The default_validator.cc implementation used to implement the default certificate validation routines has a \"type confusion\" bug when processing subjectAltNames. This processing allows, for example, an rfc822Name or uniformResourceIndicator to be authenticated as a domain name. This confusion allows for the bypassing of nameConstraints, as processed by the underlying OpenSSL/BoringSSL implementation, exposing the possibility of impersonation of arbitrary servers. As a result Envoy will trust upstream certificates that should not be trusted.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2022-21656","url":"https://www.suse.com/security/cve/CVE-2022-21656"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1196430 for CVE-2022-21656","url":"https://bugzilla.suse.com/1196430"}],"title":"SUSE CVE CVE-2022-21656","tracking":{"current_release_date":"2025-02-16T07:45:07Z","generator":{"date":"2023-02-15T03:29:11Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2022-21656","initial_release_date":"2023-02-15T03:29:11Z","revision_history":[{"date":"2023-02-15T03:29:11Z","number":"2","summary":"Current version"},{"date":"2025-01-01T03:17:36Z","number":"3","summary":"Current version"},{"date":"2025-02-15T03:57:24Z","number":"4","summary":"Current version"},{"date":"2025-02-16T07:45:07Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
