CVE-2026-5188
Integer underflow in X.509 SAN parsing in wolfSSL
Résumé
Integer underflow in X.509 SAN parsing in wolfSSL
Description d'origine
La description telle que publiée par la source (souvent en anglais).
An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name (SAN) extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect handling of certificate data. The issue is limited to configurations using the original ASN.1 parsing implementation which is off by default.
