From 16cde63e05519c770daa69345b8cf37fb31eaa2a Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Thu, 10 Dec 2015 08:59:34 +0100 Subject: jobs: Don't attempt to access job table for job %0 If job %0 is (mistakenly) specified, an out-of-bounds access to the jobtab occurs in function getjob() if num = 0: jp = jobtab + 0 - 1 Fix this by checking that the job number is larger than 0 before accessing the jobtab.
