Опубликовано: 10 апр. 2026
Источник: ubuntu
Приоритет: medium
EPSS Низкий
CVSS3: 5.9

Описание

wolfSSL's wc_PKCS7_DecodeAuthEnvelopedData() does not properly sanitize the AES-GCM authentication tag length received and has no lower bounds check. A man-in-the-middle can therefore truncate the mac field from 16 bytes to 1 byte, reducing the tag check from 2⁻¹²⁸ to 2⁻⁸.
