| शीर्षक | wbond certvalidator 0.11.1 Denial of Service |
|---|
| विवरण | certvalidator (wbond) up to 0.11.1 is vulnerable to a denial-of-service via exponential certificate path-building (CWE-400). When processing a certificate chain containing multiple duplicate self-signed intermediate certificates with the same subject, the path-builder explores a factorial number of combinations. At N=9 duplicate intermediates CPU time exceeds 12 seconds. An attacker controlling a certificate chain presented to any application using certvalidator for TLS or X.509 validation can trigger sustained CPU exhaustion. Sibling of pyca/cryptography GHSA-jwv3-5hgf-82ww. CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). |
