Synopsis
========
Multiple vulnerabilities have been identified, the worst of which allow
arbitrary code execution on a user's system via a malicious Flash file.
Background
==========
The Adobe Flash Player is a renderer for the popular SWF file format,
which is commonly used to provide interactive websites, digital
experiences and mobile content.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-www/netscape-flash < 9.0.124.0 >= 9.0.124.0
Description
===========
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
(CVE-2007-6019).
* The ISS X-Force and the Zero Day Initiative reported an unspecified
input validation error that might lead to a buffer overflow
(CVE-2007-0071).
* 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,
CVE-2008-1655).
* 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.
Resolution
==========
All Adobe Flash Player users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot -v ">=net-www/netscape-flash-9.0.124.0"
