Описание
Код, реализующий SSL/TLS-handshake, в OpenSSL, некорректно проверяет длину Kerberos-tickets при осуществлении процедуры handshake с использованием Kerberos-шифрования. Это позволяет злоумышленникам, действующим удаленно, вызвать отказ в обслуживании, изменяя параметры во время SSL/TLS-handshake.
Как исправить
Для устранения уязвимости необходимо установить последнюю версию продукта, соответствующую используемой платформе. Необходимую информацию можно получить по адресу:
