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.

VERSION Chrome Version: Chrome stable 42.0.2311.90 with Flash 17.0.0.169 Operating System: Win7 x64 SP1 REPRODUCTION CASE The Color constructor needs a target_mc object like a MovieClip, a TextField etc. While calling Color.setRGB with a custom object, it is possible to execute arbitrary AS2 code that might delete the target_mc object leading to a UAF.
