Ubuntu 26.04 LTS : sudo-rs vulnerability (USN-8708-1)

info Nessus Plugin ID 365447

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 26.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-8708-1 advisory.

It was discovered that sudo-rs incorrectly handled time-of-check vs time- of-use conditions in sudoedit. A local attacker with permission to edit specific files using sudoedit could use this issue to place files in arbitrary directories, and possibly escalate their privileges. This issue only affected systems configured to grant fine-grained sudoedit file editing permissions, which is not the default configuration.

Tenable has extracted the preceding description block directly from the Ubuntu 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 sudo-rs package.
