This script is Copyright (C) 2008-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200804-21
(Adobe Flash Player: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in Adobe Flash:
Secunia Research and Zero Day Initiative reported a boundary error
related to DeclareFunction2 Actionscript tags in SWF files
The ISS X-Force and the Zero Day Initiative reported an unspecified
input validation error that might lead to a buffer overflow
Microsoft, UBsecure and JPCERT/CC reported that cross-domain policy
files are not checked before sending HTTP headers to another domain
(CVE-2008-1654) and that it does not sufficiently restrict the
interpretation and usage of cross-domain policy files (CVE-2007-6243).
The Stanford University and Ernst and Young's Advanced Security Center
reported that Flash does not pin DNS hostnames to a single IP
addresses, allowing for DNS rebinding attacks (CVE-2007-5275,
The Google Security Team and Minded Security Multiple reported multiple
cross-site scripting vulnerabilities when passing input to Flash
functions (CVE-2007-6637).

Impact :

A remote attacker could entice a user to open a specially crafted file
(usually in a web browser), possibly leading to the execution of
arbitrary code with the privileges of the user running the Adobe Flash
Player. The attacker could also cause a user's machine to send HTTP
requests to other hosts, establish TCP sessions with arbitrary hosts,
bypass the security sandbox model, or conduct Cross-Site Scripting and
Cross-Site Request Forgery attacks.

Workaround :

There is no known workaround at this time.
