Уязвимость функции name_constraints_node_list_intersect() файла lib/x509/name_constraints.c:726-727 криптографической библиотеки GnuTLS, позволяющая нарушителю выполнить атаку MITM

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
