The current design allows arbitrary, Turing-complete programs to be sent to the GPU.

It may be possible to use WebGL to steal graphics image data from other sites.

It may be possible to provide malicious code, via the WebGL-enabled browser, that incorporates attacks on the GPU and graphics drivers, creating a Denial-of-Service attack that renders the whole system unusable.

They argue that there are defects in both the design and implementations of WebGL, which expose users to significant risks: The mention of hardware access by external code should have made security-conscious readers nervous and a UK security consulting firm, Context Information Security, has published a report outlining what they believe are some potentially serious security problems with WebGL. WebGL also allows Web pages and embedded applications to access and take advantage of the hardware acceleration capabilities present in some high-end graphics processors. The specification was developed and is maintained by the Khronos Group, a consortium of hardware manufacturers (such as Intel, AMD, and nVidia) and software developers (such as Google, Mozilla, and Adobe). One of these contexts is called WebGL it provides an API, modeled on the OpenGL library, which extends JavaScript for 2- and 3-D drawing without the use of plugins. This allows an HTML page to specify a graphics region, in which images can be dynamically constructed using, for example, JavaScript, and a drawing API similar to those used in graphical desktop applications.

One of the new elements introduced in HTML 5 is. The second is to provide a better format for supporting Web-based applications. The first is to attempt to arrive at a truly standard language, rather than the mostly-standard with accumulated “stuff” nature of HTML 4. The draft specification for HTML 5 is impressively long, and it is important to note that it is a work in progress, but there are a couple of unifying themes underlying the changes. Each of these has its own set of special features and distinguishing characteristics, but one common theme in recent releases has been providing improved support for HTML 5, the next version of the content description language used to create Web pages.

In the last few months, we have seen the release of several new browser versions, including Mozilla’a Firefox 4, Google’s Chrome 11, Microsoft’s Internet Explorer 9 (for Windows 7 and Vista only), and Oslo’s favorite browser, Opera Software’s Opera 11.10.
