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://www.securityfocus.com/bid/35399/info Irssi is prone to an off-by-one, heap-based, memory-corruption vulnerability because it fails to properly bounds-check user-supplied data before copying it into a memory buffer. Attackers can exploit this issue to crash the vulnerable client, resulting in a denial-of-service condition. Given the nature of this issue, attackers may also be able to run arbitrary code within the context of the vulnerable application, but this has not been confirmed. Iirssi 0.8.13 is vulnerable; other versions may also be affected. The following example IRC command is available; please see the references for more information. : WALLOPS \001ACTION
