Description:	Summary: The remote host is missing an update for the 'linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-gcp, linux-gcp-4.15, linux-gke-4.15, linux-kvm, linux-oracle, linux-raspi2, linux-snapdragon' package(s) announced via the USN-4711-1 advisory. Vulnerability Insight: It was discovered that the LIO SCSI target implementation in the Linux kernel performed insufficient identifier checking in certain XCOPY requests. An attacker with access to at least one LUN in a multiple backstore environment could use this to expose sensitive information or modify data. (CVE-2020-28374) Kiyin (Yin Liang ) discovered that the perf subsystem in the Linux kernel did not properly deallocate memory in some situations. A privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2020-25704) Affected Software/OS: 'linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-gcp, linux-gcp-4.15, linux-gke-4.15, linux-kvm, linux-oracle, linux-raspi2, linux-snapdragon' package(s) on Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04. Solution: Please install the updated package(s). CVSS Score: 5.5 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:P/A:N
