Summary[edit]

Description
English: Explanation of the Heartbleed bug:
  • In a normal Heartbeat request, the user queries the server saying "if you are really there, send me this four-letter word: "blah"" and the server answers with the message "blah" (consisting of four letters).
  • In a Heartbleed request, the attackers's query is "if you are really there, send me this 40,004-letter word: "blah"" and the server response is "blah" followed by whatever 40,000 characters of data happen to be after it in the server's active memory.
Deutsch: Veranschaulichung des Heartbleed Softwarefehlers:
  • In einer nomalen Heartbeat-Anfrage überprüft ein Benutzer den Status des Servers mit der Aufforderung "Wenn du wirklich da bist, sende mir diese 4 Zeichen: "blah"" und der Server antwortet mit der Nachricht "blah" (bestehend aus vier Zeichen).
  • In einer Heartbleed-Anfrage, lautet die Anfrage des Angreifers "Wenn du wirklich da bist, sende mir diese 40.004 Zeichen: "blah"" und die Antwort des Servers lautet "blah", gefolgt von den 40.000 Zeichen an Daten die sich zufällig nach dieser Antwort im aktiven Speicher des Servers befinden.

This file is translated using SVG <switch> elements. All translations are stored in the same file! Learn more.

For most Wikipedia projects, you can embed the file normally (without a lang parameter). The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:Heartbleed bug explained.svg|lang=en]] for the English version. Do not specify a lang parameter if it is not needed. The parameter may prevent the use of a subsequent translation.

To translate the text into your language, you can use the SVG Translate tool. Alternatively, you can download the file to your computer, add your translations using whatever software you're familiar with, and re-upload it with the same name. You will find help in Graphics Lab if you're not sure how to do this.
