Synopsis

The remote Red Hat host is missing a security update.

Description

An update for flash-plugin is now available for Red Hat Enterprise Linux 5 Supplementary and Red Hat Enterprise Linux 6 Supplementary.

Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in.

This update upgrades Flash Player to version 11.2.202.621.

Security Fix(es) :

* This update fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities, detailed in the Adobe Security Bulletin listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to crash, execute arbitrary code, or disclose sensitive information when the victim loaded a page containing the malicious SWF content. (CVE-2016-1096, CVE-2016-1097, CVE-2016-1098, CVE-2016-1099, CVE-2016-1100, CVE-2016-1101, CVE-2016-1102, CVE-2016-1103, CVE-2016-1104, CVE-2016-1105, CVE-2016-1106, CVE-2016-1107, CVE-2016-1108, CVE-2016-1109, CVE-2016-1110, CVE-2016-4108, CVE-2016-4109, CVE-2016-4110, CVE-2016-4111, CVE-2016-4112, CVE-2016-4113, CVE-2016-4114, CVE-2016-4115, CVE-2016-4116, CVE-2016-4117)

How to Run

Here is how to run the RHEL 5 / 6 : flash-plugin (RHSA-2016:1079) 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 Red Hat Local Security Checks plugin family.
On the right side table select RHEL 5 / 6 : flash-plugin (RHSA-2016:1079) plugin ID 91156.
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 redhat-RHSA-2016-1079.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2016-1079.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - redhat-RHSA-2016-1079.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 redhat-RHSA-2016-1079.nasl -t <IP/HOST>

Go back to menu.
