"Description": "This update upgrades libnghttp2 to version 1.41.0-alt1. \nSecurity Fix(es):\n\n * BDU:2020-04461: Уязвимость библиотеки nghttp2, связанная с ошибками при использовании выделенной памяти при обработке пакетов HTTP/2 SETTINGS, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2020-11080: In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., \u003e 32), then drop the connection.\n\n * #38626: Собрать версию v1.41.0, устраняющую CVE-2020-11080",
