The implementation enforces UTF-8 encoding and utilizes expect(), causing an immediate crash when encountering valid but non-UTF-8 paths. This diverges from GNU sort, which treats filenames as raw bytes. A local attacker can exploit this to crash the utility and disrupt automated pipelines."},{"lang":"es","value":"La utilidad “sort” en “uutils coreutils” es vulnerable a un pánico de proceso al usar la opción “--files0-from” con entradas que contienen nombres de archivo que no son UTF-8.
