uutils coreutils doesn't properly handle setuid and setgid bits when ownership preservation fails

Publisher and source text is retained separately from QFinch interpretation.

QFinch assessment

The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining original privileged bits, creating unexpected privileged executables that violate local security policies. This differs from GNU cp, which clears these bits when ownership cannot be preserved.
