CVE-2013-7324
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedWebkit-GTK 2.x (any version with HTML5 audio/video support based on GStreamer) allows remote attackers to trigger unexpectedly high sound volume via malicious javascript. NOTE: this WebKit-GTK behavior complies with existing W3C standards and existing practices for GNOME desktop integration.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceWebKit-GTK 2.x with GStreamer-based HTML5 audio/video support permits JavaScript to manipulate media elements to produce unexpectedly high volume without user consent or warning, potentially causing acoustic harm.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed WebKit-GTK versionQuery the installed webkitgtk package version using your system's package manager (e.g., dpkg -l libwebkit2gtk-*, rpm -qa | grep webkit, or pkg-config --modversion webkit2gtk-4.0)Affected if The version is greater than 2.0.0 and less than or equal to 2.26.4
-
Confirm GStreamer support is enabled in WebKit-GTKCheck if the WebKit-GTK build includes GStreamer support by examining the build configuration: look for --enable-gstreamer in the build flags, or check if libwebkit2gtk-4.0 depends on libgstreamer libraries (ldd on the library binary or check package dependencies)Affected if GStreamer support is compiled into the WebKit-GTK library and available at runtime
-
Verify HTML5 media playback capability is presentCheck whether the webkit2gtk package includes media backend support by examining the installed files: look for gstreamer-related files in the webkit package directory or check for the presence of MediaPlayer infrastructure in the libraryAffected if HTML5 audio/video elements are functional and the GStreamer media pipeline is active
-
Inspect WebKit-GTK media configurationReview the webkitgtk configuration or application logs for media-related settings: check for WebSettings that enable media playback, look at /usr/share/webkitgtk* or application-specific webkit configuration files where media.autoplay or media.enabled settings may be definedAffected if Media element playback is enabled without volume capping protections in place
You are affected if WebKit-GTK version is between 2.0.0 and 2.26.4 AND GStreamer-based HTML5 media playback is enabled, allowing JavaScript to set unbounded volume levels.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement volume capping or user confirmation requirements in WebKit-GTK's media pipeline before audio playback; consider adding a system-level volume limiter that overrides application-set levels.
