Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-4419-1)
Summary:	The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon' package(s) announced via the USN-4419-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon' package(s) announced via the USN-4419-1 advisory. Vulnerability Insight: It was discovered that a race condition existed in the Precision Time Protocol (PTP) implementation in the Linux kernel, leading to a use-after- free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-10690) Matthew Sheets discovered that the SELinux network label handling implementation in the Linux kernel could be coerced into de-referencing a NULL pointer. A remote attacker could use this to cause a denial of service (system crash). (CVE-2020-10711) It was discovered that the SCSI generic (sg) driver in the Linux kernel did not properly handle certain error conditions correctly. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2020-12770) It was discovered that the USB Gadget device driver in the Linux kernel did not validate arguments passed from configfs in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-13143) Shijie Luo discovered that the ext4 file system implementation in the Linux kernel did not properly check for a too-large journal size. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (soft lockup). (CVE-2020-8992) Affected Software/OS: 'linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon' package(s) on Ubuntu 14.04, Ubuntu 16.04. Solution: Please install the updated package(s). CVSS Score: 4.9 CVSS Vector: AV:L/AC:L/Au:N/C:N/I:N/A:C
