8 New Spectre-Class Vulnerabilities (Spectre-NG) Found in Intel CPUs

A team of security researchers has reportedly discovered a total of eight new "Spectre-class" vulnerabilities in Intel CPUs, which also affect at least a small number of ARM processors and may impact AMD processor architecture as well. Dubbed Spectre-Next Generation, or Spectre-NG, the partial...

Integrated GPUs may allow side-channel and rowhammer attacks using WebGL ("Glitch")

Overview Some platforms with integrated GPUs, such as smartphones, may allow both side-channel and rowhammer attacks via WebGL, which may allow a remote attacker to compromise the browser on an affected platform. An attack technique that leverages these vulnerabilities is called "GLitch."...
