CVE-2026-35350 Details
Description
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.
A vulnerability exists in the cp utility of uutils coreutils, where it improperly manages setuid and setgid bits when ownership preservation fails. When the -p (preserve) flag is used, cp can retain original mode bits, including privileged bits, even if the chown operation fails. This behavior can lead to the creation of user-owned files with elevated privileges, allowing the execution of unauthorized actions or access to restricted resources, in violation of local security policies. This issue contrasts with GNU cp, which correctly removes these bits when ownership cannot be preserved.
Users can update to the latest version of uutils coreutils, where this issue has been addressed.
