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.

Source: https://code.google.com/p/google-security-research/issues/detail?id=409&can=1&q=label%3AProduct-Flash%20modified-after%3A2015%2F8%2F17&sort=id There is a type confusion issue in TextRenderer.setAdvancedAntialiasingTable. If the font, insideCutoff or outsideCutoff are set to objects that are not integers, they are still assumed to be integers. A proof-of-concept is below: var antiAliasEntry_1 = {fontSize:10, insideCutoff:1.61, outsideCutoff:-3.43}; var antiAliasEntry_2 = {fontSize:"", insideCutoff:0.8, outsideCutoff:-0.8}; var arialTable:Array = new Array(antiAliasEntry_1, antiAliasEntry_2); TextRenderer.setAdvancedAntialiasingTable("Arial", "none", "dark", arialTable); This issue is low-impact because the type-confused objects are read into the font and cutoff values, which cannot be directly retreived from script. It is probably possible to determine the value read by doing hit tests on the text that is rendered (to see how big and clipped it is), but this would be fairly difficult. A sample SWF and fla are attached, these samples intentionally crash to demonstrate the issue.
