VHP
The Vulnerability History Project

Case Studies

We carefully choose which projects to study based on the following criteria:

  • Does this project keep good records? Specifically: do they faithfully disclose vulnerabilities? Can we trace the vulnerabilities to their version control fix commits?
  • Is the project large or meaningful enough to have it history be useful to professionals, students, and academics?
  • Does pursuing this data enable us to help draw some meaningful conclusions, potentially via statistics? This means broadening our scope via programming languages, technologies, open source models, etc.

Chromium Browser

systemd

"systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit." -systemd website

VHP has data on 32 vulnerabilities in systemd.

These vulnerabilities are collected from the National Vulnerabilities Database, acknowledged by the developers.

FFmpeg

"FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. under a wide variety of build environments, machine architectures, and configurations." -https://ffmpeg.org/

VHP has data on 287 vulnerabilities in FFmpeg.

These vulnerabilities are reported by the FFmpeg development team [on their site](https://ffmpeg.org/security.html)
