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.

TUX is a kernel based HTTP server released under the GNU General Public License. It is able to serve static content, cache dynamic content, and coordinate with other HTTP servers to produce dynamic content.
An error exists when the TUX daemon received an oversized Host: header as part of a HTTP request. The request will result in an assertation failure and eventually in a kernel panic. At this point a system reboot will be required to regain normal functionality.
