Ubuntu 16.04 LTS : Linux kernel vulnerabilities (USN-4346-1)

high Nessus Plugin ID 136089

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4346-1 advisory.

 It was discovered that the QLogic Fibre Channel driver in the Linux kernel did not properly check for error, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16233)

 It was discovered that the Intel Wi-Fi driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2019-16234)

 Tristan Madani discovered that the block I/O tracing implementation in the Linux kernel contained a race condition. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-19768)

 It was discovered that the virtual terminal implementation in the Linux kernel contained a race condition.
 A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2020-8648)

 Jordy Zomer discovered that the floppy driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-9383)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
