recoiledsnake writes "Google spent a lot of time yesterday talking up WebGL, but UK security firm Context seems to think users should disable the feature because it poses a serious security threat, and the US Computer Emergency Readiness Team is encouraging people to heed that advice. According to Context, a malicious site could pass code directly to a computer's GPU and trigger a denial of service attack or simply crash the machine. Ne'er-do-wells could also use WebGL and the Canvas element to pull image data from another domain, which could then be used as part of a more elaborate attack. Khronos, the group that organizes the standard, responded by pointing out that there is an extension available to graphics card manufacturers that can detect and protect against DoS attacks, but it did little to satisfy Context — the firm argues that inherent flaws in the design of WebGL make it very difficult to secure."
