  Minor correction, but that bug was never in any "official" coreutils release. The bug was in a multi-byte character patch that many distributions use (and still use). There have been other CVEs in that patch [1]. But the worst you can do is crash 'sort' with that. Note that uutils also has crashes. Here is one due to unbounded recursion: $ ./target/release/coreutils mkdir -p `python3 -c 'print("./" + "a/" * 32768)'` Segmentation fault (core dumped) Not saying that both issues don't deserve fixing. But I wouldn't really panic over either of them. [1] https://lwn.net/Articles/535735/ https://lwn.net/Articles/535735/
