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=434&can=1&q=label%3AProduct-Flash%20modified-after%3A2015%2F8%2F17&sort=id The Shared Object constructor does not check that the object it is provided is of type Object before setting it to be of type SharedObject. This can cause problems if another method (such as Sound.loadSound) calls into script between checking the input object type, and casting its native object. A PoC is as follows: class subso extends Sound{ public function subso(f){ super("_level0.test"); var n = {valueOf : func}; _global.func = f; _global.t = this; var f2 = this.loadSound; f2.call(this, n, 1); } function func(){ _global.func(_global.t,"/sosuper.swf", "/sosuper.swf"); return 1; } } A sample fla, swf and AS file are attached. Note that this PoC needs to be hosted on a webserver to work and only works on 32-bit systems (tested on Windows Chrome). song1.mp3 should be put in the same folder on the server as the swf, it is needed for loadSound to work. This bug is likely only exploitable on 32-bit systems due to how the type-confused fields line up.
