Slackware Linux 14.0 / 14.1 / 14.2 / 15.0 / current sudo Vulnerability (SSA:2023-018-01)

high Nessus Plugin ID 170153

Language:

Synopsis

The remote Slackware Linux host is missing a security update to sudo.

Description

The version of git installed on the remote host is prior to 2.30.7 / 2.35.6 / 2.39.1. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-018-01 advisory.

- 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 Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the affected sudo package.
