Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35345[0]:
| A vulnerability in the tail utility of uutils coreutils allows for
| the exfiltration of sensitive file contents when using the
| --follow=name option. Unlike GNU tail, the uutils implementation
| continues to monitor a path after it has been replaced by a symbolic
| link, subsequently outputting the contents of the link's target. In
| environments where a privileged user (e.g., root) monitors a log
| directory, a local attacker with write access to that directory can
| replace a log file with a symlink to a sensitive system file (such
| as /etc/shadow), causing tail to disclose the contents of the
| sensitive file.
