The SHA-2 digest support in the sudoers plugin in sudo after 1.8.7 allows local users with write permissions to parts of the called command to replace them before it is executed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - sudo: Unauthorized privilege escalation in sudoedit (CVE-2015-5602)

  - sudo: by using ! character in the shadow file instead of a password hash can access to a run as all sudoer     account (CVE-2019-19234)

  - The SHA-2 digest support in the sudoers plugin in sudo after 1.8.7 allows local users with write     permissions to parts of the called command to replace them before it is executed. (CVE-2015-8239)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

- update to 1.8.17p1

  - installs the /var/db/sudo/lectured directory

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
