Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

USN-3385-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS.

Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code. (CVE-2017-1000112)

Andrey Konovalov discovered a race condition in AF_PACKET socket option handling code in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2017-1000111).

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

Update the affected packages.

How to Run

Here is how to run the Ubuntu 14.04 LTS : linux-lts-xenial vulnerabilities (USN-3385-2) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Ubuntu Local Security Checks plugin family.
On the right side table select Ubuntu 14.04 LTS : linux-lts-xenial vulnerabilities (USN-3385-2) plugin ID 102421.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl ubuntu_USN-3385-2.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a ubuntu_USN-3385-2.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - ubuntu_USN-3385-2.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state ubuntu_USN-3385-2.nasl -t <IP/HOST>

Go back to menu.
