EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

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.

Percentile EPSS

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.

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.
