In a typical deployment of rust-phonenumber, this may get triggered by feeding a maliciously crafted phonenumber, e.g. over the network, specifically strings of the form `+dwPAA;phone-context=AA`, where the "number" part potentially parses as a number larger than 2^56. This vulnerability is fixed in 0.3.6.
