[tor-relays] CVE-2015-7547 Tor network stats

[nusenu]

Hi,

if we assume for simplicity that every relay running Linux that has not
rebooted since 2016-02-16 is vulnerable to CVE-2015-7547, than these are
the current stats (optimistic, because we assume that everyone that
rebooted did also update).

Vulnerable relays:

+------------+------------------+-----------------+
| cwfraction | guardprobability | exitprobability |
+------------+------------------+-----------------+
|      0.586 |            0.639 |           0.518 |
+------------+------------------+-----------------+
(1=100%)

Apply patches and reboot.
