Language:

Description

The remote host is affected by the vulnerability described in GLSA-202305-12 (sudo: Root Privilege Escalation)

- 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 this issue but has instead relied only on the application's self-reported version number.

Solution

All sudo users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose >=app-admin/sudo-1.9.12_p2
