If the `Error::type_id` method is overridden then any type can be safely cast to any other type, causing memory safety vulnerabilities in safe code (e.g., out-of-bounds write or read). Code that does not manually implement Error::type_id is unaffected.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-125","CWE-787"],"references":["http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00076.html","http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00006.html","http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00031.html","https://blog.rust-lang.org/2019/05/13/Security-advisory.html","https://groups.google.com/forum/#%21topic/rustlang-security-announcements/aZabeCMUv70"],"products":["fedoraproject:fedora","opensuse:leap","rust-lang:rust"],"source":"nvd","synced_at":"2026-10-19T20:56:19.218283075+00:00"},"epss":{"cve":"CVE-2019-12083","score":0.02216,"percentile":0.82637,"date":"2026-10-31"},"kev":null,"osv":[],"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).
