Description:	Summary: The remote host is missing an update for the 'snapd' package(s) announced via the USN-4424-1 advisory. Vulnerability Insight: It was discovered that cloud-init as managed by snapd on Ubuntu Core 16 and Ubuntu Core 18 devices ran on every boot without restrictions. A physical attacker could exploit this to craft cloud-init user-data/meta-data via external media to perform arbitrary changes on the device to bypass intended security mechanisms such as full disk encryption. This issue did not affect traditional Ubuntu systems. (CVE-2020-11933) It was discovered that snapctl user-open allowed altering the XDG_DATA_DIRS environment variable when calling the system xdg-open. A malicious snap could exploit this to bypass intended access restrictions to control how the host system xdg-open script opens the URL. This issue did not affect Ubuntu Core systems. (CVE-2020-11934) Affected Software/OS: 'snapd' package(s) on Ubuntu 16.04, Ubuntu 18.04, Ubuntu 19.10, Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:P
