Alpine: multiple sudo packages: security update to 1.9.5-r0

high Tenable Self-Hosted Container Security Plugin ID 407288

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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)

 - 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)
