerability Description
wasmtime是Bytecode Alliance开源的一个轻量级WebAssembly运行时。 Wasmtime 24.0.7之前版本、36.0.7之前版本、42.0.2之前版本和43.0.1之前版本存在安全漏洞，该漏洞源于当使用Val类型提升标志类型组件模型值时，如果设置了组件模型指定范围之外的位，Wasmtime会在提升该值时发生恐慌，可能导致由访客控制的恐慌，构成拒绝服务向量。
