Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3445-1)

medium Nessus Plugin ID 103780

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3445-1 advisory.

 Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation in the Linux kernel contained a buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute arbitrary code with administrative privileges. (CVE-2016-8633)

 Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2017-14106)

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.
