Title: Backspace Flaw Enables Linux Zero-Day Attack Post by: HCK on December 28, 2015, 09:00:22 pm Backspace Flaw Enables Linux Zero-Day Attack
Researchers last week revealed a zero-day flaw that lets attackers take over a Linux system by pressing the backspace key repeatedly. Pressing backspace 17 to 20 times will overwrite the highest byte of the return address of the grub_memset() function, ultimately causing a reboot by redirecting control flow to the 0x00eb53e8 address, according to the Cybersecurity Group at the Universitat Politecnica de Valencia.
