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.

The Check Point Firewall-1 SMTP Security Server in Firewall-1 4.0 and 4.1 on Windows NT is vulnerable to a simple network-based attack which can increase the firewall's CPU utilization to 100%. Sending a stream of binary zeros (or other invalid SMTP commands) to the SMTP port on the firewall raises the target system's load to 100% while the load on the attacker's machine remains relatively low. According to Check Point Software this only disables mail relay while allowing other firewall operations to continue normally.
This can easily be reproduced from a Linux system using netcat with an input of /dev/zero, with a command such as "nc firewall 25 < /dev/zero".
