Use CVE-2014-5508 for the integer overflow.

(As far as we could tell from your discussion, there is no way for an
attacker to specify a negative number directly. That situation would
require a separate CVE ID. In other words, the patch to timeq.c
apparently detects a condition that's possible only after an integer
overflow occurs.)
