uutils coreutils has an Improper Input Validation issue

Published: 4/22/2026Modified: 5/5/2026
Also known as:GHSA-gpcg-h6x2-c26p

Description

An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal (SIGTERM) to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massive process termination. This differs from GNU coreutils, which correctly recognizes -1 as a signal number in this context and would instead report a missing PID argument.
