Prior to version 1.7.1, lc_x509_extract_name_segment() casts size_t vlen to uint8_t when storing the Common Name (CN) length. An attacker who crafts a certificate with CN = victim&#39;s CN + 256 bytes padding gets cn_size = (uint8_t)(256 + N) = N, where N is the victim&#39;s CN length. The first N bytes of the attacker&#39;s CN are the victim&#39;s identity. After parsing, the attacker&#39;s certificate has an identical CN to the victim&#39;s — enabling identity impersonation in PKCS#7 verification, certificate chain matching, and code signing. This issue has been patched in version 1.7.1.</p> <p><strong>Affected:</strong> smuellerDD leancrypto</p> <p>The leancrypto library is a cryptographic library that exclusively contains only PQC-resistant cryptographic algorithms.
