[dropcap]I[/dropcap]f you are an Apple MAC computer user and regularly use the incognito browsing point of Google Chrome, you can have dangerous difficulties. That’s because an engineering student at the University of Toronto, moniker Evan Andersen who discover a bug that convert graphics cards from Nvidia, exposing the comfortable that you thought would be hidden. Apparently, the problem is happening only on Macs.
Bug Content Exposed in Google Chrome Incognito Mode on Apple MAC PCs
Anderson made the discovery when you ran the Diablo III game and was surprised when a screen with pornographic content, seen by him in anonymous surfing was displayed. Like many people, Andersen was using anonymous way to hide what he was seeing friends and family who use the same computer. Fortunately, he was the one using the Mac when the bug happened the first time.
After some investigation, Andersen concluded that a bug in the drivers GPU Nvidia was the cause of the incident. “The GPU memory is not erased before releasing it to another application. This allows the leaking contents to another application. When the Chrome window was closed, its framebuffer was added to free the GPU memory, but not deleted. When Diablo III requested a framebuffer, the GPU offered what was used by Chrome. Since it was not deleted, it still contained the contents seen before, “said the student.
“This issue is related to memory management of Apple’s operating system, not with the graphics drivers from Nvidia,”
Said a company spokesman.
“The driver of Nvidia adheres to policies set by the operating system and is working as expected. We have not seen this problem in Windows, where all application-specific data are cleaned before the memory is freed for other applications.”
Andersen wrote a program to faithfully reproduce the bug, making a sweep in GPU memory. The student considers a serious mistake, since “Users can spy on each other.” Despite the seriousness of the error can not be exploited remotely, only in person. After the case became public, Nvidia said it can not fix the issue, given that the error is caused by the rules set by OS X. Apple does not comment on the case.
