Rocky Linux 9 : sudo (RLSA-2023:0282)

high Nessus Plugin ID 184903

Synopsis

The remote Rocky Linux host is missing a security update.

Description

The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2023:0282 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 this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
