Synopsis

The remote Red Hat 7 host is affected by multiple vulnerabilities that will not be patched.

Description

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.

- systemd: Mishandled symlinks in systemd-tmpfiles allows local users to obtain ownership of arbitrary files (CVE-2018-6954)

- systemd, when updating file permissions, allows local users to change the permissions and SELinux security contexts for arbitrary files via a symlink attack on unspecified files. (CVE-2013-4392)

- The machinectl command in oci-register-machine allows local users to list running containers and possibly obtain sensitive information by running that command. (CVE-2016-6349)

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