High Nessus Plugin ID 118968
Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
Felix Wilhelm discovered that the Xen netback driver in the Linux kernel did not properly perform input validation in some situations.
An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-15471)
It was discovered that the generic SCSI driver in the Linux kernel did not properly enforce permissions on kernel memory access. A local attacker could use this to expose sensitive information or possibly elevate privileges. (CVE-2017-13168)
It was discovered that an integer overflow existed in the CD-ROM driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-16658)
It was discovered that an integer overflow existed in the HID Bluetooth implementation in the Linux kernel that could lead to a buffer overwrite. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2018-9363).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
