Descriptions du CVE

Microsoft Internet Explorer 6 and 7 does not properly handle objects in memory that (1) were not properly initialized or (2) are deleted, which allows remote attackers to execute arbitrary code via vectors involving a call to the getElementsByTagName method for the STYLE tag name, selection of the single element in the returned list, and a change to the outerHTML property of this element, related to Cascading Style Sheets (CSS) and mshtml.dll, aka "HTML Object Memory Corruption Vulnerability." NOTE: some of these details are obtained from third party information. NOTE: this issue was originally assigned CVE-2009-4054, but Microsoft assigned a duplicate identifier of CVE-2009-3672. CVE consumers should use this identifier instead of CVE-2009-4054.

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.
