Denial-of-Service Attack Found In Btrfs File-System

Posted by timothy on from the at-that-range-a-hammer-works-too dept.

An anonymous reader writes "It's been found that the Btrfs file-system is vulnerable to a Hash-DOS attack, a denial-of-service attack caused by hash collisions within the file-system. Two DOS attack vectors were uncovered by Pascal Junod that he described as causing astonishing and unexpected success. It's hoped that the security vulnerability will be fixed for the next Linux kernel release." The article points out that these exploits require local access.

      Do I have to choose? Can I hang a medal on him, and then hang him? I'll make the medal 20 pounds to speed up the lynching.

    Words, they mean nothing! Take 'rarely' for example, who gives a shit, I'll read it as 'never' same thing.
