Vulnerability Information

Synopsis

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

Description

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.74 to the following security updates :

- CVE-2017-1000111: fix race condition in net-packet code that could be exploited to cause out-of-bounds memory access (bsc#1052365).

- CVE-2017-1000112: fix race condition in net-packet code that could have been exploited by unprivileged users to gain root access. (bsc#1052311).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

To install this SUSE Security Update use YaST online_update. Alternatively you can run the command listed for your product :

SUSE OpenStack Cloud 6:zypper in -t patch SUSE-OpenStack-Cloud-6-2017-1328=1

SUSE Linux Enterprise Server for SAP 12-SP1:zypper in -t patch SUSE-SLE-SAP-12-SP1-2017-1328=1

SUSE Linux Enterprise Server 12-SP1-LTSS:zypper in -t patch SUSE-SLE-SERVER-12-SP1-2017-1328=1

SUSE Linux Enterprise Module for Public Cloud 12:zypper in -t patch SUSE-SLE-Module-Public-Cloud-12-2017-1328=1

To bring your system up-to-date, use 'zypper patch'.

How to Run

Here is how to run the SUSE SLES12 Security Update : kernel (SUSE-SU-2017:2150-1) 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 SuSE Local Security Checks plugin family.
On the right side table select SUSE SLES12 Security Update : kernel (SUSE-SU-2017:2150-1) plugin ID 102478.
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 suse_SU-2017-2150-1.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a suse_SU-2017-2150-1.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - suse_SU-2017-2150-1.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 suse_SU-2017-2150-1.nasl -t <IP/HOST>

Go back to menu.
