GHSA-8VRF-R662-2W2V cp: -R reads device nodes as streams, destroying device semantics

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...
