{"cve":"CVE-2023-42444","nvd":{"published":"2023-09-19T15:15:56.660","modified":"2026-06-17T06:23:50.550","status":"Modified","description":"phonenumber is a library for parsing, formatting and validating international phone numbers. Prior to versions `0.3.3+8.13.9` and `0.2.5+8.11.3`, the phonenumber parsing code may panic due to a panic-guarded out-of-bounds access on the phonenumber string. In a typical deployment of `rust-phonenumber`, this may get triggered by feeding a maliciously crafted phonenumber over the network, specifically the string `.;phone-context=`. Versions `0.3.3+8.13.9` and `0.2.5+8.11.3` contain a patch for this issue. There are no known workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-1284","CWE-248","CWE-392"],"references":["https://github.com/whisperfish/rust-phonenumber/commit/2dd44be94539c051b4dee55d1d9d349bd7bedde6","https://github.com/whisperfish/rust-phonenumber/commit/bea8e732b9cada617ede5cf51663dba183747f71","https://github.com/whisperfish/rust-phonenumber/security/advisories/GHSA-whhr-7f2w-qqj2","https://github.com/whisperfish/rust-phonenumber/commit/2dd44be94539c051b4dee55d1d9d349bd7bedde6","https://github.com/whisperfish/rust-phonenumber/commit/bea8e732b9cada617ede5cf51663dba183747f71"],"products":["whisperfish:phonenumber"],"source":"nvd","synced_at":"2026-10-19T21:39:24.235896374+00:00"},"epss":{"cve":"CVE-2023-42444","score":0.00867,"percentile":0.58728,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-whhr-7f2w-qqj2","url":"https://osv.dev/vulnerability/GHSA-whhr-7f2w-qqj2","summary":"phonenumber panics on parsing crafted RFC3966 inputs","modified":"2026-03-13T10:47:43.430911Z","packages":[{"ecosystem":"crates.io","name":"phonenumber","purl":"pkg:cargo/phonenumber","ranges":["<0.2.5"],"fixed":["0.2.5"]},{"ecosystem":"crates.io","name":"phonenumber","purl":"pkg:cargo/phonenumber","ranges":[">=0.3.0 <0.3.3"],"fixed":["0.3.3"]}]},{"id":"RUSTSEC-2023-0082","url":"https://osv.dev/vulnerability/RUSTSEC-2023-0082","summary":"phonenumber:  panic on parsing crafted RF3966 phonenumber inputs","modified":"2026-10-13T15:15:51.096651256Z","packages":[{"ecosystem":"crates.io","name":"phonenumber","purl":"pkg:cargo/phonenumber","ranges":[">=0.0.0-0 <0.2.5",">=0.3.0 <0.3.3"],"fixed":["0.2.5","0.3.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
