Description

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.

Solution(s)

  • suse-upgrade-sudo
  • suse-upgrade-sudo-devel
  • suse-upgrade-sudo-test
