9 PixieFail Vulnerabilities Discovered in TianoCore’s EDK II
A chain of 9 vulnerabilities in UEFI’s Preboot Execution Environment (PXE), dubbed PixieFail, was uncovered in a recent research. As the network boot process is a rather novice attack vector, only a few vulnerabilities received high severity status. Nonetheless, their sheer volume, along with the location in rather sensitive places, can create a mess if… Continue reading 9 PixieFail Vulnerabilities Discovered in TianoCore’s EDK II
