Descriptions

Microsoft Windows Vista Gold, SP1, and SP2 and Server 2008 Gold and SP2 do not properly validate fields in SMBv2 packets, which allows remote attackers to cause a denial of service (infinite loop and system hang) via a crafted packet to the Server service, aka "SMBv2 Infinite Loop Vulnerability."

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.
