FreeBSD : security/sudo-rs -- sudoedit could circumvent /etc/sudoers restrictions (c0acdbac-a524-11f1-8039-589cfc103809)

high Nessus Plugin ID 342212

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the c0acdbac-a524-11f1-8039-589cfc103809 advisory.

Trifecta Tech Foundation reports:
Users that are explicitly permitted to edit only specific files using sudoedit, are still able to place files in arbitrary directories.
This only affects systems where sudoedit is used to give very fine-grained edit permissions, which is not the default configuration. For users that have full sudoedit permission or no sudoedit permission at all, no escalation is enabled by this bug.
A user that is allowed to place files in an arbitrary directory can (by placing a file in /etc/sudoers.d) obviously fully escalate their privileges.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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.
