  - Wasmtime is a standalone runtime for WebAssembly. Prior to version 2.0.2, there is a bug in Wasmtime's
    implementation of its pooling instance allocator when the allocator is configured to give WebAssembly
    instances a maximum of zero pages of memory. In this configuration, the virtual memory mapping for
    WebAssembly memories did not meet the compiler-required configuration requirements for safely executing
    WebAssembly modules. Wasmtime's default settings require virtual memory page faults to indicate that wasm
    reads/writes are out-of-bounds, but the pooling allocator's configuration would not create an appropriate
    virtual memory mapping for this meaning out of bounds reads/writes can successfully read/write memory
    unrelated to the wasm sandbox within range of the base address of the memory mapping created by the
    pooling allocator. This bug is not applicable with the default settings of the `wasmtime` crate. This bug
    can only be triggered by setting `InstanceLimits::memory_pages` to zero. This is expected to be a very
    rare configuration since this means that wasm modules cannot allocate any pages of linear memory. All wasm
    modules produced by all current toolchains are highly likely to use linear memory, so it's expected to be
    unlikely that this configuration is set to zero by any production embedding of Wasmtime. This bug has been
    patched and users should upgrade to Wasmtime 2.0.2. This bug can be worked around by increasing the
    `memory_pages` allotment when configuring the pooling allocator to a value greater than zero. If an
    embedding wishes to still prevent memory from actually being used then the `Store::limiter` method can be
    used to dynamically disallow growth of memory beyond 0 bytes large. Note that the default `memory_pages`
    value is greater than zero. (CVE-2022-39392)

Note that Nessus relies on the presence of the package as reported by the vendor.");
