CVE-2024-39697 — Vulnerability in phonenumber — CVE Details

CRITICAL

panic on parsing crafted phonenumber inputs

Published July 9, 2024Updated September 10, 2026Source: osv

Summary

### Impact The phonenumber parsing code may panic due to a reachable `assert!` guard on the phonenumber string. 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. Since f69abee1/0.3.4/#52. 0.2.x series is not affected. ### Patches Upgrade to 0.3.6 or higher. ### Workarounds n/a ### References Whereas https://github.com/whisperfish/rust-phonenumber/issues/69 did not provide an example code path, property testing found a few: `+dwPAA;phone-context=AA`.
