Synopsis

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

Description

It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-10126)

Andrei Vlad Lutas and Dan Lutas discovered that some x86 processors incorrectly handle SWAPGS instructions during speculative execution. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2019-1125)

It was discovered that the PowerPC dlpar implementation in the Linux kernel did not properly check for allocation errors in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-12614)

It was discovered that a NULL pointer dereference vulnerability existed in the Near-field communication (NFC) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-12984)

Jann Horn discovered a use-after-free vulnerability in the Linux kernel when accessing LDT entries in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-13233)

Jann Horn discovered that the ptrace implementation in the Linux kernel did not properly record credentials in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2019-13272)

It was discovered that the Marvell Wireless LAN device driver in the Linux kernel did not properly validate the BSS descriptor. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-3846).

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 18.04 LTS / 19.04 : Linux kernel vulnerabilities (USN-4093-1) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

  1. Click to start a New Scan.
  2. Select Advanced Scan.
  3. Navigate to the Plugins tab.
  4. On the top right corner click to Disable All plugins.
  5. On the left side table select Ubuntu Local Security Checks plugin family.
  6. On the right side table select Ubuntu 18.04 LTS / 19.04 : Linux kernel vulnerabilities (USN-4093-1) plugin ID 127888.
  7. Specify the target on the Settings tab and click to Save the scan.
  8. 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-4093-1.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a ubuntu_USN-4093-1.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-4093-1.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-4093-1.nasl -t <IP/HOST>

Go back to menu.
