        "Description": "This update upgrades docker-engine to version 20.10.3-alt1. \nSecurity Fix(es):\n\n * BDU:2021-01892: Уязвимость демона dockerd средства автоматизации развёртывания и управления приложениями в средах с поддержкой контейнеризации Docker, связанная с ошибкой механизма контроля расходуемых ресурсов, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2021-01893: Уязвимость опции --userns-remap средства автоматизации развёртывания и управления приложениями в средах с поддержкой контейнеризации Docker, связанная с некорректным ограничением имени пути к каталогу, позволяющая нарушителю оказать воздействие на целостность данных\n\n * CVE-2021-21284: In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using \"--userns-remap\", if the root user in the remapped namespace has access to the host filesystem they can modify files under \"/var/lib/docker/\u003cremapping\u003e\" that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user.\n\n * CVE-2021-21285: In Docker before versions 9.03.15, 20.10.3 there is a vulnerability in which pulling an intentionally malformed Docker image manifest crashes the dockerd daemon. Versions 20.10.3 and 19.03.15 contain patches that prevent the daemon from crashing.",
