Descriptions du CVE

Multiple stack-based buffer overflows in RealNetworks RealPlayer before 17.0.4.61 on Windows, and Mac RealPlayer before 12.0.1.1738, allow remote attackers to execute arbitrary code via a long (1) version number or (2) encoding declaration in the XML declaration of an RMP file, a different issue than CVE-2013-6877.

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.
