Description:	Summary: The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-lts-trusty, linux-lts-xenial' package(s) announced via the USN-4135-2 advisory. Vulnerability Insight: Peter Pi discovered a buffer overflow in the virtio network backend (vhost_net) implementation in the Linux kernel. An attacker in a guest may be able to use this to cause a denial of service (host OS crash) or possibly execute arbitrary code in the host OS. (CVE-2019-14835) It was discovered that the Linux kernel on PowerPC architectures did not properly handle Facility Unavailable exceptions in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-15030) It was discovered that the Linux kernel on PowerPC architectures did not properly handle exceptions on interrupts in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-15031) Affected Software/OS: 'linux, linux-aws, linux-azure, linux-lts-trusty, linux-lts-xenial' package(s) on Ubuntu 12.04, Ubuntu 14.04. Solution: Please install the updated package(s).
