EulerOS 2.0 SP9 : sudo (EulerOS-SA-2023-1459)

high Nessus Plugin ID 172303

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - In Sudo before 1.9.12p2, the sudoedit (aka -e) feature mishandles extra arguments passed in the user- provided environment variables (SUDO_EDITOR, VISUAL, and EDITOR), allowing a local attacker to append arbitrary entries to the list of files to process. This can lead to privilege escalation. Affected versions are 1.8.0 through 1.9.12.p1. The problem exists because a user-specified editor may contain a '--' argument that defeats a protection mechanism, e.g., an EDITOR='vim -- /path/to/extra/file' value.
 (CVE-2023-22809)

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.
