MEDIUM6.6EPSS 0.01%uutils coreutils doesn't properly handle setuid and setgid bits when ownership preservation fails
發布日:2026/4/22修改日:2026/6/2
描述
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.
