"Description": "This update upgrades sudo to version 1.9.5p2-alt1. \nSecurity Fix(es):\n\n * BDU:2020-00856: Уязвимость учетной записи sudoer в файле Runas ALL программы системного администрирования Sudo, позволяющая нарушителю отключить аутентификацию пользователя по локальному паролю\n\n * BDU:2020-00857: Уязвимость учетной записи sudoer в файле Runas ALL программы системного администрирования Sudo, позволяющая нарушителю выдать себя за несуществующего пользователя\n\n * BDU:2021-00364: Уязвимость функции parse_args() программы системного администрирования Sudo, позволяющая нарушителю повысить свои привилегии до уровня root\n\n * BDU:2022-05782: Уязвимость команды sudoedit программы системного администрирования Sudo, позволяющая нарушителю получить доступ к конфиденциальным данным\n\n * CVE-2019-19232: In Sudo through 1.8.29, an attacker with access to a Runas ALL sudoer account can impersonate a nonexistent user by invoking sudo with a numeric uid that is not associated with any user. NOTE: The software maintainer believes that this is not a vulnerability because running a command via sudo as a user not present in the local password database is an intentional feature. Because this behavior surprised some users, sudo 1.8.30 introduced an option to enable/disable this behavior with the default being disabled. However, this does not change the fact that sudo was behaving as intended, and as documented, in earlier versions\n\n * CVE-2019-19234: In Sudo through 1.8.29, the fact that a user has been blocked (e.g., by using the ! character in the shadow file instead of a password hash) is not considered, allowing an attacker (who has access to a Runas ALL sudoer account) to impersonate any blocked user. NOTE: The software maintainer believes that this CVE is not valid. Disabling local password authentication for a user is not the same as disabling all access to that user--the user may still be able to login via other means (ssh key, kerberos, etc). Both the Linux shadow(5) and passwd(1) manuals are clear on this. Indeed it is a valid use case to have local accounts that are _only_ accessible via sudo and that cannot be logged into with a password. Sudo 1.8.30 added an optional setting to check the _shell_ of the target user (not the encrypted password!) against the contents of /etc/shells but that is not the same thing as preventing access to users with an invalid password hash\n\n * CVE-2021-23239: The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.\n\n * CVE-2021-23240: selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.\n\n * CVE-2021-3156: Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which allows privilege escalation to root via \"sudoedit -s\" and a command-line argument that ends with a single backslash character.\n\n * #39615: CVE-2021-3156",
