Published: 2020-01-29 04:00:31
CVE Author: NIST National Vulnerability Database (NVD)

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:C

Summary:
The remote host is missing an update for the 'linux-aws-5.0' Linux Distribution Package(s) announced via the USN-4258-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
It was discovered that the Atheros 802.11ac wireless USB device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15099) It was discovered that a race condition existed in the Virtual Video Test Driver in the Linux kernel. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. (CVE-2019-18683) It was discovered that the btrfs file system in the Linux kernel did not properly validate metadata, leading to a NULL pointer dereference. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2019-18885) It was discovered that the crypto subsystem in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19050, CVE-2019-19062) It was discovered that the RSI 91x WLAN device driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19071) It was discovered that the Broadcom Netxtreme HCA 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-2019-19077) It was discovered that the Atheros 802.11ac wireless USB 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-2019-19078) It was discovered that the Qualcomm IPC Router TUN device driver in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could possibly use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19079) It was discovered that the AMD GPU device drivers 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-2019-19082) Dan Carpenter discovered that the AppleTalk networking subsystem of the Linux kernel did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-19227) Or Cohen discovered ... Description truncated. Please see the references for more information.
