脆弱性タイトル
uutils coreutils install Arbitrary File Overwrite via Symlink TOCTOU Race
ソース: NVD (National Vulnerability Database)
脆弱性説明
The install utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition during file installation. The implementation unlinks an existing destination file and then recreates it using a path-based operation without the O_EXCL flag. A local attacker can exploit the window between the unlink and the subsequent creation to swap the path with a symbolic link, allowing them to redirect privileged writes to overwrite arbitrary system files.
