    • Heap buffer overflow in LibWebRTC allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. NOTE: The tarballs of WebKitGTK or WPE WebKit don’t ship LibWebRTC. Also the LibWebRTC support is disabled by default. You only are affected by this vulnerability if your build enabled the USE_LIBWEBRTC CMake option and used the repository as source instead of the tarballs.

We recommend updating to the latest stable versions of WebKitGTK and WPE WebKit. It is the best way to ensure that you are running safe versions of WebKit. Please check our websites for information about the latest stable releases.
