CVE-2013-7324Public exploitNetwork attack vector

Excessive audio volume via unbounded stream control

Published Feb 17, 2020 · Updated Aug 6, 2024

Improper audio-volume handling in WebKitGTK 2.x allows remote attackers to force unexpectedly loud playback through malicious JavaScript. The GStreamer media backend passes script-controlled HTML media volume values directly to the PulseAudio stream sink instead of applying a relative software-volume boundary. Exposure requires a WebKitGTK browser or embedding application with GStreamer media support; PulseAudio flat-volume mode can raise output to the hardware maximum and resist mixer controls.
