-
-*What is CVSS*
-    The Common Vulnerability Scoring System (CVSS) is an open, industry-standard framework used to measure and communicate the severity of software vulnerabilities, ranging from 0.0 to 10.0.
-
-*Why we need this Document*
-    It is important that FFmpeg CVEs have consistent and correct CVSS, not only for the obvious reason that one can recognize the severity of an issue at first glance.
-    But also as these numbers form the basis of rewards paid in bug bounty systems. Inconsistent CVSS could lead to unfair payouts.
-
-*What is this Document*
-    Prior 2026, FFmpeg had no guideline about CVSS.
-    This document describes how to select the CVSS for a FFmpeg related CVE. It currently only covers the Base Score.
-
-*What is the CVSS Base Score*
-    AV Attack Vector    (Network, Adjacent, Local, Physical)
-    AC Attack Complexity (Low, High)
-    PR Privileges Required (None, Low, High)
-    UI User Interaction (None, Required)
-    S  Scope (Unchanged, Changed)
-    C  Confidentiality (None, Low, High)
-    I  Integrity (None, Low, High)
-    A  Availability (None, Low, High)
-
-
-*Things people have set incorrectly*
-
-Below are general guidelines and in specific cases other things may apply.
-
-Attack Vector.
-    Quote from https://www.first.org/cvss/v3.1/user-guide
-        "Specifically, analysts should only score for Network or Adjacent when a vulnerability is bound to the network stack.
-         Vulnerabilities which require user interaction to download or receive malicious content (which could also be delivered locally, e.g., via USB drives) should be scored as Local."
-
-Availability.
-    FFmpeg Crashes -> AVAILABILITY IMPACT: Low
-    FFmpeg is frequently used as a short-lived, single-run process instead of a continuously running service that handles ongoing streams of user input. In that usage model, a crash usually causes only limited disruption.
-
-User Interaction
-    Please consider if an attacker can actually set the parameters required for an attack.
-    In general arbitrary filter parameters cannot be set by an attacker and require the user/account owner/admin to set them

@chapter Using FATE from your FFmpeg source directory

-If you want to run FATE on your machine, FFmpeg needs to be configured first.
-You may specify the location of samples during configuration by adding the
-argument @code{--samples=/path/to/fate-suite}.
+If you want to run FATE on your machine you need to have the samples
+in place. You can get the samples via the build target fate-rsync.
+Use this command from the top-level source directory:

@example
-./configure --enable-somelib --samples=/path/to/fate-suite
+make fate-rsync SAMPLES=fate-suite/
+make fate       SAMPLES=fate-suite/
@end example

-After successful configuration, you need to add and/or update the samples in place:
+The above commands set the samples location by passing a makefile
+variable via command line. It is also possible to set the samples
+location at source configuration time by invoking configure with
+@option{--samples=<path to the samples directory>}. Afterwards you can
+invoke the makefile targets without setting the @var{SAMPLES} makefile
+variable. This is illustrated by the following commands:

@example
-make fate-rsync
-@end example
-
-Now you are ready to run FATE:
-
-@example
-make fate
-@end example
-
-See @ref{makefile variables} for a list of arguments that can be added.
-
-If you did not set the samples path during configuration, or if you wish to
-override it just before starting FATE, you can do so in one of three ways.
-
-Either by setting a make variable:
-
-@example
-make fate-rsync SAMPLES=/path/to/fate-suite
-make fate       SAMPLES=/path/to/fate-suite
-@end example
-
-or by setting an environment variable for the current session:
-
-@example
-export FATE_SAMPLES=/path/to/fate-suite
+./configure --samples=fate-suite/
 make fate-rsync
 make fate
@end example

-or in isolation for a single command by prepending it:
+Yet another way to tell FATE about the location of the sample
+directory is by making sure the environment variable FATE_SAMPLES
+contains the path to your samples directory. This can be achieved
+by e.g. putting that variable in your shell profile or by setting
+it in your interactive session.

@example
-FATE_SAMPLES=/path/to/fate-suite make fate-rsync
-FATE_SAMPLES=/path/to/fate-suite make fate
+FATE_SAMPLES=fate-suite/ make fate
@end example

-This variable can also be set in your shell profile to make it permanent.
-
@float NOTE
 Do not put a '~' character in the samples path to indicate a home
 directory. Because of shell nuances, this will cause FATE to fail.
-Also, on Windows the path has to be relative to the build path
-which in this case is the FFmpeg source directory.
@end float

 Beware that some assertions are disabled by default, so mind setting
