Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-201309-24 (Xen: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in Xen. Please review the CVE identifiers referenced below for details. Impact :

Guest domains could possibly gain privileges, execute arbitrary code, or cause a Denial of Service on the host domain (Dom0). Additionally, guest domains could gain information about other virtual machines running on the same host or read arbitrary files on the host. Workaround :

The CVEs listed below do not currently have fixes, but only apply to Xen setups which have “tmem” specified on the hypervisor command line. TMEM is not currently supported for use in production systems, and administrators using tmem should disable it. Relevant CVEs: * CVE-2012-2497 * CVE-2012-6030 * CVE-2012-6031 * CVE-2012-6032 * CVE-2012-6033 * CVE-2012-6034 * CVE-2012-6035 * CVE-2012-6036

Solution

All Xen users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=app-emulation/xen-4.2.2-r1' All Xen-tools users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=app-emulation/xen-tools-4.2.2-r3' All Xen-pvgrub users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=app-emulation/xen-pvgrub-4.2.2-r1'

How to Run

Here is how to run the GLSA-201309-24 : Xen: Multiple vulnerabilities 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 Gentoo Local Security Checks plugin family.
On the right side table select GLSA-201309-24 : Xen: Multiple vulnerabilities plugin ID 70184.
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 gentoo_GLSA-201309-24.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a gentoo_GLSA-201309-24.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - gentoo_GLSA-201309-24.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 gentoo_GLSA-201309-24.nasl -t <IP/HOST>

Go back to menu.
