Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4144-1 advisory.

 It was discovered that the XFS file system in the Linux kernel did not properly handle mount failures in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2018-20976)

 Benjamin Moody discovered that the XFS file system in the Linux kernel did not properly handle an error condition when out of disk quota. A local attacker could possibly use this to cause a denial of service.
 (CVE-2019-15538)
