Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string `-----BEGIN RSA PUBLIC KEY-----` which is not accounted for. This enables symmetric/asymmetric key confusion attacks against users using the PKCS1 PEM encoded public keys, which would allow an attacker to craft JWTs from scratch.","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-2017-11424","url":"https://www.suse.com/security/cve/CVE-2017-11424"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1054106 for CVE-2017-11424","url":"https://bugzilla.suse.com/1054106"}],"title":"SUSE CVE CVE-2017-11424","tracking":{"current_release_date":"2025-02-18T07:40:19Z","generator":{"date":"2023-02-15T04:42:56Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2017-11424","initial_release_date":"2023-02-15T04:42:56Z","revision_history":[{"date":"2023-02-15T04:42:56Z","number":"2","summary":"Current version"},{"date":"2023-12-08T04:22:30Z","number":"3","summary":"Current version"},{"date":"2025-01-01T08:42:55Z","number":"4","summary":"Current version"},{"date":"2025-02-18T07:40:19Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
