Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35377[0]:
| A logic error in the env utility of uutils coreutils causes a
| failure to correctly parse command-line arguments when utilizing the
| -S (split-string) option. In GNU env, backslashes within single
| quotes are treated literally (with the exceptions of \\ and \').
| However, the uutils implementation incorrectly attempts to validate
| these sequences, resulting in an "invalid sequence" error and an
| immediate process termination with an exit status of 125 when
| encountering valid but unrecognized sequences like \a or \x. This
| divergence from GNU behavior breaks compatibility for automated
| scripts and administrative workflows that rely on standard split-
| string semantics, leading to a local denial of service for those
| operations.
