EulerOS Virtualization 3.0.2.2 : sudo (EulerOS-SA-2023-1296)

high Nessus Plugin ID 170826

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the sudo package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected sudo packages.
