CVE Descriptions

The openssl extension in Ruby 2.x does not properly maintain the state of process memory after a file is reopened, which allows remote attackers to spoof signatures within the context of a Ruby script that attempts signature verification after performing a certain sequence of filesystem operations. NOTE: this issue has been disputed by the Ruby OpenSSL team and third parties, who state that the original demonstration PoC contains errors and redundant or unnecessarily-complex code that does not appear to be related to a demonstration of the issue. As of 20140502, CVE is not aware of any public comment by the original researcher

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.
