  • 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.
