kill: 'kill -1' parsed as PID -1, sending SIGTERM to all processes (system crash / DoS)
CVE-2026-35369 · GHSA-p6rv-2qpm-fwvg
- Affected
- crates.io uu_kill < 0.6.0
- Fixed in
- 0.6.0· Vendor fix available
- Issue
- 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". 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. Remediation: Acknowledged by Canonical; fixed in commit cae94028. --- Reported by Zellic in the uutils coreutils Program Security Assessment (prepared for Canonical, Jan 20 2026), audited commit 3a07ffc5a9bd4c283e75afa548ba1f1957bad242. Finding 3.70. Credit: Zellic.
Recommended action: Upgrade to 0.6.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
