{"id":"GHSA-p6rv-2qpm-fwvg","summary":"kill: 'kill -1' parsed as PID -1, sending SIGTERM to all processes (system crash / DoS)","details":"`kill -1` is incorrectly parsed as a positional `pid = -1`; combined with the default SIGTERM this calls `kill(-1, SIGTERM)`, signaling nearly every process the caller can see. GNU `kill` recognizes `-1`/`-9` as signals and reports \"not enough arguments\".\n\n```\n$ kill -1        # uutils: kill(-1, SIGTERM) -\u003e mass termination / crash\n$ kill -1        # GNU: kill: not enough arguments\n```\n\n**Impact:** a user running `kill -1` mass-terminates processes, potentially crashing the system. Recommendation: parse `-N` as a signal number, and error with \"not enough arguments\" when no PID is given.\n\n**Remediation:** Acknowledged by Canonical; fixed in commit cae94028.\n\n---\n_Reported by Zellic in the *uutils coreutils Program Security Assessment* (prepared for Canonical, Jan 20 2026), audited commit `3a07ffc5a9bd4c283e75afa548ba1f1957bad242`.
