Versions before 2.0.2 of the crate 'enum-map' did not properly check the length of an enum when using enum_map! macro, trusting user-provided length. Fixed in version 2.0.2. When the LENGTH in the Enum trait does not match the array length in the EnumArray trait, this can result in the initialization of the enum map with uninitialized types, which in turn can allow an attacker to execute arbitrary code. This problem can only occur with a manual implementation of the Enum trait, it will never occur for enums that use #[derive(Enum)].
