Description

Google Chrome contains an error in the 'ResourceHandle::start' function in WebCore/platform/network/chromium/ResourceHandle.cpp, as it allows starting network requests without a networking context. With a specially crafted web page that embeds an SVG resource in an <img> tag, a context-dependent attacker can load external resources as embedded CSS @import and @font-face URLs.
