CVE-2021-23240
Fixed in a distro release EPSS 1%
selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.
Products: sudo_project sudo, netapp hci_management_node, netapp solidfire, fedoraproject fedora
