Ubuntu Security Notice 2777-1 - It was discovered that virtio networking in the Linux kernel did not handle fragments correctly, leading to kernel memory corruption. A remote attacker could use this to cause a denial of service (system crash) or possibly execute code with administrative privileges. Benjamin Randazzo discovered an information leak in the md (multiple device) driver when the bitmap_info.file is disabled. A local privileged attacker could use this to obtain sensitive information from the kernel. Various other issues were also addressed.
