AlmaLinux 8 : sudo (ALSA-2023:0284)
high Nessus Plugin ID 170551
Synopsis
The remote AlmaLinux host is missing a security update.Description
The remote AlmaLinux 8 host has a package installed that is affected by a vulnerability as referenced in the ALSA-2023:0284 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.
