Descripción:	Summary: The remote host is missing an update for the Huawei EulerOS 'sudo' package(s) announced via the EulerOS-SA-2021-1257 advisory. Vulnerability Insight: 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.(CVE-2021-23239) Sudo before 1.9.5p2 has a Heap-based Buffer Overflow, allowing privilege escalation to root via 'sudoedit -s' and a command-line argument that ends with a single backslash character.(CVE-2021-3156) 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.(CVE-2021-23240) Affected Software/OS: 'sudo' package(s) on Huawei EulerOS V2.0SP9.
