        "Description": "This update upgrades tomcat to version 9.0.45-alt1_1jpp11. \nSecurity Fix(es):\n\n * BDU:2021-03687: Уязвимость реализации неблокирующего метода ввода/вывода («nonblocking I/O») сервера приложений Apache Tomcat, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2021-30639: A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag associated with the Request object was not reset between requests. This meant that once a non-blocking I/O error occurred, all future requests handled by that request object would fail. Users were able to trigger non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a DoS. Applications that do not use non-blocking I/O are not exposed to this vulnerability. This issue affects Apache Tomcat 10.0.3 to 10.0.4; 9.0.44; 8.5.64.\n\n * #40087: не закрыты CVE-2020-13943, CVE-2020-17527, CVE-2021-24122, CVE-2021-25122, CVE-2021-25329",
