Title: kill incorrectly parses negative PIDs Status in procps package in Ubuntu: Fix Released Status in procps source package in Xenial: Fix Committed Bug description: [Impact] When kill is called with a negative argument, incorrect parsing can lead it to call sys_kill(-1), thus sending a signal to all permitted processes on the system. A couple of users have hit this while deploying Hadoop, which seems to tickle this - basically killing everything on the system. [Test Case] Though I don't know what Hadoop is calling, here's a couple of ways to trigger this: One possibility is if kill were called w/ a numeric signal that happened to start with a '1' and while omitting the required <pid> argument: kill -12 Another would be to specify a numeric signal (that again happened to start with a 1) multiple times: kill -13 -13 12345 [Regression Risk] This is a backport from upstream that is already available in 16.10, with no known regressions.
