Título:	Ubuntu: Security Advisory for linux (USN-4302-1)
Resumen:	The remote host is missing an update for the 'linux'; package(s) announced via the USN-4302-1 advisory.
Descripción:	Summary: The remote host is missing an update for the 'linux' package(s) announced via the USN-4302-1 advisory. Vulnerability Insight: Paulo Bonzini discovered that the KVM hypervisor implementation in the Linux kernel could improperly let a nested (level 2) guest access the resources of a parent (level 1) guest in certain situations. An attacker could use this to expose sensitive information. (CVE-2020-2732) Gregory Herrero discovered that the fix for CVE-2019-14615 to address the Linux kernel not properly clearing data structures on context switches for certain Intel graphics processors was incomplete. A local attacker could use this to expose sensitive information. (CVE-2020-8832) It was discovered that the IPMI message handler implementation in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19046) It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19051) It was discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to possibly cause a denial of service (kernel memory exhaustion). (CVE-2019-19056) It was discovered that the Intel(R) Wi-Fi device driver in the Linux kernel device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19058) It was discovered that the Brocade BFA Fibre Channel device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19066) It was discovered that the Realtek RTL8xxx USB Wi-Fi device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19068) It was discovered that ZR364XX Camera USB device driver for the Linux kernel did not properly initialize memory. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15217) Affected Software/OS: 'linux' package(s) on Ubuntu 18.04 LTS, Ubuntu 16.04 LTS. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:L/Au:S/C:N/I:N/A:C
