Vulnerability Title
uutils coreutils mv Silent Ownership Loss in Cross-Device Operations
Source: NVD (National Vulnerability Database)
Vulnerability Description
The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and migrations, causing files moved by a privileged user (e.g., root) to become root-owned unexpectedly, which can lead to information disclosure or restricted access for the intended owners.

Vulnerability Title
uutils coreutils 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
uutils coreutils是Uutils开源的一个跨平台核心命令行工具集。 uutils coreutils存在安全漏洞，该漏洞源于mv实用程序在不同文件系统边界移动时未能保留文件所有权，实用程序回退到复制和删除例程，使用调用者的UID/GID而非源的元数据创建目标文件，此缺陷破坏备份和迁移，导致特权用户移动的文件意外变为root所有，可能造成信息泄露或限制预期所有者的访问。
