This channel exploits an optimization that is data dependent, software transparent, and present in nearly all modern GPUs: graphical data compression. We present the first security-centric analysis of this optimization and demonstrate that it can be abused to leak visual data. For example, using GPU.zip, a malicious webpage can leak pixels from another webpage in the latest version of Google Chrome, violating the browser security model. […] Am I affected by GPU.zip?
